Available in PDF, EPUB and Kindle. Book excerpt: A Choice Outstanding Academic Title for 2013While the success of higher education and student affairs is predicated on understanding the students we serve, the reality is, where the Native American population is concerned, that this knowledge is generally lacking. This lack may be attributed to this population’s invisibility within the academy – it is often excluded from institutional data and reporting, and frequently noted as not statistically significant – and its relegation to what is referred to as the “American Indian research asterisk.”The purpose of this book is to move beyond the asterisk in an effort to better understand Native students, challenge the status quo, and provide an informed base for leaders in student and academic affairs, and administrators concerned with the success of students on their campuses.The authors of this book share their understanding of Native epistemologies, culture, and social structures, offering student affairs professionals and institutions a richer array of options, resources, and culturally-relevant and inclusive models to better serve this population. The book begins by providing insights into Native student experiences, presenting the first-year experience from a Native perspective, illustrating the role of a Native living/learning community in student retention, and discussing the importance of incorporating culture into student programming for Native students as well as the role of Native fraternities and sororities.The authors then consider administrative issues, such as the importance of outreach to tribal nations, the role of Tribal Colleges and Universities and opportunities for collaborations, and the development of Native American Student Services Units..The book concludes with recommendations for how institutions can better serve Native students in graduate programs, the role that Indigenous faculty play in student success, and how professional associations can assist student affairs professionals with fulfilling their role of supporting the success of Native American students, staff, and faculty. This book moves beyond the asterisk to provide important insights from Native American higher education leaders and non-Native practitioners who have made Native students a priority in their work.While predominantly addressed to the student affairs profession – providing an understanding of the needs of the Native students it serves, describing the multi-faceted and unique issues, characteristics and experiences of this population, and sharing proven approaches to developing appropriate services – it also covers issues of broader administrative concern, such as collaboration with tribal colleges; as well academic issues, such as graduate and professional education. The book covers new material, as well as expanding on topics previously addressed in the literature, including Native American Greek organizations, incorporating Native culture into student programming, and the role of Native American Special Advisors. The contributors are themselves products of colleges and universities where Native students are too often invisible, and who succeeded despite the odds. Their insights and the examples they provide add richness to this book. It will provide a catalyst for new higher education practices that lead to direct, and increased support for, Native Americans and others who are working to remove the Native American asterisk from research and practice.

Download or read book Trans written by Jack Halberstam and published by Univ of California Press. This book was released on 2018-01-24 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title is part of American Studies Now and available as an e-book first. Visit ucpress.edu/go/americanstudiesnow to learn more. In the last decade, public discussions of transgender issues have increased exponentially. However, with this increased visibility has come not just power, but regulation, both in favor of and against trans people. What was once regarded as an unusual or even unfortunate disorder has become an accepted articulation of gendered embodiment as well as a new site for political activism and political recognition. What happened in the last few decades to prompt such an extensive rethinking of our understanding of gendered embodiment? How did a stigmatized identity become so central to U.S. and European articulations of self? And how have people responded to the new definitions and understanding of sex and the gendered body? In Trans*, Jack Halberstam explores these recent shifts in the meaning of the gendered body and representation, and explores the possibilities of a nongendered, gender-optional, or gender-queer future.

Download or read book Switching to VoIP written by Theodore Wallingford and published by "O'Reilly Media, Inc.". This book was released on 2005 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it's revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP. VoIP has advanced Internet-based telephony to a viable solution, piquing the interest of companies small and large. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. But the real enterprise turn-on is how VoIP empowersbusinesses to mold and customize telecom and datacom solutions using a single, cohesive networking platform. These business drivers are so compelling that legacy telephony is going the way of the dinosaur, yielding to Voice over IP as the dominant enterprise communications paradigm. Developed from real-world experience by a senior developer, O'Reilly's Switching to VoIP provides solutions for the most common VoIP migration challenges. So if you're a network professional who is migrating from a traditional telephony system to a modern, feature-rich network, this book is a must-have. You'lldiscover the strengths and weaknesses of circuit-switched and packet-switched networks, how VoIP systems impact network infrastructure, as well as solutions for common challenges involved with IP voice migrations. Among the challenges discussed and projects presented: building a softPBX configuring IP phones ensuring quality of service scalability standards-compliance topological considerations coordinating a complete system ?switchover? migrating applications like voicemail and directoryservices retro-interfacing to traditional telephony supporting mobile users security and survivability dealing with the challenges of NAT To help you grasp the core principles at work, Switching to VoIP uses a combination of strategy and hands-on how-to that introduce VoIP routers and media gateways, various makes of IP telephone equipment, legacy analog phones, IPTables and Linux firewalls, and the Asterisk open source PBX software by Digium.You'll learn how to build an IP-based or legacy-compatible phone system and voicemail system complete with e-mail integration while becoming familiar with VoIP protocols and devices. Switching to VoIP remains vendor-neutral and advocates standards, not brands. Some of the standards explored include: SIP H.323, SCCP, and IAX Voice codecs 802.3af Type of Service, IP precedence, DiffServ, and RSVP 802.1a/b/g WLAN If VoIP has your attention, like so many others, then Switching to VoIP will help you build your own system, install it, and begin making calls.
