    A quasi classical approach to electron impact ionization

    Get PDF
    A quasi classical approximation to quantum mechanical scattering in the Moeller formalism is developed. While keeping the numerical advantage of a standard Classical--Trajectory--Monte--Carlo calculation, our approach is no longer restricted to use stationary initial distributions. This allows one to improve the results by using better suited initial phase space distributions than the microcanonical one and to gain insight into the collision mechanism by studying the influence of different initial distributions on the cross section. A comprehensive account of results for single, double and triple differential cross sections for atomic hydrogen will be given, in comparison with experiment and other theories.Comment: 21 pages, 10 figures, submitted to J Phys

    Joint ICOH-WOPS & APA-PFAW global roundtable perspectives : exploring national policy approaches for psychological health at work through the ‘National Policy Index’ lens

    Worker psychological health is a significant global imperative which requires national policy action and stakeholder engagement. While national policy is a critical lever for improving worker psychological health, some countries are more progressive than others in relation to policy development and/or implementation. At the Joint Congress of the International Commission on Occupational Health, Scientific Committee on Work Organization and Psychosocial Factors and the Asia Pacific Academy for Psychosocial Factors Work in Tokyo (September 2023), a Global Roundtable was designed to initiate international dialogue and knowledge exchange regarding relevant national policy approaches. The Global Roundtable involved experts from diverse regions alongside an engaged audience of congress attendees and facilitators. Qualitative data were analysed against the five components of the National Policy Index tool, comprising policy priority, specific laws, nation-wide initiatives, sector-oriented initiatives, national survey and/or studies. Analysis revealed that while work-related psychological health is a policy priority across many countries, at the same time, there are global gaps in both legislation specificity and active regulation across different countries. For future policy development across countries, it will be beneficial to continue and deepen international discourse and for countries to share their approaches with others

    Marketing as a means to transformative social conflict resolution: lessons from transitioning war economies and the Colombian coffee marketing system

    Get PDF
    Social conflicts are ubiquitous to the human condition and occur throughout markets, marketing processes, and marketing systems.When unchecked or unmitigated, social conflict can have devastating consequences for consumers, marketers, and societies, especially when conflict escalates to war. In this article, the authors offer a systemic analysis of the Colombian war economy, with its conflicted shadow and coping markets, to show how a growing network of fair-trade coffee actors has played a key role in transitioning the country’s war economy into a peace economy. They particularly draw attention to the sources of conflict in this market and highlight four transition mechanisms — i.e., empowerment, communication, community building and regulation — through which marketers can contribute to peacemaking and thus produce mutually beneficial outcomes for consumers and society. The article concludes with a discussion of implications for marketing theory, practice, and public policy

    A Tale of Two Visions: Can a New View of Personality Help Integrate Psychology?

    Get PDF
    Personality psychology studies how psychological systems work together. Consequently, the field can act as a unifying resource for the broader discipline of psychology. Yet personality’s current fieldwide organization promotes a fragmented view of the person, seen through such compet-ing theories as the psychodynamic, trait, and humanistic. There exists an alternative—a systems framework for per-sonality—that focuses on 4 topics: identifying personality, personality’s parts, its organization, and its development. This new framework and its view of personality are de-scribed. The framework is applied to such issues as per-sonality measurement, psychotherapy outcome research, and education. The new framework may better organize the field of personality and help with its mission of addressing how major psychological systems interrelate
