Abstract
Jets and outflows are ubiquitous phenomena in astrophysics, found in our Galaxy in diverse environments, from the formation of stars to late-type stellar objects. We present observations conducted with the 305 m Arecibo Telescope of the preplanetary nebula CRL 618 (Westbrook Nebula)—a well-studied late-type star that has developed bipolar jets. The observations resulted in the first detection of 4765 MHz OH in a late-type stellar object. The line was narrow (FWHM ∼ 0.6 km s−1) and ∼40 km s−1 blueshifted with respect to the systemic velocity, which suggests association with the expanding jets/bullets in CRL 618. We also report nondetection at Arecibo of any other OH transition between 1 and 9 GHz. The nondetections were obtained during the observations in 2008, when the 4765 MHz OH line was first discovered, and also in 2015 when the 4765 MHz OH line was not detected. Our data indicate that the 4765 MHz OH line was a variable maser. Modeling of the 4765 MHz OH detection and nondetection of the other transitions is consistent with the physical conditions expected in CRL 618. The 4765 MHz OH maser could originate from dissociation of H2O by shocks after sublimation of icy objects in this dying carbon-rich stellar system, although other alternatives such as OH in an oxygen-rich circumstellar region associated with a binary companion are also possible.

Abstract
Using high-cadence observations from the Zwicky Transient Facility at low Galactic latitudes, we have discovered a new class of pulsating, hot compact stars. We have found four candidates, exhibiting blue colors (g − r ≤ −0.1 mag), pulsation amplitudes of >5%, and pulsation periods of 200–475 s. Fourier transforms of the light curves show only one dominant frequency. Phase-resolved spectroscopy for three objects reveals significant radial velocity, T
eff, and

variations over the pulsation cycle, which are consistent with large-amplitude radial oscillations. The mean T
eff and

for these stars are consistent with hot subdwarf B (sdB) effective temperatures and surface gravities. We calculate evolutionary tracks using MESA and adiabatic pulsations using GYRE for low-mass, helium-core pre-white dwarfs (pre-WDs) and low-mass helium-burning stars. Comparison of low-order radial oscillation mode periods with the observed pulsation periods show better agreement with the pre-WD models. Therefore, we suggest that these new pulsators and blue large-amplitude pulsators (BLAPs) could be members of the same class of pulsators, composed of young ≈0.25–0.35 M
⊙ helium-core pre-WDs.
Making Known and Available: The importance of digitization of a historical malacological collection in the Science Museum of the University of Coimbra
Authors: Breves André , Girão da Cruz M. Teresa , Casaleiro Pedro 
Published: June 2019

The Science Museum of the University of Coimbra (MCUC) manages the oldest zoological collections in Portugal. The molluscs are among the most relevant invertebrates within this collection, with over one hundred thousand specimens. A significant part of the Portuguese malacological collection in MCUC comes from the Madeira Archipelago, a group of oceanic islands with a high diversity of terrestrial molluscs and a hotspot of endemic taxa.
A recent review of land snails from Madeira hosted at the MCUC revealed that there were around 130 lots and 2,000 specimens offered by naturalists since the 19th Century and none of them had been previously digitized. A significant number of these specimens was offered by António da Costa de Paiva (Barão de Castelo de Paiva) who described ten land snail species from the Madeira Archipelago in 1866 and published an extensive monograph on non-marine molluscs in 1867.
The main goal of our work was to carry out the inventory of the mollusc collections from the Madeira Archipelago in the database of MCUC, and to discuss the importance of specimens’ digitization for making the collections known and available to researchers and the general public.
We inserted data for 1,916 specimens of the Madeira Archipelago collection in the MCUC database ‘In Natura - Natural Heritage Management’ with information on their taxonomy, old inventory numbers (if available), correspondent lot, collector and the study areas, complemented with information about habitat, among others. In addition, we also included photographs of the lots and of some of the most remarkable individuals in the database. The specimens were then reconditioned and identified in the general mollusc collection, although the identification and designation of the type material are still lacking.
Digitization is crucial in the field of biological collections in order to transfer specimen data onto worldwide accessible repositories, potentially benefiting the work of researchers and other stakeholders in the ecological and conservation communities. For instance, even when researchers are intensively searching for a type material in a certain collection, if the data are neither known nor available, they cannot trace it and compare it with their material.
Thus, this work is fundamental for the accessibility of the malacological collections in the MCUC for researchers and also the society-at-large that has the possibility of consulting them through the digital museum (http://museudaciencia.inwebonline.net), as well as for the dissemination of the important historical and scientific heritage of the University of Coimbra and Portugal, both nationally and internationally.
SpOccSum: An easy-to-use Python tool to summarize species occurrence data from material examined lists in taxonomic revisions
Authors: Trizna Michael , Dikow Torsten 
Published: June 2019

Taxonomic revisions contain crucial biodiversity data in the material examined sections for each species. In entomology, material examined lists minimally include the collecting locality, date of collection, and the number of specimens of each collection event. Insect species might be represented in taxonomic revisions by only a single specimen or hundreds to thousands of specimens. Furthermore, revisions of insect genera might treat small genera with few species or include tens to hundreds of species. Summarizing data from such large and complex material examined lists and revisions is cumbersome, time-consuming, and prone to errors. However, providing data on the seasonal incidence, abundance, and collecting period of species is an important way to mobilize primary biodiversity data to understand a species’s occurrence or rarity. Here, we present SpOccSum (Species Occurrence Summary)—a tool to easily obtain metrics of seasonal incidence from specimen occurrence data in taxonomic revisions. SpOccSum is written in Python (Python Software Foundation 2019) and accessible through the Anaconda Python/R Data Science Platform as a Jupyter Notebook (Kluyver et al. 2016). The tool takes a simple list of specimen data containing species name, locality, date of collection (preferably separated by day, month, and year), and number of specimens in CSV format and generates a series of tables and graphs summarizing:

number of specimens per species,

number of specimens collected per month,

number of unique collection events, as well as

earliest, and

most recent collecting year of each species.

number of specimens per species,
number of specimens collected per month,
number of unique collection events, as well as
earliest, and
most recent collecting year of each species.
The results can be exported as graphics or as csv-formatted tables and can easily be included in manuscripts for publication. An example of an early version of the summary produced by SpOccSum can be viewed in Tables 1, 2 from Markee and Dikow (2018). To accommodate seasonality in the Northern and Southern Hemispheres, users can choose to start the data display with either January or July. When geographic coordinates are available and species have widespread distributions spanning, for example, the equator, the user can itemize particular regions such as North of Tropic of Cancer (23.5˚N), Tropic of Cancer to the Equator, Equator to Tropic of Capricorn, and South of Tropic of Capricorn (23.5˚S). Other features currently in development include the ability to produce distribution maps from the provided data (when geographic coordinates are included) and the option to export specimen occurrence data as a Darwin-Core Archive ready for upload to the Global Biodiversity Information Facility (GBIF).
Reaching an Established but Growing Network: Use-case from Canadensys
Authors: Sinou Carole , Bruneau Anne , Paul Deborah L , Kennedy Mary 
Published: June 2019

Canadensys is an associate GBIF node in Canada, officially established as a node in 2014, but publishing data on GBIF since 2011. Since then, Canadensys has grown from nine institutions to a network of nearly 25 institutions that publish biodiversity data and we have migrated from an in-house explorer, to a Living Atlases (LA) framework. Canadensys publishes data curated or collected by Canadian universities, museums, as well as municipalities and non govermental organizations (NGOs).
Establishing a new network can be challenging, but several resources and programs exist to help node managers and node participants initiate the publication process.
Keeping an established network alive while continuing to grow and to develop new methods and technologies is also an important challenge, especially in a context where institutions are geographically separated across large distances, and where funds are scarce or mostly oriented towards highly innovative projects.
With the aim to reach both established and new participants across Canada and from adjacent regions in the USA, and in order to help them to familiarize themselves with the new framework based on LA, we organized three workshops on data publication and data usage. Partially funded through a GBIF CESP project, this series of workshops was developed in partnership with international, regional and national partners such as iDigBio, OBIS Canada and GBIF Spain. The workshops helped new participants prepare and publish data, and allowed established publishers to enrich and update their resources on Canadensys and GBIF. The project also highlighted some of the challenges our network is facing, such as funding, infrastructure, human resources, and communication. Feedback from participants shows that the workshops were successfull in terms of capacity enhancement, giving knowledge and tools to data manager in order to prepare and publish standardize data, as well as to transfer that knowledge in their respective institutions. All materials and documentation developed during this project will be made available on Canadensys, allowing everyone interested to follow the curriculum. Sharing our experience will be useful for other nodes wanting to introduce the LA framework to their users and to enhance capacities in the network.
Zenodo, an Archive and Publishing Repository: A tale of two herbarium specimen pilot projects
Authors: Dillen Mathias , Groom Quentin , Agosti Donat , Nielsen Lars 
Published: June 2019

Zenodo (https://zenodo.org) is an open-access repository operated by CERN (European Organization for Nuclear Research), which provides researchers with an easy and stable platform to archive and publish their data and other output, such as software tools, manuals and project reports. In the context of the ICEDIG (Innovation and Consolidation for Large scale Digitisation of Natural Heritage) project, Zenodo was investigated for its usability as a platform where digitized images of collection specimens could be archived and published. In a production digitization pipeline, we foresee the automated archiving of daily image production. If Zenodo could be used for this purpose, such a process would also immediately mean that data and images are published FAIR-ly (Findable, Accessible, Interoperable and Reusable) within hours of their creation.
To evaluate performance of the system, we first used a test dataset of 1800 herbarium specimen images, which was uploaded using Zenodo's API (Application Programming Interface) (Dillen et al. 2019). This dataset includes lossless TIFF images, label-segmented overlays and JSON-LD (JavaScript Object Notation for Linked Data) metadata using DwC (Darwin Core) terminology, constituting over 208 gigabytes of data. In addition, for all individual digital specimens the data about the specimen (in DwC) as well as metadata about its deposition on Zenodo (in Zenodo's internal data model) were available in multiple machine-readable formats. All data in DwC were provided as linked data with their DwC identifiers (e.g. http://rs.tdwg.org/dwc/terms/basisOfRecord). All individual specimens received minted DOIs (Digital Object Identifiers). A second upload of 280,000 herbarium JPEG images from a single institution (ca. 1 terabyte of data) with limited metadata (but using the same approach) was launched as well.
In this presentation, the workflow for proper usage of the API will be described as well as some performance metrics, flexibilities and functionalities of the platform. Some issues and potential developments to tackle them will be discussed. Currently, the rate of ingestion into Zenodo seems only fast enough for small scale digitization pipelines. However, a modest improvement in transfer rate would make this a realistic proposition for large volume usage.
SwissCollNet – A National Initiative for Natural History Collections in Switzerland
Authors: Frick Holger , Stieger Pia , Scheidegger Christoph 
Published: June 2019

More than 60 million specimens are housed in geological and biological collections in numerous museums and botanical gardens located all over Switzerland. They are of national and international origin. Taken together they form an entity with a high scientific value and international recognition for their contribution to scientific research. Due to the federalistic organisation of Switzerland, natural history collections are located and curated in numerous institutions. So far, no common strategy for digitisation, documentation and long-term data archiving has been developed.
This shortcoming has been widely identified by concerned parties. Under the lead of the Swiss Academy of Sciences, several organisations have assembled information about Swiss natural history collections. They identified measures to be taken to promote the scientific and educational potential of natural history collections in Switzerland (Beer et al. 2019).
With a national initiative, the Swiss Natural History Collections Network (SwissCollNet) aims to unite Swiss natural history collections under a common vision and with a common strategy. The goal is to promote the collections themselves and to harness the scientific and educational potential of these collections for research and training. SwissCollNet consists of representatives of research, teaching, museums and botanical gardens, the data centers for information on the national fauna and flora, the Swiss Systematics Society and the Swiss node of GBIF, the Global Biodiversity Information Facility.
The initiative aims to foster research on natural history collections. It will provide a single decentralised data infrastructure framework for Swiss research related to natural history. It will help to harmonise nationwide collection data management, digitisation and long-term data archiving. It will facilitate identification of specimens and revision of taxonomic groups. New research techniques, fast-evolving computer technologies and internet connectivity, create new opportunities for deciphering and using the wealth of information housed in Swiss and international collections.
The development of an agreed strategy and research priorities on a national scale will allow fluent, fluid and permanent collaboration across all Swiss natural history collections by promoting interoperability and unified access to collections as well as creating opportunities for scientific collaboration and innovation. This national approach will create an internationally compatible research data infrastructure, while respecting and integrating regional and decentralized conditions and requirements. Thus, it will maximize the impact for science, policy and society.
New Uses for an Old and Abandoned Colonial Collection: The herpetological collection of the Instituto de Investigação Científica Tropical (Lisbon, Portugal)
Authors: Pires Ceríaco Luis Miguel , Pimentel Marques Mariana 
Published: June 2019

The herpetological collections of the Instituto de Investigação Científica Tropical (Lisbon, Portugal) are the largest and most diverse collections of amphibians and reptiles in the country. These were collected in the mid-twentieth century in the former Portuguese colonies in Africa and Asia, and were the object of study of several naturalists that used them to describe and catalogue the herpetofauna of those areas. After the independence of these colonies in the mid 1970's, the research on this material nearly halted, and the collections became abandoned, without proper curation and lacking accessibility. In 2015, we started a process to recover these collections (Fig. 1). This encompassed basic curation, e.g. cleaning and substituting jars and fluid preservatives, cataloguing the entire collection, digitizing and georeferencing all the specimens, and making data available through the Global Biodiversity Information Facility at GBIF.org. While doing this, each specimen was also linked to its bibliographic data, its taxonomic identity carefully reviewed, and rare and important specimens (e.g., type specimens) flagged.
Currently, the collection is completely accessible, both physically and electronically, and it is being used by researchers and students around the world. Some results have already been published including the description of species new to science (Ceríaco et al. 2016, Ceríaco et al. 2017, Ceríaco 2015, Soares et al. 2018), new country checklists, the publication of an Atlas of Angolan Herpetofauna (Marques et al. 2018), International Union for Conservation of Nature (IUCN) Red List assessments, and student training.
This presentation provides an overview of the recovery process of the collection, discusses strategies on how to digitize and make historical collections available to the community, and demonstrates how biological collections amassed during colonial times can be of extreme importance to the study and preservation of present day biodiversity.
Marie, figure et mère de l’Église vivant de la Parole de Dieu. Une lecture de l’exhortation Verbum Domini
Authors: Weill Marie-David 
Published: June 2019

Dans l’exhortation apostolique post-synodale Verbum Domini (novembre 2010), sur la Parole de Dieu dans la vie et la mission de l’Église, Benoît xvi recueille les acquis du renouveau marial promu par le concile Vatican ii , qui reconnaît à Marie une véritable place dans la nature profonde de l’Église. Il exhorte « les chercheurs à approfondir le plus possible le rapport entre la mariologie et la théologie de la Parole », et espère « en tirer un grand bénéfice autant pour la vie spirituelle que pour les études théologiques et bibliques » ( Verbum Domini 27). L’A. propose quelques pistes de réflexion dans ce sens.
6. Les sciences sociales, contre la data science ?
Authors: Ollion Étienne 
Published: June 2019

La data science a fait une apparition spectaculaire ces dernières années. Dans les entreprises, au sein de l’administration, mais aussi dans le domaine de la recherche, ce qu’on présente comme une discipline nouvelle susceptible de renouveler en profondeur notre connaissance du monde a donné lieu à de nombreux investissements. En quoi consiste cette nouvelle pratique, et quelles sont ses origines intellectuelles ? Pourquoi un tel intérêt, et s’agit-il d’une mode ? Analysant ce mouvement à la lumière de l’histoire des sciences sociales, l’article propose d’éclairer ces questions, ainsi que certaines tendances dans l’évolution des modes de connaissance du monde social.

Cet article tend à montrer les mécanismes qui sont à l’œuvre dans ce qui représente l’un des paradoxes de l’économie numérique : les applications que nous utilisons sur nos smartphones et autres tablettes génèrent toute une économie, et pourtant elles sont, pour la grande majorité d’entre elles, gratuites.
Du péché originel à la blessure originelle
Authors: Arènes Jacques 
Published: June 2019

Résumé Dans la culture contemporaine, la culpabilité s’est déplacée du face-à-face avec autrui à celui avec soi-même. Le « traitement » psychique de la culpabilité n’a pas disparu, mais s’est transformé pour laisser la place à de nouvelles formes subjectives de la culpabilité, plus archaïques et plus proches de la honte, dont l’objet ne touche pas nécessairement à un fait précis, mais à une angoisse d’insuffisance plus globale. La figure ancienne de « l’homme coupable » a, par ailleurs, laissé la place à celle de l’« homme blessé » : cette présence marquée du thème de la blessure devient alors une dimension importante des cheminements spirituels contemporains. Le volontarisme de la blessure – « guérir » d’abord l’estime de soi mise à mal – a ainsi remplacé l’ancien volontarisme moral.
La conscience du péché, observations d’un confesseur
Authors: Roland-Gosselin Miguel 
Published: June 2019

Résumé Les pénitents se présentent en confession avec des dispositions intérieures variées, différentes manières de se rapporter à soi, au péché et à Dieu. Cet article établit un essai de typologie. Mais le plus important est d’observer que dans tous les cas de figure, où qu’en soit le pénitent, l’enjeu reste le même : il est de progresser vers le Christ, autrement dit de prendre conscience que l’amour appelle plus loin. Cet article veut indiquer comment la démarche sacramentelle peut contribuer à l’éveil de la conscience, et quel rôle y joue le prêtre, essentiellement par son attitude évangélique et par sa façon de renvoyer à l’Évangile. L’article rappelle surtout que la connaissance de son propre péché est une grâce à demander ; elle relève du mystère de Dieu. On y passe de l’observance de la loi à une mise en route avec le Christ.
Le transhumanisme est-il une gnose ?
Authors: Deprez Stanislas 
Published: June 2019

Résumé Si les transhumanistes eux-mêmes ne se qualifient pas de gnostiques, ce terme leur est souvent attribué par des auteurs critiques, mais rarement explicité, comme si le rapprochement allait de soi. Est-ce si évident ? Pour répondre à cette question, il importe de définir ce qu’est la gnose, ce que nous ferons en nous référant au philosophe Hans Jonas. Ces clarifications permettront de discuter deux thèses transhumanistes qui évoquent le gnosticisme : le rejet du corps et la singularité. Cet examen montrera que si c’est à bon droit que le transhumanisme fait songer au religieux, il est difficile de considérer ce mouvement comme une gnose. Une autre hypothèse sera esquissée en conclusion : le transhumanisme pourrait être un néo-joachimisme.
