Kvinnliga nätverk - ett sätt att göra skillnad? : En fallstudie på nätverket Q80 och dess mentor program

Wennberg, 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 Steel

Ridges, 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.
