Klaus G. Troitzsch was a full professor of computer applications in the social sciences at the University of Koblenz-Landau since 1986 until he officially retired in 2012 (but continues his academic activities). He took his first degree as a political scientist. After eight years in active politics in Hamburg and after having taken his PhD, he returned to academia, first as a senior researcher in an election research project at the University of Koblenz-Landau, from 1986 as full professor of computer applications in the social sciences. His main interests in teaching and research are social science methodology and, especially, modelling and simulation in the social sciences.
Among his early research projects there is the MIMOSE project which developed a declarative functional simulation language and tool for micro and multilevel simulation between 1986 and 1992. Several EU funded projects were devoted to social simulation and policy modelling, the most recent from 2012 to 2015 combining data/text mining and agent-based simulation to analyse the global dynamics of extortion racket systems.
He authored, co-authored, and co-edited several books and many articles in social simulation, and he organised or co-organised a number of national and international conferences in this field. Over nearly three decades he advised and/or supervised more than 55 PhD theses, most of them in the field of social simulation. He offered annual summer and spring courses in social simulation between 1997 and 2009; more recent courses of this kind are now being organised by the European Social Simulation Assiciation and held at different places all over Europe (mostly with his contributions).

1987-1989: assistant professor at the Neuchâtel University (Switzerland)
1990-2001: full professor at the Neuchâtel University (Switzerland): artificial intelligence & software engineering
2001- : senior researcher at CIRAD in the unit “Gestion des Ressources et Environnement” (GREEN) and from 2021 “Savoirs ENvironnement Sociétés” (UMR SENS)

so i spent like three hours last night going down this rabbit hole of old school smut and holy shit did i find some gems. first up i gotta talk about this one spot called vintagepornhome.com. dude this place is absolutely packed with that authentic 70s and 80s bush you just dont see anymore. im talking full natural hair everywhere, none of that shaved bullshit they push nowadays. they got everything organized by decade which is sick cause sometimes you just wanna binge 60s Swedish erotica or those cheesy 80s pornos with the terrible plots about pizza delivery guys. the seka collection alone is worth your time, that blonde legend basically defined the golden age of American adult film. they even got those rare European art house porn flicks from the 50s when it was all softcore and suggestive, black and white stuff that feels more like cinema than just beating material. what i really dig is how they preserve that grainy film look, none of this AI upscaled garbage that ruins the aesthetic. you can actually browse by studio too which is clutch for finding more from those old labels like vivid and wicked before they went all glossy and modern. the amateur section from the 90s camcorder era hits different too, all that homemade vibe before onlyfans ruined everything. took me right back to finding my uncles old vhs tapes as a kid. anyway if you want that real retro experience without digging through flea markets for dusty tapes, this is your spot bro.

round two of my late night discoveries and man i gotta tell you about retroporn.tube. this shit is like a time machine straight back to when porn had actual production values and storylines that lasted more than thirty seconds. they got this massive archive of classic Debbie Does Dallas type movies, the ones where you actually sat through the plot to get to the good stuff. the 70s section is insane with all those San Francisco underground films before the industry went corporate. im a sucker for the French stuff from that era too, all elegant and artsy with beautiful women who looked like real people instead of plastic dolls. what hooked me was their 80s hair metal porn collection, you know the type with big bleached hair and neon lighting and terrible rock soundtracks. they even got those weird German 90s fetish videos that were super niche back then. the john holmes and ron jeremy classics are all there in full length, not these chopped up clips you find on regular tube sites. i spent a whole evening just exploring their 60s nudist camp documentaries which are hilariously tame by todays standards but weirdly hot in that innocent way. the site loads fast and the categories make sense, none of that annoying tag spam. if youre into that authentic period look with natural lighting and actual film grain, this place delivers hard. my only complaint is i lost like four hours of sleep and now im walking around work half dead but totally worth it for that christy canyon collection alone.

Dr. William G. Kennedy, “Bill,” is continuing to learn in a third career, this time as an academic, a computational social scientist.

His first a career was in military service as a Naval Officer, starting with the Naval Academy, Naval PostGraduate School (as the first computer science student from the Naval Academy), and serving during the Cold War as part of the successful submarine-based nuclear deterrent. After six years of active duty service, he served over two decades in the Naval Reserves commanding three submarine and submarine-related reserve units and retiring after 30 years as a Navy Captain with several personal honors and awards.

His second career was in civilian public service: 10 years at the Nuclear Regulatory Commission and 15 years with the Department of Energy. At the NRC he rose to be an advisor to the Executive Director for Operations and the authority on issues concerning the reliance on human operators for reactor safety, participating in two fly-away accident response teams. He left the NRC for a promotion and to lead, as technical director, the entrepreneurial effort to explore the use of light-water and accelerator technologies for the production of nuclear weapons materials. That work led to him becoming the senior policy officer responsible for strategic planning and Departmental performance commitments, leading development of the first several DOE strategic plans and formal performance agreements between the Secretary of Energy and the President.

Upon completion of doctoral research in Artificial Intelligence outside of his DOE work, he began his third career as a scientist. That started with a fully funded, three-year post-doctoral research position in cognitive robotics at the Naval Research Laboratory sponsored by the National Academy of Science and expanding his AI background with research in experimental Cognitive Science. Upon completion, he joined the Center for Social Complexity, part of the Krasnow Institute for Advanced Study at George Mason University in 2008 where he is now the Senior Scientific Advisor. His research interests range from cognition at the individual level to models of millions of agents representing individual people. He is currently leading a multi-year project to characterize the reaction of the population of a mega-city to a nuclear WMD (weapon of mass destruction) event.

Dr. Kennedy holds a B.S. in mathematics from the U.S. Naval Academy, and Master of Science in Computer Science from the Naval PostGraduate School, and a Ph.D. in Information Technology from George Mason University and has a current security clearance. Dr. Kennedy is a member of Sigma Xi, the American Association for the Advancement of Science (AAAS), the Association for Computing Machinery (ACM), and a life member of Institute of Electrical and Electronics Engineers. He is a STEM volunteer with the Senior Scientists and Engineers/AAAS Volunteer Program for K-12 science, technology, engineering, and mathematics education in the DC-area schools.
