Journal policy on research data and code availability is an important part of the ongoing shift toward publishing reproducible computational science. This article extends the literature by studying journal data sharing policies by year (for both 2011 and 2012) for a referent set of 170 journals. We make a further contribution by evaluating code sharing policies, supplemental materials policies, and open access status for these 170 journals for each of 2011 and 2012. We build a predictive model of open data and code policy adoption as a function of impact factor and publisher and find higher impact journals more likely to have open data and code policies and scientific societies more likely to have open data and code policies than commercial publishers. We also find open data policies tend to lead open code policies, and we find no relationship between open data and code policies and either supplemental material policies or open access journal status. Of the journals in this study, 38% had a data policy, 22% had a code policy, and 66% had a supplemental materials policy as of June 2012. This reflects a striking one year increase of 16% in the number of data policies, a 30% increase in code policies, and a 7% increase in the number of supplemental materials policies. We introduce a new dataset to the community that categorizes data and code sharing, supplemental materials, and open access policies in 2011 and 2012 for these 170 journals.

Modern economies rely heavily on financial intermediaries to channel funds between borrowers and lenders. In this issue, the role of traditional banking is outlined and a parallel system—shadow banking—is explored.

The article presents the evaluation of the training programme for secondary school principals conducted in the period between 2006 and 2009. A mixed method approach was used to conduct the summative evaluation with 28 graduate participants. For the impact evaluation, 15 of the graduates were interviewed three years after the programme was completed. The quantitative data was analyzed using means and standard deviation. The findings revealed that participants gained technical and relational skills but responses were less favourable in relation to cognitive or conceptual skills, while the support from lecturers and workplaces was strong but less favourable from the central ministry. There was a positive impact on participants’ performance during the period of training, especially in the areas of confidence, collegiality and overall leadership. For the impact evaluation, graduates credited the programme for their promotion to become principals, vice principals, senior teachers or give added responsibilities. They identified areas to be enhanced for any further programme to include school law, financial management, policy development and interpretation, and conflict management and relational skills. The main recommendation is that for any further programme for the training of principals should be guided by the findings of the evaluation.

One of the greatest areas of potential for open educational resources (OER) is the opportunity for improved representation and coverage of identities that often go erased or poorly addressed in educational materials. Information about, by, and for trans and gender diverse people is one such topic. With knowledge and intention, those involved in the creation, adaptation, and use of OER can find and incorporate materials that center trans and gender diverse people. Doing this is essential for supporting trans and gender diverse students and educating everyone about these identities. This resource is a guide on how to make OER more inclusive and representative of trans and gender diverse people. It is intended to be easily incorporated into a scholarly communications course, while also being valuable to faculty and others interested in learning about the topic and how to make changes to their own course materials.

In 1862, Congress passed and President Lincoln signed the Pacific Railroad Bill, which granted public land and funds to build a transcontinental railroad. The Central Pacific Railroad would lay tracks from California heading east, and the Union Pacific Railroad would lay tracks from the Missouri River west. The photograph taken in Placer County, "Grading the Central Pacific Railroad," shows some of the construction. Work on the railroad was physically difficult and at times dangerous, and attracting workers was a challenge. The majority of the Central Pacific's laborers were Chinese. A Chinese worker is shown in the image "Heading (top cut) of East Portal, Tunnel No. 8." Both railroad companies actively recruited Chinese laborers because they were regarded as hard workers and were willing to accept a lower wage than white workers, mostly Irish immigrants. As construction progressed, the Central Pacific and the Union Pacific competed to see which could lay the most track each day. A photograph of a sign near Promontory Park, Utah, commemorates the day that Central Pacific crews laid an unprecedented 10 miles of track. The meeting of the two sets of tracks ? the "gold spike" ceremony ? took place on May 10, 1869. Several photographs and drawings depict this historic moment. Now the country was connected as never before: a journey between San Francisco and New York that previously took up to six months now took only days. The photograph "High Bridge in Loop," from Views from a Trip to California, shows a train passing quickly through a mountain pass. The transcontinental railroad allowed people to travel more, farther, and in pleasant conditions, as reflected in the photograph "Commissary Car, 'Elkhorn Club.'" The photograph "Knights of Pythias at the Santa Fe Railway Station, Anaheim" shows an example of the popularity of trains. Even as the transcontinental railroad brought the new country together, it brought change to the world of Native Americans. The tracks ran through a number of tribal territories, bringing into conflict cultures that held very different views of the land and how it might be used and lived on. The painting The First Train, by Herbert Schuyler, depicts three Indians pointing past their encampment at a train in the far distance. The railroad also brought an increasing number of European Americans west. One consequence of this influx was the depletion of the buffalo herds, a major food source for Plains Indians. European Americans would often shoot buffalo for sport from the train; by 1880, the buffalo were mostly gone and Plains Indians had been gathered onto reservations. Millions of acres of open grassland were being settled by the people moving west. Eventually, much of this land became the farmland that fed a growing nation. The transcontinental railroad opened up the West to the rest of the country, even if they never made the trip themselves. A Currier & Ives hand-colored lithograph depicts a train running along the Truckee River in Northern California. The San Francisco publishing firm of Lawrence & Houseworth hired photographers and published photographic tourist catalogs containing views of the West, which they sold commercially. The railroad took hold in popular culture, as shown by sheet music for the song "New Express Galop [sic]." There was even a railroad board game illustrating "Railroads Between New York and San Francisco, California, with Scenes on the Way."

An interactive applet and associated web page showing how to find the area and perimeter of a trapezoid from the coordinates of its vertices. The trapezoid can be either parallel to the axes or rotated. The grid and coordinates can be turned on and off. The area and perimeter calculation can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts. The web page has a full description of the method for determining area and perimeter, a worked example and has links to other pages relating to coordinate geometry. Applet can be enlarged to full screen size for use with a classroom projector.

U.S. taxpayers expect the government to be a careful steward of taxpayer money. The October 2017 issue of Page One Economics: Focus on Finance explains how the Treasury Offset Program recovers taxpayer money from people who have received government benefits in error or by fraud and also recovers delinquent child support.

An interactive applet and associated web page that introduce the concept of a triangle. The applet shows a triangle where the user can drag the vertices to reshape it. As it is being dragged a base and altitude are shown continuously changing. Demonstrates that the altitude may require the base to be extended. The text on the page lists the properties of a triangle and lists the various triangle types, with links to a definition of each. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

An interactive applet and associated web page that demonstrate that in similar triangles, the ratio of their areas is the square of the ratio of the sides. As you drag one triangle to resize it, it remains similar to another and the ratios of sides and areas is calculated as you drag. One can be seen to be the square of the other at all times. A slight 'snap-to' effect allows easy selection of integer ratios (2:4 etc). Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference interactive geometry reference book project at http://www.mathopenref.com.

This video profiles glaciologist Lonnie Thompson and his research into tropical mountain glaciers as a way to understand climate history. Beginning in the 1970s, Thompson recognized that tropical ice cores contain information relating to tropical climate phenomena, including El NiÃo events and monsoons. These phenomena are not archived in ice from polar regions. Thompson explains that his archive of ice cores is full of clues that, taken together with records collected from around the world, can help scientists create a timeline that tells Earth's climate story.
