  • A recent bottleneck of Y chromosome diversity coincides with a global change in culture.

    • It is commonly thought that human genetic diversity in non-African populations was shaped primarily by an out-of-Africa dispersal 50-100 thousand yr ago (kya). Here, we present a study of 456 geographically diverse high-coverage Y chromosome sequences, including 299 newly reported samples. Applying ancient DNA calibration, we date the Y-chromosomal most recent common ancestor (MRCA) in Africa at 254 (95% CI 192-307) kya and detect a cluster of major non-African founder haplogroups in a narrow time interval at 47-52 kya, consistent with a rapid initial colonization model of Eurasia and Oceania after the out-of-Africa bottleneck. In contrast to demographic reconstructions based on mtDNA, we infer a second strong bottleneck in Y-chromosome lineages dating to the last 10 ky. We hypothesize that this bottleneck is caused by cultural changes affecting variance of reproductive success among males.

  • European consensus conference on diagnosis and treatment of germ cell cancer: A report of the second meeting of the European Germ Cell Cancer Consensus Group (EGCCCG): Part I
  • 2008
  • Ingår i: European Urology. - : Elsevier BV. - 1873-7560 .- 0302-2838. ; 53:3, s. 478-496
  • Forskningsöversikt (refereegranskat)abstract
    • Objectives: The first consensus report presented by the European Germ Cell Cancer Consensus Group (EGCCCG) in the year 2004 has found widespread approval by many colleagues throughout the world. In November 2006, the group met a second time under the auspices of the Department of Urology of the Amsterdam Medical Center, Amsterdam, The Netherlands. Methods: Medical oncologists, urological surgeons, radiation oncologists as well as pathologists from several European countries reviewed and discussed the data that had emerged since the 2002 conference, and incorporated the new data into updated and revised guidelines. As for the first meeting, the methodology of evidence-based medicine (EBM) was applied. The results of the discussion were compiled by the writing committee. All participants have agreed to this final update. Results: The first part of the consensus paper describes the clinical presentation of the primary tumor, its treatment, the importance and treatment of testicular intraepithelial neoplasia (TIN), histological classification, staging and prognostic factors, and treatment of stage I seminoma and non-seminoma. Conclusions: Whereas the vast majority of the recommendations made in 2004 remain valid 3 yr later, refinements in the treatment of early- and advanced-stage testicular cancer have emerged from clinical trials. Despite technical improvements, expert clinical skills will continue to be one of the major determinants for the prognosis of patients with germ cell cancer. In addition, the particular needs of testicular cancer survivors have been acknowledged. (C) 2007 European Association of Urology. Published by Elsevier B.V. All rights reserved.

Results: The second part of the consensus paper includes the treatment of metastasised disease, residual tumour resection, salvage therapy, follow-up, and late toxicities. Conclusions: Whereas the vast majority of the recommendations made in 2004 remain valid 3 yr later, refinements in the treatment of early-stage as well as of advanced-stage testicular cancer have emerged from clinical trials.

  • Organizational Psychology: When, Why, and How Is Identity Work (Less) Important in Organizational Life?
  • 2021. - 2
  • Ingår i: The Cambridge Handbook of Identity. - : Cambridge University Press. - 9781108755146 ; , s. 586-603
  • Bokkapitel (refereegranskat)abstract
    • This chapter examines if identity is as important as is often claimed, and as a consequence, when and why concerns of identity are triggered in working life, and we do so through a constructionist identity perspective. In the chapter, we argue that many people do not necessarily engage with their identities most of the time and explore why they do in certain kinds of jobs and in particular situations while in others identity is neither present nor salient, at least not as a major issue. The chapter aims to cut down the identity concept in size and suggests that a more focused view on identity may help us come to better grips with what on one level is of great societal concern: identity-related struggle, tension, and confusion in people’s working lives; without adding too much to another concern: a (re)production of unwanted narcissism in our already narcissistic time of age.
