Abstract
We present results of 12CO(J = 1–0) imaging observations of NGC 4567/4568, a galaxy pair in a close encounter, with the Atacama Large Millimeter/Submillimeter Array (ALMA). For the first time, we find clear evidence of a molecular collision front with a velocity dispersion that is 16.8 ± 1.4 km s−1 at the overlapping region, owing to high spatial and velocity resolution. By integrating over the velocity width that corresponds to the molecular collision front, we find a long filamentary structure with a size of 1800 pc × 350 pc at the collision front. This filamentary molecular structure spatially coincides with a dark lane seen in the R-band image. We find four molecular clouds in the filament, each with a radius of 30 pc and mass of 106
M
⊙; the radii matching a typical value for giant molecular clouds (GMCs) and the masses corresponding to those between GMCs and giant molecular associations (GMAs). All four clouds are gravitationally bound. The molecular filamentary structure and its physical conditions are similar to the structure expected via numerical simulation. The filament could be a progenitor of super star clusters.

Published: June 2018

Mass digitization is a large undertaking for a collection. It is disruptive of routine and can challenge long-held practises. Having been through the procedure and survived, we feel we have a lot of experience to share with other institutions who are considering taking on this challenge. The changes that digitization has made to our institution are positive and the digitization a success, but that is not to say that we would not have done some things differently, were we to repeat the exercise.
In 2015 Meise Botanic Garden received a grant from the Flemish Government to upgrade its digitization infrastructure and mass digitize 1.2 million specimens from its African and Belgian Herbaria. The new infrastructure improved our workflow significantly, enabling us to digitize specimens five to ten times faster while also improving their quality.
The mass digitization part of the project was split into two parts, imaging and transcription. The contract was awarded and out-sourced to Picturae, who started imaging in May 2016 using a conveyor belt installation. Prior to starting, a significant amount of preparation was required at the herbarium. Within one year, 1.2 million specimens were imaged. The images were captured as TIFF files and stored in triplicate at The Flemish Institute for Archiving (VIAA), while smaller derived JPEG 2000 and JPEG files were generated for day-to-day use.
The second part of the project was label transcription. A third of the specimens were transcribed in-house for capturing minimal data (barcode, filing name, collector, collector number &amp; country of origin). This was partly done to reduce costs, but also allowed us to compare in-house to out-sourced transcription. Some 500,000 specimens were transcribed, either completely or partially, by Alembo (subcontracted by Picturae).The remaining 200.000 specimens from our Belgian Herbarium are being transcribed using crowdsourcing. The latter is being realized through the citizen science platform DoeDat (www.doedat.be) that was launched in November 2017.
Many lessons have been learnt with respect to implementing mass digitization, both practically and sociologically. Many of the problems encountered during the project could have been avoided by changing the workflow. The addition of extra control points during the process could have reduced problems encountered later in the data capture process. Solving these problems at a later stage was time consuming. Trying to “save money” can result in a disruptive workflow, which may lead to a number of costly errors. Mass digitization has fundamentally changed the workflow in our collections and the way in which our herbarium is managed. All images for the African and Belgian collections may be now found on our new virtual herbarium www.botanicalcollections.be.
Beyond the Museum Walls: Developing Inexpensive Discovery Trunks for k-12
Authors: Robinson Julia 
Published: June 2018

Discovery Trunks - specimen-based educational kits - use museum collections and standardized curricula to catalyze critical thinking skills through inquiry learning. Inquiry learning facilitates the development of new knowledge by examining a novel situation in light of past experience - a crucial skill for a child in today’s unpredictable world. Inquiry learning empowers students by making them stronger and more confident in their discovery and synthesis of information.
Discovery Trunks enhance learning opportunities for students, promote the parent institutions, and develop new audiences by taking the institutional mission beyond classroom walls. Such Trunks contain authentic, real world objects and inquiry lessons that align with state educational standards. Discovery Trunks encourage contemplative analytical skills, thoughtful communication, thorough exploration of a topic, and cultivate a citizenry of open-minded problem solvers. Through inquiry-based learning, we see key components of this personal investigation exemplified through student-centered, student-driven activities that connect new knowledge and prior knowledge.
This presentation will deconstruct these multidisciplinary kits and their contents to guide museum professionals to explore effective, high value, low cost materials and methods to produce and advertise educational kits to the community. Offered as an essential outreach component, these educational kits cultivate tomorrow’s thinkers, movers, and laborers in an ever-changing society.
ALERT Lessons From A Biosecurity Disaster

Published: June 2018

The Managers of Australasian Herbarium Collections (MAHC) have been working with the Plant Import Operations Branch of the Australian government Department of Agriculture and Water Resources (DAWR) to align our procedures to significantly reduce the risk of herbarium specimens being destroyed when being imported into Australia. The two groups worked together productively to bring about change and to enable the resumption of the international movement of herbarium specimens after two recent international disasters. These changes include amendments to the Biosecurity Import Conditions System (BICON) which contains the Australian government’s import conditions and onshore outcomes for herbarium specimens, changes to procedures at the border (airmail gateway facilities) where biosecurity documentation is assessed and parcels released, and updates to existing herbarium parcel labels, guidelines and supplier declaration templates. We will discuss lessons learned, as well as implications for researchers, collections managers or institutions who may be sending herbarium specimen material to Australia.
This is a presentation on beahlf of the Managers of Australasian Herbarium Collections (MAHC), a network of herbarium Collection Managers in Australia and New Zealand.
Pokémon Day at the Sternberg: Using Pop-Culture to Teach Principles of Evolution
Authors: Shelburne Edward 
Published: June 2018

Pop culture has great potential as a tool for communicating science to the public. The Sternberg Museum of Natural History (FHSM) hosted a public, all-ages outreach event utilizing Pokémon to illustrate common principles of evolution and highlighting the confluence of pop-culture and science. Pokémon is a multi-billion dollar multimedia franchise centered on the training and combat of small monsters, called Pokémon, which grow stronger and ‘evolve’ over time as they bond with their trainer. While ‘evolution’ in the Pokémon franchise is more akin to the process of metamorphosis in the real world, with weaker forms transitioning into stronger ones, principles of mutation, adaptation, and descent with modification are regularly evoked within the series. This close association between Pokémon ‘evolution’ and Darwinian evolution provides an invaluable opportunity to use a popular franchise to explain evolutionary principles through basic comparison, as well as clarifying public misperceptions of evolution by drawing attention to inaccuracies portrayed in the franchise.
Tables were placed around the Museum where fossils and illustrated graphics highlighted similarities between Pokémon designs and their extinct counterparts, while teaching the principles of adaptation, descent with modification, and island biogeography. Guests were encouraged to use self-directed learning to interact with Museum staff who explained the evolutionary principles outlined at that table and the inferences that can be made regarding the biology and ecology of the organisms the Pokémon represent. A scavenger hunt was also implemented to encourage exploration of the museum; younger guests were tasked with seeking additional Pokémon hidden throughout the museum. This interactive activity rewarded exploration of both event-specific displays and traditional exhibits with a small bag of candy upon completion. Arts-and-crafts related to Pokémon and evolution were available for very young guests. The event took place over five hours on a Saturday; normal admission fees were required. Principles learned from this Pokémon Day event can be used by the FHSM and other institutions to further refine engaging and informative public outreach events in the future, utilizing different pop-culture franchises to teach scientific principles to the public.

Published: June 2018

In 2017 NSF funded “oVert (openVertebrate): Open Exploration of Vertebrate Diversity in 3D,” which is the first Thematic Collections Network devoted entirely to vertebrate morphological specimens. The primary goal of oVert is to generate and serve high-resolution digital three-dimensional data for internal anatomy across vertebrate diversity. oVert will CT-scan &gt;20,000 fluid-preserved specimens representing &gt;80% of the living genera of vertebrates, providing broad coverage for exploration and research on all major groups of vertebrates. Contrast-enhanced scans will be generated to reveal soft tissues and organs for a majority of the living vertebrate families. This collection of digital imagery and three-dimensional volumes will be open for exploration, download, and use. These new media will provide unprecedented global access to valuable morphological data of specimens in US collections.oVert is developing best practices and guidelines for high-throughput CT-scanning, including efficient workflows, preferred resolutions, and archival formats that optimize the variety of downstream applications.
Using the Integrated Digitized Biocollections (iDigBio) API, we have developed a workflow where people uploading media files to MorphoSource can search for and import metadata for specimens directly from iDigBio. Via a Rich Site Summary (RSS) feed from MorphoSource, Audubon Core data describing media files for a given scientific collection can be retrieved and integrated into institutional IPT and databases. Such data migration of large files requires attention to detail and the development of data workflows that ensure correct specimen mapping at all steps. The RSS feed from MorphoSource will also consolidate usage information for media files from specimens in each scientific collection for reporting. Additional goals of the project are to provide information vital to the creation of collection best practices for imaging permissions/copyright. A status report and update on best practices will be presented.
Cretaceous World TCN: Digitizing the Western Interior Seaway at the Yale Peabody Museum

Published: June 2018

Yale Peabody Museum (YPM) is a partner in the Western Interior Seaway Thematic Collections Network (TCN), along with the University of Kansas (lead) and seven other institutions (National Science Foundation Award # DBI-1601884). This project seeks to digitize the fossil organisms of the Western Interior Seaway, a shallow sea that covered inland North America from 100 to 65 million years ago. The resultant data will be a resource for K-16 education and will enable scientists to answer fundamental questions about the changing environment of a marine ecosystem during a key time in the history of life. The data generated will be ideal for use with an assortment of modern quantitative tools like paleoecological niche modeling (PaleoENM) and will help improve paleoclimate and paleoceanographic models.
Less than two years into this three-year project, the YPM has digitized nearly 70,000 Cretaceous fossils from the seaway. Specimens are georeferenced and most have multiple images. To achieve project goals, we have overcome obstacles of digitizing multi-specimen concretions and foraminifera microslides by developing high-throughput digitization workflows that incorporate the open-source Inselect program and scripts to streamline image naming, image formatting, and uploading to our Axiell EMu collection management system.
To facilitate use of the data in K-16 environments, an easy to use collections interface has been built using the iDigPaleo platform (idigpaleo.org). Cretaceous World (cretaceousworld.org) pulls data from iDigBio for all Cretaceous World TCN providers. Students can browse specimens using filters, rather than entering specific search terms. Navigation is simplified using common names harvested from the Encyclopedia of Life. Specimens are displayed as images accompanied by collection and locality data and plotted on a map. Registration provides access to tools supporting annotation, measurement, specimen record commenting, and social media sharing. Images can be curated as galleries and used for education. This includes sharing of galleries between students and teachers and PDF or PowerPoint exports.
Fifty-eight 3D models of vertebrates and invertebrates have been placed on morphosource.org and will be made available via a 3D embedded viewer on cretaceousworld.org for use in K-16 education. Undergraduate students from Dartmouth, Oberlin, Southern Connecticut State University, and Yale, have participated in the project and served as mentors for high school interns. These interns, recruited from the Peabody EVOLUTIONS afterschool program, gained first-hand experience in collections-based research, digitization, and imaging techniques, while learning about the science of paleontology and the process of curating museum collections, and researching and reconstructing food webs in this fascinating ancient ecosystem.
Storing, Maintaining and Mobilizing Botswana National Museum’s Entomology Digital Collections: The GBIF/BID Approach
Authors: Rapalai Boikhutso Lerato 
Published: June 2018

The Botswana National Museum is mandated to protect, preserve and promote Botswana’s cultural and natural heritage for sustainable utilization thereof by collecting, researching, conserving and exhibiting for public education and appreciation. The Entomology Section of the museum is aiming towards becoming the national center for entomology collections as well as contributing to the monitoring and enhancement of natural heritage sites in Botswana. The Botswana National Museum entomology collection was assembled over more than three decades by a succession of collectors, curators and technical officers. Specimens are carefully prepared and preserved, labelled with field data, sorted and safely stored. The collection is preserved as wet (ethanol preserved) or as dry pinned specimens in drawers. This collection is invaluable for reference, research, baseline data and educational purposes.
As a way of mobilizing insect biodiversity data and making it available online for conservation efforts and decision making processes, in 2016 the Botswana National Museum collaborated with five other African states to implement the Biodiversity Information for Development (BID) and Global Biodiversity Information Facility (GBIF) funded African Insect Atlas’ Project (https://www.gbif.org/project/82632/african-insect-atlas). This collaborative project was initiated to move biodiversity knowledge out of select insect collections into the hands of a new generation of global biodiversity researchers interested in direct outcomes. To date, the Botswana National Museum has been instrumental through the efforts of this project in storing, maintaining and mobilizing insect digital collections and making the data available online through the GBIF Platform.
Turning a Recently-Donated Mineral Collection into a Multifaceted Learning Experience
Authors: Miller-Camp Jess 
Published: June 2018

The Schultz Collection is a group of over 1500 display-quality minerals which was donated to the University of California, Riverside Earth Sciences Museum last year. The collector was very systematic in assembling it, emphasizing a breadth of taxonomy, crystal forms, and uniqueness. A broad sample of mineral classes are present. Mineral species with a wide variety of forms, such as calcite, are represented by numerous diverse samples. Some of the species and gem forms, such as charoite, are only found in one location worldwide. In strictly monetary terms, it has been appraised at over $113,000 (USD; $155,000 NZD). But the true value of this collection lies in the excellent learning opportunities it has proven to hold for students, professionals, and visitors alike.
Unlike nearly all collections assembled by enthusiasts, Henry Schultz made sure his collection was both well-labelled and catalogued, with locality information available for nearly all. Coupled with the various needs it requires and the small number of specimens compared to other collections already in our possession, this makes it an ideal source of many student projects. No institution in the Inland Empire of Southern California has a formal museum studies program that includes natural history. The creation of a volunteer program in the museum and an interdepartmental Natural History Museum Club in the Natural History Collections Care Network (NHCCN) are steps towards rectifying this.
Projects run the gamut across most museum studies activities. Curation and registrar-work includes: handwriting new University of California, Riverside (UCR)-specific labels with archival ink as a group activity during club meetings; turning Schultz’s spreadsheet into a relational database and filling in information gaps when possible; and rehousing all specimens in acid-free trays. An additional outcome is the creation of a time-saving relational database of the Dana classification system (shareable upon request). Conservation and preparation include: cleaning dust and packing material off of specimens; attempting to halt the pyrite disease in one specimen; and discussing the special care needs for certain minerals. Exhibit design and fabrication include: brainstorming exhibit sections; selecting specimens for display; and exhibit installation. Exhibit sections will in part be used to give a behind-the-scenes peek, educating the public on museum studies, with one section devoted to care of minerals and another discussing how much work students and staff have put into fully processing the collection. Education and outreach include progress updates on social media, which have a reach comparable to those discussing departmental research.
The structural validity and measurement invariance across gender of the Brief Corporate Entrepreneurship Assessment Instrument
Authors: Steyn Renier , De Bruin G. P. 
Published: June 2018

Background: Corporate entrepreneurial activity and innovation are presented as essential elements of organisational success, and gender diversity is often seen as an important variable in this context. The efficient measurement of these variables is essential to the management thereof. It is within this context that the Brief Corporate Entrepreneurship Assessment Instrument (BCEAI) was developed. Shorter instruments seem to be favoured by researchers and practitioners alike. However, little is known about the psychometric properties of the BCEAI, particularly regarding measurement invariance. Aim: This study seeks to address the structural validity and measurement invariance for the BCEAI applied for men and women. The objective was to establish the utility of the instrument within the South African context, with specific emphasis on cross-gender comparisons. Setting: Medium to large South African organisations, with more than 60 employees, were targeted for inclusion in the study. Once organisations indicated their willingness to participate, 60 employees per organisation were randomly selected to participate in the study. Methods: Data on the BCEAI were captured and pairwise multi-group confirmatory factor analyses with robust maximum likelihood estimation were used to examine four levels of measurement invariance, as well as the equivalence of latent means pertaining to male and female respondents. Results: Data were collected from 3180 employees representing 52 SouthAfrican organisations. The results support the structural validity of the BCEAI and demonstrate strict measurement invariance for the BCEAI across gender. Equivalence of latent means across gender was also supported. Conclusion: These results reveal that the BCEAI mirrors the structure of the original instrument in the South African context and that BCEAI yields psychometrically equivalent scores among employees of both genders. Researchers and practitioners can therefore use the BCEAI with the knowledge that its theoretical structure is sound and can apply it with confidence when comparing male and female employees in the workplace.

Sunflower is considered a temperate zone crop but it can perform well under varying climate conditions. In this context, the aim of this study was to evaluate the growth of ornamental sunflower cultivars for cutting in two growing seasons in semiarid conditions. Sunflowers cultivars were sown in a randomized complete design in a split plot system, with four blocks. Six cultivars were evaluated (‘Bonito de outono sortido’, ‘Sol noturno’, ‘Sol vermelho’, ‘Jardim amarelo alto’, ‘Sunflower F1 sunbright supreme’ and ‘Sunflower F1 vincents choice’) in the main plots and two growing seasons in the subplots (GS1 – hot weather and GS2 – mild weather). Plant emergence percentage, plant height, stem diameter, number of leaves and internal inflorescence diameter were significant affected both by sunflowers cultivars and growing seasons. Emergence speed index and external inflorescence diameter were significantly affected by the interaction of cultivars and growing seasons. The obtained results indicated ‘Sol vermelho’ for cultivation in growing seasons with mild temperatures (GS2) and 'Sunflower F1 vincents choice' recommended for both growing seasons with mild climatic (GS2) and in warmer conditions (GS1). Although all other cultivars studied have not been indicated immediately, they may be considered for cultivation, but more studies are necessary for better acclimatization.
