Kvinnliga nätverk - ett sätt att göra skillnad? : En fallstudie på nätverket Q80 och dess mentor programWennberg, Amanda, Stenmark, Sofie January 2011 (has links)
Sweden is known to be one of the world’s most equal countries. Nevertheless, out of Sweden’s 262 listed companies, only seven of them has a female president, which is equal to 3,4 percent. To counteract these numbers there are several possibilities. One arrangement that is highly controversial is affirmative actions. But there are other options, for instance more and more female networks are starting to rise and many of them also offers a mentoring program where the mentee gets the opportunity to learn from someone with more experience. The purpose of this study is to examine what difference the female network Q80, with focus on its mentoring program, is doing for the mentee. As an underlying purpose the study is also examining what visions and attitudes the management and the mentors is communicating within Q80. The focus is mainly on the visions of Q80, menas mentors and business exceeding mentorship. A survey has been carried out among mentees from three different seats of mentoring programs where they have answered 19 different questions regarding their time as a mentee. Furthermore interviews have taken place with the management of Q80 and two mentors. The results are analyzed based on theories about gender, women in management, leadership, mentoring program and organizational structure. The result shows that Q80i as a source of inspiration and a support for the category of "career women" with its core mission to strengthen the participation of individuals on a personal level more than to work to even out the gap in the Swedish labor market. In terms of what the mentee get out of the participation in the Q80's net working and mentoring program, the biggest difference has been shown to be personal development.

Tool Life of Various Tool Materials When Friction Spot Welding DP980 SteelRidges, Christopher Shane 10 March 2011 (has links) (PDF)
In this study, friction spot welding was used to join DP980 steel sheet. Four different ultra-hard tool materials were used with the objective of determining which tool material produced the highest number of acceptable-strength welds. Three of the tools were composed of various mixtures of polycrystalline cubic Boron Nitride (PCBN), Tungsten, and Rhenium. These materials are referred to herein as Q60, Q70, and Q80, the "Qxx" designation denoting the percentage of the volume of the tool material composed of PCBN. The fourth tool tested was composed entirely of PCBN. The Q70 tool produced approximately 1100 welds of acceptable strength before average weld strength decreased below the acceptable value, and the Q60 tool produced approximately 600 welds of acceptable strength. The Q80 material did not produce any welds with strengths above the acceptable value. However, Q80 produced the greatest number of welds of consistent strength. The PCBN tool, being the hardest, also did not produce any welds of acceptable strength, and failed at 257 welds. This failure is presumed to be a result of a tool/parameter mismatch which caused excessive loads on the tool. This research revealed that the weld parameters and tool materials used in this study will not generally provide for feasibility of implementation in industry. Further advances in weld parameter selection, tool geometry, and tool materials will be necessary in order to make friction spot joining of high strength steels an economically viable option.
