Publishing as Hidden Curriculum: How Learning to Publish Is a Piecemeal Process for Graduate Students

This presentation will share the results of a survey on what and how graduate students learn about the publishing process at an R1 university. This presentation will build on an earlier poster about our study, called “Making the Publishing Process More Transparent: Identifying a Baseline for Publishing Support through Researching Gaps between Graduate Students and Their Faculty Advisors’ Support,” at Transforming Libraries for Graduate Students (TLGS) 2022 (Stuit 2022). That poster covered our methods, literature review, and research questions. This full-length presentation will cover our findings and takeaways that other librarians may use in their work with graduate students. Faculty advisors of graduate students have many responsibilities in guiding their advisees to success in their programs, amidst many other demands on their time. On the flip side, graduate students must learn a number of skills and processes that are not covered explicitly in the curriculum. Learning this “hidden curriculum” happens inconsistently across the student body depending on what topics come up in conversation between students and advisors, what departmental or campus events/workshops that students have time to attend, and what their peers and experts in the field share with them. The hidden curriculum contains topics that students have to figure out as they go without formal support structures. Furthermore, there are calls to professionalize the university with more specialized training (Hayes 2023). This presentation will illustrate how the lack of training on how to publish disadvantages students, particularly first generation and minoritized scholars, and prevents students from optimizing their publishing efforts since they are learning as they go. We will cover when students start publishing (which is early), what students report that the expectations for publishing are, what guidance students receive from their advisors, and how they would like to learn about publishing. These findings indicate that students need more consistent support from the university on publishing. Specifically, when we set out with our research, we thought we would learn what areas that the library can rely on faculty advisors to cover and what gaps for the library to fill. However, we will share what we learned instead, which will also be shared in a forthcoming paper following the TLGS conference. During the presentation, we will provide interactive opportunities for attendees to help them identify their baseline assumptions about and experiences with graduate student publishing. We will share our methods, findings, and takeaways, as well as any supplemental materials, to provide attendees with actionable approaches to support graduate students with publishing

Chapter The economic-environmental impact analysis in the choice of the management of the dredging materials od a port basin in relation to the classification and the quality of the same: the experience of the port of Termoli (2018)

The work to be illustrated shows the comparison of the economic and environmental impact analysis in astudy case: "Dredging work on the seabed of the port of Termoli 2018". The entry into force of Ministerial Decree 173/2016 (ecotoxicological characterization of the sediments of the dredging area and of the diving area led). The new assessment required the search for solutions that summarized the economic aspects, linked to the financing available, and the adoption of a new technology that would allow a system process aimed at a better environmental protection

A Comparative Electrochemical Behaviour Study and Analytical Detection of the p-Nitrophenol Using Silver Solid Amalgam, Mercury, and Silver Electrodes

This work reports a comparative electrochemical behaviour study and p-nitrophenol analytical detection using silver solid amalgam, hanging dropping mercury, and silver electrodes. For this, square wave voltammetry was employed, where the analytical responses and the redox mechanisms could be compared for reduction processes of 4-nitrophenol by analysis of the voltammetric responses. The analytical performance of the electrode was evaluated and detection and quantification limits, recovery percentages, repeatability, and reproducibility for the silver solid amalgam and hanging dropping mercury electrodes presented similar values; the results presented for the silver electrode indicated worse analytical parameters than the other electrodes. The results indicate that the silver solid amalgam electrode can be considered a suitable tool and an interesting alternative for the analytical determination of 4-nitrophenol, as well as for the determination of other biological and environmentally interesting compounds that present analytical responses on mercury surfaces

A Cross-Sectional Survey on Burnout Prevalence and Profile in the Sicilian Population of Ambulance Driver-Rescuers

Introduction: Burnout is present at a high rate in emergency medicine. The ambulance driver-rescuers, who furnish first aid to the victims, are the non-medical part of the Italian 118-service staff. There is a lack of research on burnout risk in Italian Emergency Medical Services and, particularly, for this category of workers. The two Italian studies, including a little group of ambulance driver-rescuers, reported inconsistent findings. Hypothesis: This survey investigated for the first time the prevalence and exact profile of burnout in a large sample of Italian driver-rescuers. As a secondary aim, the study described how the items of the Italian version of the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) cluster in components in this sample. Methods: This cross-sectional census survey was conducted from June 2015 through May 2016 and involved all the driver-rescuers operating in Sicily, the biggest and most southern region of Italy. The subjects received a classification according to different profiles of burnout by using the Italian version of the MBI-HSS (burnout, engagement, disengagement, over-extension, and work-inefficacy). In order to explore the existence of independent factors, a Principal Component Analysis (PCA) was conducted on the survey to obtain eigenvalues >one for each component in the data. Results: The final sample comprised 2,361 responders (96.6% of the initial sample). Of them, 29.8% were in burnout (95% confidence interval [CI], 27.8% to 31.8%) and 1.7% presented a severe form (95% CI, 1.1% to 2.3%); 30.0% were engaged in their work (95% CI, 21.0% to 34.8%), 24.7% of responders were disengaged (95% CI, 22.9% to 26.5%), 1.2% presented an over-extension profile (95% CI, 0.8% to 1.7%), and 12.6% felt work-inefficacy (95% CI, 11.3% to 14.1%). The factors loaded into a five-factor solution at PCA, explaining 48.1% of the variance and partially replicating the three-factor structure. The Emotional Exhaustion (EE) component was confirmed. New dimensions from Personal Accomplishment (PA) and Depersonalization (DP) sub-scales described empathy and disengagement with patients, respectively, and were responsible for the increased risk of burnout. Conclusions: These results endorse the importance of screening and psychological interventions for this population of emergency workers, where burnout could manifest itself more insidiously. It is also possible to speculate that sub-optimal empathy skills could be related to the disengagement and work-inefficacy feelings registered

Polymorphism and structural disorder in melt-crystallized and fiber samples of syndiotactic copolymers of propane with 1-butene

The structural characterization of melt-crystallized samples and oriented fibers of syndiotactic copolymers between propene and 1-butene is reported. Melt-crystallized samples of copolymers are crystallized in the form I of syndiotactic polypropylene (s-PP) up to a Content of 1-butene of 60-70 mol %, although disorder in the alternation of right- and left-handed helical chains along both axes of the unit cell is present. More ordered modifications, close to the limit ordered, fully antichiral, form I of s-PP are obtained by crystallization at high temperatures only for samples containing small contents of 1-butene (1-2 mol %). The presence of 1-butene prevents that the order in the alternation of right- and left-handed helical chains develops at high crystallization temperatures. Samples with contents of 1-butene higher than 70 mol % crystallize in structures similar to that of form I of syndiotactic poly(1-butene). Fiber samples of copolymers with small content of 1-butene (1-2 mol %) present the same behavior of syndiotactic polypropylene. Stretched fibers are in the trans planar form III of s-PP,which transforms into the isochiral helical form II of s-PP upon the release of the tension. Mixtures of crystals in forms I and II of s-PP are obtained by annealing. With increasing the 1-butene content only the antichiral helical form I of s-PP is observed in the stretched fibers of the copolymers, as well as upon the release of the tension. The presence of 1-butene units, for contents higher than 4 mol %, prevents the formation of the trans planar form III of s-PP by stretching. For these samples the formation of form I of s-PP, instead of the isochiral form II, either in the stretched fibers or upon the release of the tension, is a further evidence that the isochiral helical form II of s-PP can be obtained only from fibers initially in the trans planar form III, through a cooperative conformational transformation which induce the formation of helical chains having the same chirality

Graminex pollen: phenolic pattern, colorimetric analysis and protective effects in immortalized prostate cells (PC3) and rat prostate challenged with LPS

Prostatitis, a general term describing prostate inflammation, is a common disease that could be sustained by bacterial or non-bacterial infectious agents. The efficacy of herbal extracts with antioxidant and anti-inflammatory effects for blunting the burden of inflammation and oxidative stress, with possible improvements in clinical symptoms, is under investigation. Pollen extracts have been previously reported as promising agents in managing clinical symptoms related to prostatitis. The aim of the present work was to evaluate the protective effects of Graminex pollen (GraminexTM, Deshler, OH, USA), a commercially available product based on standardized pollen extracts, in rat prostate specimens, ex vivo. In this context, we studied the putative mechanism of action of pollen on multiple inflammatory pathways, including the reduction of prostaglandin E2 (PGE2), nuclear factor kappa-light-chain-enhancer of activated B cells (NFB), and malondialdehyde (MDA), whose activities were significantly increased by inflammatory stimuli. We characterized by means of chromatographic and colorimetric studies the composition of Graminex pollen to better correlate the activity of pollen on immortalized prostate cells (PC3), and in rat prostate specimens challenged with Escherichia coli lipopolysaccharide (LPS). We found that Graminex pollen was able to reduce radical oxygen species (ROS) production by PC3 cells and MDA, NFB mRNA, and PGE2 levels, in rat prostate specimens. According to our experimental evidence, Graminex pollen appears to be a promising natural product for the management of the inflammatory components in the prostate

The invisible businessman: Nuclear physics, patenting practices,and trading activities in the 1930s

In the 1930s the production of patents for the protection of intellectual rights became central to the research activities of Enrico Fermi and his group, consistently with a research policy emerging within the Italian Fascist Regime. Behind their work was an international network consisting of businessmen, industrialists, and multinationals who helped them patent their method for the production of artificial radioactive elements and to promote its industrial exploitation. The lack of research funding combined with a more aggressive foreign policy of the regime made it impossible for the group to continue these activities in Rome, and in 1938 the promulgation of racial laws forced them to migrate abroad

Alternancia de la producción y comportamiento fenológico de la naranja ‘Valencia’ (Citrus sinensis [L.] Osbeck) en el trópico bajo húmedo de Colombia

In tropical conditions near the equatorial, precipitation is the main climatic factor that influences the growth and development of citrus plants. In a ‘Valencia’ orange orchard planted with 11-year-old trees located in the higher portion of the foothills of Corpoica, La Libertad Research Center in Villavicencio, Meta, Colombia, we recorded tree production data between the years 2008-2010. Information on the phenology of ten marked trees was gathered fortnightly from four cardinal directions using the methodology of Garrán et al. (1993) during the years 2009 and 2010. For this same period, the water balance was calculated for this orchard. The data were analyzed with descriptive statistics for most variables, and a mean-comparison test was carried out for the phenology observed at the cardinal points and for the correlation between annual precipitation and phenology. There was a positive correlation of 0.6 between rainfall and vegetative growth in 2009 and a negative correlation of -0.18 in 2010. There were no differences in phenology at the cardinal points. In 2008, the plants produced 168.8 kg/plant, causing the plants to present a strong vegetative growth and low yield (42.4 kg/tree) in 2009, whereas in 2010 there was an increase in the number of reproductive shoots, a decrease in the number of vegetative shoots and the harvest was 147.8 kg/tree. An alternation in the use of carbohydrates was observed between plant yield and vegetative growth.  En condiciones tropicales cerca de la línea ecuatorial, la precipitación es el principal factor climático que influye sobre el crecimiento y desarrollo de las plantas de cítricos. En un cultivo de naranja ‘Valencia’ de 11 años de edad ubicado en suelos de la terraza alta del piedemonte llanero en Corpoica, Centro de Investigación La Libertad, en Villavicencio, Meta, Colombia, se llevaron los registros de producción por árbol en los años 2008 a 2010. A diez árboles marcados se le tomó información quincenal de la fenología de la planta en los cuatro puntos cardinales utilizando la metodología de Garrán et al. (1993) durante los años 2009 y 2010. Para estos mismos años se calculó el balance hídrico para el cultivo. La información se analizó con estadística descriptiva para la mayoría de las variables, prueba de comparación de medias para la fenología por puntos cardinales y correlación entre la precipitación anual y la fenología. Se presentó una correlación positiva de 0,6 entre precipitación y crecimiento vegetativo en el año 2009 y negativa de -0,18 en el año 2010. No se presentaron diferencias en la fenología por puntos cardinales. En el año 2008 las plantas obtuvieron 168,8 kg/planta, lo que ocasionó que en el año 2009 estas presentaran una fuerte brotación vegetativa y baja cosecha (42,4 kg/árbol); mientras que en el año 2010 aumentaron los brotes reproductivos, disminuyeron los brotes vegetativos y la cosecha fue de 147,8 kg/árbol. Se presentó una alternancia en el uso de carbohidratos entre el rendimiento de la planta y la brotación vegetativa.
