Writing a thesis or dissertation is hard, and now that most theses and dissertations are deposited and distributed electronically, graduating students face an additional complication: they must decide whether they want to make their dissertations immediately open access (OA), or, at universities that require OA, they must come to terms with the fact that their work will be OA. In this presentation, I survey and scrutinize the anxieties and myths surrounding OA theses and dissertations.

Social signals are being increasingly used by science publishers to predict citation rate of papers using these alternative metrics (altmetrics). This presentation explores the growing importance of an online presence to the professional scientist. It offers three key tips to enhance your visibility - and along with it an improved long term citation rate - and signposts to tools to monitor the online impact of your work output.

Connecting Research and Researchers: How ORCID is Facilitating the Interoperable Exchange of Information, presented at the annual meeting of the Society for Scholarly Publishing, 30 May 2014. ABSTRACT: The publishing community has been an early and enthusiastic adopter of the work of ORCID, an independent non-profit organization with a twofold mission: to provide an open registry of unique identifiers for researchers, and to work with the scholarly community to ensure that this persistent identifier is embedded in research workflows. ORCID serves as a hub, linking existing identifiers, such as CrossRef and DataCite DOIs, ISNI organizational identifiers, and author identifiers including ResearcherId and ScopusAuthor ID with the ultimate goal of connecting researchers with their contributions. This session will provide an opportunity to learn about the status of ORCID integration into manuscript submission and production systems, into reviewer workflows, into conference systems, and into repositories and evaluation systems. A panel of experts from diverse publishing will provide practical examples and best practices for how the scholarly communications community is using ORCID.

Versão abreviada da minha pesquisa de mestrado sobre altmetria (do inglês altmetrics, alternative metrics). Trata-se de um novo campo dos estudos métricos da informação científica, que se ocupa da criação e utilização de indicadores relacionados à interação de usuários com produtos de pesquisa diversos no âmbito da Web Social – visualizações, downloads, citações, reutilizações, compartilhamentos, etiquetagens, comentários, entre outros – para gerar métricas de atenção e impacto científico. Além de constituir mais um passo na evolução dos estudos métricos da informação, a altmetria se apresenta também como reação à crise do atual modelo de publicação e avaliação na Ciência. A partir de pesquisa bibliográfica exploratória em fontes nacionais e internacionais, levantamos o estado da arte desta nova área de estudos. Apresentação que fiz em 29 de abril de 2014 para a disciplina Tópicos em Organização e Uso da Informação 2014/1 – COMUNICAÇÃO CIENTÍFICA E INTERNET: ESTUDOS MÉTRICOS DA INFORMAÇÃO NA WEB, ministrada pelo Prof. Ronaldo Ferreira de Araújo na Escola de Ciência da Informação da Universidade Federal de Minas Gerais (ECI/UFMG).

Estado da arte da Altmetria

Iara Vidal Pereira de Souza

Scholarly citations can be traced all the way back to the 15th century, but in the 21st century the internet, social media and the open access movement have made it easier than ever before for the public to engage with scholarly outputs. Altmetrics provide a measure of public engagement with web-native scholarship. They can be embedded into publishing platforms and institutional repositories as article-level metrics, and they provide evidence of impact for open access mandates. Three leading altmetrics aggregators are discussed: Altmetric.com; ImpactStory.org; PlumAnalytics.com. An institutional systems approach is recommended to mitigate the "pond-mentality" of the growing number of sources that provide measures of impact for research output. Research profiling systems are able to harvest most of these ponds and so save time for the researcher and research manager. In addition, national profiling systems would leverage economies of scale to increase the visibility and impact of all players, making it easier for potential investors and collaborators to find research partners. Altmetricians are challenged to develop a metric that measures the openness of a research entity.

Altmetrics as indicators of public impact

Altmetrics, another view on impact

Wouter Gerritsma

There are many good reasons why researchers might track the impact of their datasets. To provide supplementary evidence of influence for the next grant application or performance review or promotional opportunity. Or to track impact on the academy, on industry, on society or public policy. Could people or organizations engaging with a dataset become potential partners or collaborators? Altmetrics provide quantitative evidence of impact or influence by reporting scholarly and social online engagement with research datasets. They can be tracked using a range of services, from the more traditional citation databases to data and institutional repositories, and of course from altmetrics aggregator services. But we need to be careful not to create additional administrative burdens on time-poor researchers and also of the limitations in data citation practices or the lack thereof. One way we can achieve the former is to harvest altmetrics into our institutional repositories or data discovery services, saving time for the researcher by providing a systems solution.

Altmetrics to track the impact of datasets

Pat Loria

This presentation is a step by step introduction to ImpactStory, an online tool (by Heather Piwowar and Jason Priem) that helps researchers look at the impact of their research outputs. You can use ImpactStory to get an idea who is bookmarking, recommending, saving and citing your papers as well as other outputs (e.g. software and blog posts) and where this is happening. (Note: This is the version 7 of this presentation; due to several changes to ImpactStory a few updates have been required since the original upload)

E-Learn 2014 Abstract: Today digital footprints are left all over the Internet for others to find. This article reviews the means through which scholars can organize research and connect digital scholarship for increased visibility and impact. A survey of the literature on scholarship tools to provide connections for publishing records, academic citations, and digital identity management was done. The authors reviewed Researcher ID, ORCID, and Google Scholar Citations. The numbers of portals for synthesizing research output and related identity management platforms are increasing; however, understanding what this research impact might look like in the digital age can provide questions for assessment for understanding these traces of scholarship online.

[This presentation is based on my previous presentation, of the same title, at the LIASA 2014 conference. It was presented as a webinar for LIASA Higher Education Libraries Interest Group on 6/11/2014] Traditional bibliometric methods of evaluating academic research, such as journal impact factors and article citations, have been supplemented in the past 5-10 years by the development of altmetrics (alternative metrics or article level metrics). Altmetrics measures impact of research, data and publications, such as references in data and knowledge bases, article views, downloads and mentions in social media and news media. This presentation gives a brief background to altmetrics and demonstrates how Rhodes University librarians are using social media to raise the visibility of the research output of their institution.

Social media as a tool for researchers

About one-fifth of current scientific papers are being shared on Twitter. With 230 million active users and 24 percent of the U.S. online population using the microblogging platform, hopes are high that tweets mentioning scientific articles reflect some type of interest by the general public and might even be able to measure the societal impact of research. However, early studies show that most of the engagement with scientific papers on Twitter takes place among members of academia and thus reflects visibility within the scientific community rather than impact on society. At the same time, some tweets do not involve any human engagement but rather are generated automatically by Twitter bots. This talk focuses on identifying audiences on Twitter and teaches participants how to collect, analyze, visualize, and interpret diffusion patterns of scientific articles on Twitter. The course provides an overview of Altmetrics research and present the challenges – including methods and first results – of classifying Twitter user groups, with a particular focus on identifying members of the general public and measuring societal impact. The course will provide hands-on exercises and instructions on how to analyze by whom, when, and how scientific papers are shared on Twitter.

This workshop is divided in 2 parts. In the first part, I will discuss how/why academics use social media and online networks for scholarship, and explore the opportunities and tensions that exist in these spaces. In the second part of the workshop, I will facilitate small group and large group conversations on this topic based on participant interests. Potential topics of exploration may include but are not limited to: social media participation strategies; self-disclosures on social media; capturing and analyzing social media data; ethics of social media research; social media use for networked learning.

The traditional way to understand and demonstrate your impact–through citation counts–doesn’t meet the needs of today’s researchers. What Generation Open needs is altmetrics. In this presentation, we cover: - what altmetrics are and the types of altmetrics today’s researchers can expect to receive, - how you can track and share those metrics to get all the credit you deserve, and - real life examples of scientists who used altmetrics to get grants and tenure

Digital Scholarship and Impact Factors: Methods to Connect Your Research

Laura Pasquini

Social media are becoming more and more popular in scientific communication. Scientists use them for a range of purposes, from sharing publications, to blogging about their own or others’ research, conference tweeting, interpersonal communication and online participation, for example via Q&As on academic social network sites like ResearchGate and academia.edu. Moreover, many social media platforms can be used for impact measurement via so-called altmetrics. Altmetrics capture and aggregate social media metrics such as (re)tweets, Facebook likes, Mendeley bookmarks and Wikipedia cites. They can challenge or at least complement bibliometric impact measures, like the Journal Impact Factor and the h-index, which have been criticized on various grounds. This presentation first summarizes recent studies on social media adoption in science. It then focuses on altmetrics and summarizes key findings in that domain. Finally, it gives a hands-on introduction to altmetrics by demonstrating two prominent services: Impactstory and Altmetric.com.

A botany file is similar to a chemistry practical file but specifically focuses on experiments and observations related to plants. It typically includes detailed descriptions of plant-related experiments, such as germination studies, growth experiments, tissue culture techniques, plant anatomy investigations, and ecological surveys. The file may contain records of plant specimens collected, their classification, characteristics, and ecological significance. Additionally, it may include diagrams, photographs, drawings, tables, and data analysis related to plant research. Like a chemistry practical file, a botany file serves as a documentation of practical work conducted in the field of botany and is often used for assessment and educational purposes.

Botany is the branch of biology that deals with the scientific study of plants, including their structure, growth, reproduction, metabolism, development, and classification. It encompasses a wide range of topics, from the molecular biology of plant cells to the ecological relationships between plants and their environments. Botany is essential for understanding plant diversity, ecology, evolution, and the roles plants play in ecosystems and human societies.

Understanding circumstellar disks is of prime importance in astrophysics, however, their birth process remains poorly constrained due to observational and numerical challenges. Recent numerical works have shown that the small-scale physics, often wrapped into a sub-grid model, play a crucial role in disk formation and evolution. This calls for a combined approach in which both the protostar and circumstellar disk are studied in concert. Aims. We aim to elucidate the small scale physics and constrain sub-grid parameters commonly chosen in the literature by resolving the star-disk interaction. Methods. We carry out a set of very high resolution 3D radiative-hydrodynamics simulations that self-consistently describe the collapse of a turbulent dense molecular cloud core to stellar densities. We study the birth of the protostar, the circumstellar disk, and its early evolution (< 6 yr after protostellar formation). Results. Following the second gravitational collapse, the nascent protostar quickly reaches breakup velocity and sheds its surface material, thus forming a hot (∼ 103 K), dense, and highly flared circumstellar disk. The protostar is embedded within the disk, such that material can flow without crossing any shock fronts. The circumstellar disk mass quickly exceeds that of the protostar, and its kinematics are dominated by self-gravity. Accretion onto the disk is highly anisotropic, and accretion onto the protostar mainly occurs through material that slides on the disk surface. The polar mass flux is negligible in comparison. The radiative behavior also displays a strong anisotropy, as the polar accretion shock is shown to be supercritical whereas its equatorial counterpart is subcritical. We also f ind a remarkable convergence of our results with respect to initial conditions. Conclusions. These results reveal the structure and kinematics in the smallest spatial scales relevant to protostellar and circumstellar disk evolution. They can be used to describe accretion onto regions commonly described by sub-grid models in simulations studying larger scale physics.

Mustard, as a crop, is susceptible to a variety of pests that can affect its growth and yield. Here’s a rundown of some common pests that target mustard plants: Aphids: These small, sap-sucking insects can cause significant damage by feeding on the leaves and stems. Aphids also excrete a sticky substance known as honeydew, which can lead to the growth of sooty mold on the plants. Flea Beetles: These tiny beetles jump like fleas when disturbed and chew small holes in the leaves. They are particularly damaging in the early growth stages of the plant. Cabbage Loopers: The larvae of a type of moth, these caterpillars are known for their distinctive looping movement. They chew large holes in the leaves and can defoliate plants if present in large numbers. Diamondback Moth Larvae: Another caterpillar pest, these larvae chew small holes in the leaves and can cause extensive damage, especially when infestations are heavy. Whiteflies: These are tiny, winged insects that feed on plant sap and can quickly become a problem in greenhouse or close planting conditions. Like aphids, they also secrete honeydew. Cutworms: These are the larvae of certain types of moths and are known for cutting young plants at the stem base at ground level. They are most destructive during the night. Root Maggots: The larvae of root maggot flies, these pests attack the roots of mustard plants, causing wilting and potentially killing young plants. Harlequin Bugs: These are colorful stink bugs that suck the sap from mustard plant stems and leaves, causing the leaves to become stippled, wilt, and eventually die if the infestation is severe. Mustard Sawfly: The larvae of the mustard sawfly can cause considerable defoliation, as they feed voraciously on the leaves. Clubroot: Caused by a fungus-like organism, clubroot affects the roots, causing them to swell and distort. While technically a disease, it is often associated with pest management because controlling it involves similar preventative strategies. Control Measures: Managing pests in mustard involves a combination of cultural, biological, and chemical methods. Crop rotation, resistant varieties, timely sowing, maintaining plant health, and using natural predators like ladybugs and parasitic wasps can help keep pest populations under control. Chemical pesticides should be used as a last resort due to their potential impact on the environment and non-target species.

Wepresent Atacama Large Millimeter/submillimeter Array 12-m, 7-m, and Total Power Array observations of the FUOrionis outbursting system, covering spatial scales ranging from 160 to 25,000 au. The high-resolution interferometric data reveal an elongated 12CO(2–1) feature previously observed at lower resolution in 12CO(3–2). Kinematic modeling indicates that this feature can be interpreted as an accretion streamer feeding the binary system. The mass infall rate provided by the streamer is significantly lower than the typical stellar accretion rates (even in quiescent states), suggesting that this streamer alone is not massive enough to sustain the enhanced accretion rates characteristic of the outbursting class prototype. The observed streamer may not be directly linked to the current outburst, but rather a remnant of a previous, more massive streamer that may have contributed enough to the disk mass to render it unstable and trigger the FU Orionis outburst. The new data detect, for the first time, a vast, slow-moving carbon monoxide molecular outflow emerging from this object. To accurately assess the outflow properties (mass, momentum, and kinetic energy), we employ 13CO(2–1) data to correct for optical depth effects. The analysis indicates that the outflow corresponds to swept-up material not associated with the current outburst, similar to the slow molecular outflows observed around other FUor and Class I protostellar objects.

Theoretical predictions and observational data indicate a class of sub-Neptune exoplanets may have water-rich interiors covered by hydrogen-dominated atmospheres. Provided suitable climate conditions, such planets could host surface liquid oceans. Motivated by recent JWST observations of K2-18 b, we self-consistently model the photochemistry and potential detectability of biogenic sulfur gases in the atmospheres of temperate sub-Neptune waterworlds for the first time. On Earth today, organic sulfur compounds produced by marine biota are rapidly destroyed by photochemical processes before they can accumulate to significant levels. Domagal-Goldman et al. suggest that detectable biogenic sulfur signatures could emerge in Archean-like atmospheres with higher biological production or low UV flux. In this study, we explore biogenic sulfur across a wide range of biological fluxes and stellar UV environments. Critically, the main photochemical sinks are absent on the nightside of tidally locked planets. To address this, we further perform experiments with a 3D general circulation model and a 2D photochemical model (VULCAN 2D) to simulate the global distribution of biogenic gases to investigate their terminator concentrations as seen via transmission spectroscopy. Our models indicate that biogenic sulfur gases can rise to potentially detectable levels on hydrogen-rich water worlds, but only for enhanced global biosulfur flux (20 times modern Earth’s flux). We find that it is challenging to identify DMS at 3.4 μm where it strongly overlaps with CH4, whereas it is more plausible to detect DMS and companion byproducts, ethylene (C2H4) and ethane (C2H6), in the mid-infrared between 9 and 13 μm.

Context. WASP-76 b has been a recurrent subject of study since the detection of a signature in high-resolution transit spectroscopy data indicating an asymmetry between the two limbs of the planet. The existence of this asymmetric signature has been confirmed by multiple studies, but its physical origin is still under debate. In addition, it contrasts with the absence of asymmetry reported in the infrared (IR) phase curve. Aims. We provide a more comprehensive dataset of WASP-76 b with the goal of drawing a complete view of the physical processes at work in this atmosphere. In particular, we attempt to reconcile visible high-resolution transit spectroscopy data and IR broadband phase curves. Methods. We gathered 3 phase curves, 20 occultations, and 6 transits for WASP-76 b in the visible with the CHEOPS space telescope. We also report the analysis of three unpublished sectors observed by the TESS space telescope (also in the visible), which represents 34 phase curves. Results. WASP-76 b displays an occultation of 260±11 and 152±10 ppm in TESS and CHEOPS bandpasses respectively. Depending on the composition assumed for the atmosphere and the data reduction used for the IR data, we derived geometric albedo estimates that range from 0.05 ± 0.023 to 0.146 ± 0.013 and from <0.13 to 0.189 ± 0.017 in the CHEOPS and TESS bandpasses, respectively. As expected from the IR phase curves, a low-order model of the phase curves does not yield any detectable asymmetry in the visible either. However, an empirical model allowing for sharper phase curve variations offers a hint of a flux excess before the occultation, with an amplitude of ∼40 ppm, an orbital offset of ∼−30◦ , and a width of ∼20◦ . We also constrained the orbital eccentricity of WASP-76 b to a value lower than 0.0067, with a 99.7% confidence level. This result contradicts earlier proposed scenarios aimed at explaining the asymmetry observed in high-resolution transit spectroscopy. Conclusions. In light of these findings, we hypothesise that WASP-76 b could have night-side clouds that extend predominantly towards its eastern limb. At this limb, the clouds would be associated with spherical droplets or spherically shaped aerosols of an unknown species, which would be responsible for a glory effect in the visible phase curves.
