Please Don’t Go - Increasing Women’s Participation in Open Source Software Bianca Trinkenreich Northern of Arizona University Flagstaff, AZ, USA [email protected] Abstract—Women represent less than 24% of the software the development of the community with norms and values development industry and suffer from various types of prejudice consistent with their own vision [12], focusing on the first and biases. In Open Source Software projects, despite a variety social experiences through programs such as mentorships [13], of efforts to increase diversity and multi-gendered participation, women are even more underrepresented (less than 10%). My and fixing the gender-bias issues in non-inclusive tools and research focuses on answering the question: How can OSS infrastructure [14]. Some strategies that are discouraged by communities increase women’s participation in OSS projects? the literature include setting quotas for women. Just increasing I will identify the different OSS career pathways, and develop the proportion of women can lead to questioning stereotypes a holistic view of women’s motivations to join or leave OSS, and decisions to simply re-classify types of work that are cur- along with their definitions of success. Based on this empirical investigation, I will work together with the Linux Foundation rently packaged in masculine-feminine stereotyped specialties. to design attraction and retention strategies focused on women. Another discouraged strategy is related to coding schools that Before and after implementing the strategies, I will conduct train women in specialties where they are already represented. empirical studies to evaluate the state of the practice and These schools might perpetuate the disadvantage of women understand the implications of the strategies. -

Open Courseware and Developing Countries: Building a Community
Open Courseware and Developing Countries: Building a Community This is the report of The Forum on the Impact of Open Courseware for Higher Education in Developing Countries, convened in Paris by UNESCO 1-3 July 2002, with the support of the William and Flora Hewlett Foundation and organizational assistance from the Western Cooperative for Educational Telecommunications, WCET. Participants mapped a collaborative course, involving colleges and universities from around the world, for the productive and creative use of openly shared educational resources. In advance comments, summarized in an appendix to this report, they provided insights on the potentials and complex issues involved. This report was prepared by John Witherspoon.

This emerging consortium was organized to evaluate, adapt, use, and develop open resources for its members’ many cultures and diverse languages. -
From Openness to Permeability: Reframing Open Education in Terms of Positive Liberty in the Enactment of Academic Practices Oliver, M
From openness to permeability: reframing open education in terms of positive liberty in the enactment of academic practices Oliver, M. Learning, Media and Technology, 40(3):365-384. 03 Jul 2015. DOI:10.1080/17439884.2015.1029940 Abstract This paper explores the idea of open education, focusing specifically on the concept of openness. Previous discussions of open education are reviewed, using Knox’s discussion of “unfreedoms” as a critical lens. Contrasts are then drawn with the concept of ‘flexibility’, to illustrate ways in which openness could be developed. This leads to consideration of ideas from sociomaterial theory, focusing on networks and boundaries. A case study is then used to illustrate how these new developments play out empirically. The discussion then elaborates this in terms of ideas about mobility and fluidity. The paper concludes by arguing that the simplistic binary implied by ‘openness’ is largely irrelevant to the academic practices of teachers and learners. It is proposed that, instead, it should be replaced by a version that recognises the way individuals use infrastructures in pursuit of positive liberty. Such an alternative would help account for the various ways in which Universities are permeated by the personal, and vice versa. Introduction The concept of ‘open education’ has grown in importance and visibility, but the concept of openness is, arguably, under-developed within the field of learning technology. In this paper, the concept of open education will be reviewed; compared to wider discussions about flexibility in Higher Education; and illustrated using data from a study exploring contemporary academic practice. Closing education Although the concept and practice of ‘open education’ have grown in prominence over the last decade, debates continue to over-simplify ideas of openness in several important ways. -

Android – the First Truly Open and Complete Platform for Mobile Devices
Android – the first truly open and complete platform for mobile devices KNOW-HOW # 50 Android is a new open-source platform for mobile phones. With its solid Linux foundation, a very business-friendly open-source license and an easy-to-use Java programming model, it provides a perfect basis for mobile applications – and beyond. As part of the Open Handset Alliance that guides Android‘s evolution, Noser Engineering AG contributed functionality to the core platform. «Android is the first truly open and comprehensive platform for mobile devices. It includes an operating system, user-interface and applications – all of the software to run a mobile phone, but without the proprietary obstacles that have hindered mobile innovation. We have developed Android in cooperation with the Open Handset Alliance, which consists of more than 30 technology and mobile leaders including Motorola, Qualcomm, HTC and T-Mobile. Through deep partnerships with carriers, device manufacturers, developers, and others, we hope to enable an open ecosystem for the mobile world by creating a standard, open mobile software platform. We think the result will ultimately be a better and faster pace for innovation that will give mobile customers unforeseen applications and capabilities.» Andy Rubin, Director of Mobile Platforms at Google, official Google Blog entry 11/5/2007 we know how The project As part of the Open Handset Alliance and on behalf of Google, Noser Engineering AG contributed the larger part of the so-called «Android core libraries». These are basically a set of libraries that provide most of the functionality typically found in desktop implementations of the Java programming language, but adapted to and optimized for a mobile device. -
Android (Operating System) 10.1 Introduction: Android Is a Mobile
Page 1 of 9 Android (operating system) 10.1 Introduction: Android is a mobile operating system (OS) based on the Linux kernel and currently developed by Google. With a user interface based on direct manipulation, Android is designed primarily for touchscreen mobile devices such as smartphones and tablet computers, with specialized user interfaces for televisions (Android TV), cars (Android Auto), and wrist watches (Android Wear). The OS uses touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to manipulate on-screen objects, and a virtual keyboard. Despite being primarily designed for touchscreen input, it also has been used in game consoles, digital cameras, and other electronics. Android is the most popular mobile OS. As of 2013, Android devices sell more than Windows, iOS, and Mac OS devices combined,[14][15][16][17] with sales in 2012, 2013 and 2014[18] close to the installed base of all PCs.[19] As of July 2013 the Google Play store has had over 1 million Android apps published, and over 50 billion apps downloaded.[20] A developer survey conducted in April–May 2013 found that 71% of mobile developers develop for Android.[21] At Google I/O 2014, the company revealed that there were over 1 billion active monthly Android users (that have been active for 30 days), up from 538 million in June 2013.[22] Android's source code is released by Google under open source licenses, although most Android devices ultimately ship with a combination of open source and proprietary software.[3] -
