The basic objective of Unified Engineering is to give a solid understanding of the fundamental disciplines of aerospace engineering, as well as their interrelationships and applications. These disciplines are Materials and Structures (M); Computers and Programming (C); Fluid Mechanics (F); Thermodynamics (T); Propulsion (P); and Signals and Systems (S). In choosing to teach these subjects in a unified manner, the instructors seek to explain the common intellectual threads in these disciplines, as well as their combined application to solve engineering Systems Problems (SP). Throughout the year, the instructors emphasize the connections among the disciplines.

Software Carpentry lesson on how to use the shell to navigate the filesystem and write simple loops and scripts. The Unix shell has been around longer than most of its users have been alive. It has survived so long because it’s a power tool that allows people to do complex things with just a few keystrokes. More importantly, it helps them combine existing programs in new ways and automate repetitive tasks so they aren’t typing the same things over and over again. Use of the shell is fundamental to using a wide range of other powerful tools and computing resources (including “high-performance computing” supercomputers). These lessons will start you on a path towards using these resources effectively.

This guide is designed to help those who use SciVal, a research analytics tool from Elsevier that sources bibliographic data from Scopus, to source and apply bibliometrics in academic institutions. It was originally devised in February 2018 by Dr. Ian Rowlands of King’s College London as a guide for his university, which makes SciVal widely available to its staff. King’s does this because it believes that bibliometric data are best used in context by specialists in the field. A small group of LIS-Bibliometrics committee members reviewed and revised the King’s guide to make it more applicable to a wider audience. SciVal is a continually updated source and so feedback is always welcome at LISBibliometrics@jiscmail.ac.uk. LIS-Bibliometrics is keen that bibliometric data should be used carefully and responsibly and this requires an understanding of the strengths and limitations of the indicators that SciVal publishes.

The purpose of this Guide is to help researchers and professional services staff to make the most meaningful use of SciVal. It includes some important `inside track’ insights and practical tips that may not be found elsewhere. The scope and coverage limitations of SciVal are fairly widely understood and serve as a reminder that these metrics are not appropriate in fields where scholarly communication takes place mainly outside of the journals and conference literature. This is one of the many judgment calls that need to be made when putting bibliometric data into their proper context. One of the most useful features of SciVal is the ability to drill down in detail using various filters. This allows a user to define a set of publications accurately, but that may mean generating top level measures that are based on small samples with considerable variance. Bibliometrics distributions are often highly skewed, where even apparently simple concepts like the `average’ can be problematic. So one objective of this Guide is to set out some advice on sample sizes and broad confidence intervals, to avoid over-interpreting the headline data. Bibliometric indicators should always be used in combination, not in isolation, because each can only offer partial insights. They should also be used in a 'variable geometry' along with other quantitative and qualitative indicators, including expert judgments and non-publication metrics, such as grants or awards, to flesh out the picture.

This lesson is part of the Software Carpentry workshops that teach how to use version control with Git. Wolfman and Dracula have been hired by Universal Missions (a space services spinoff from Euphoric State University) to investigate if it is possible to send their next planetary lander to Mars. They want to be able to work on the plans at the same time, but they have run into problems doing this in the past. If they take turns, each one will spend a lot of time waiting for the other to finish, but if they work on their own copies and email changes back and forth things will be lost, overwritten, or duplicated. A colleague suggests using version control to manage their work. Version control is better than mailing files back and forth: Nothing that is committed to version control is ever lost, unless you work really, really hard at it. Since all old versions of files are saved, it’s always possible to go back in time to see exactly who wrote what on a particular day, or what version of a program was used to generate a particular set of results. As we have this record of who made what changes when, we know who to ask if we have questions later on, and, if needed, revert to a previous version, much like the “undo” feature in an editor. When several people collaborate in the same project, it’s possible to accidentally overlook or overwrite someone’s changes. The version control system automatically notifies users whenever there’s a conflict between one person’s work and another’s. Teams are not the only ones to benefit from version control: lone researchers can benefit immensely. Keeping a record of what was changed, when, and why is extremely useful for all researchers if they ever need to come back to the project later on (e.g., a year later, when memory has faded). Version control is the lab notebook of the digital world: it’s what professionals use to keep track of what they’ve done and to collaborate with other people. Every large software development project relies on it, and most programmers use it for their small jobs as well. And it isn’t just for software: books, papers, small data sets, and anything that changes over time or needs to be shared can and should be stored in a version control system.

This course focuses on a number of qualitative social science methods that can be productively used in media studies research including interviewing, participant observation, focus groups, cultural probes, visual sociology, and ethnography. The emphasis will primarily be on understanding and learning concrete techniques that can be evaluated for their usefulness in any given project and utilized as needed. Data organization and analysis will be addressed. Several advanced critical thematics will also be covered, including ethics, reciprocity, “studying up,” and risk. The course will be taught via a combination of lectures, class discussions, group exercises, and assignments. This course requires a willingness to work hands-on with learning various social science methods and a commitment to the preparation for such (including reading, discussion, and reflection).
