Proportional representation and development : some critical thoughts

The issue of a majority electoral system versus proportional representation has been debated for years. It rears its head after every British election, and it is increasingly discussed in Malta. But the effects of electoral systems on local government have all but been ignored, as have the respective merits of the systems in underdeveloped areas.peer-reviewe

Le baptême adulte de chrétiens tunisiens : rituel public d’un engagement privé

International audienceLe développement du protestantisme évangélique au Maghreb est attesté depuis une vingtaine d’années et des travaux en sciences sociales commencent à en dessiner les particularités. Dans cet article, l’auteur pose la question de la place du baptême en tant que rite de passage dans la communauté chrétienne en Tunisie. En choisissant d’analyser cet évènement, ce moment, il s’agit de comprendre comment s’y articulent différents éléments tels que la revendication de la légitimité de la religion chrétienne au Maghreb par l’évocation de l’histoire antique de la région et l’entrée dans une famille religieuse contemporaine, universelle, distincte de celle dans laquelle le croyant est né. La question du moment « opportun » du baptême est également abordée, dans la mesure où elle se pose pour les intéressés, qu’il s’agisse des convertis eux-mêmes ou des cadres religieux, représentants de l’institution

Danae Boissevain

Selected excerpts from the Oral History Project interview. The full transcript may be restricted. To request access contact the Simon’s Rock College Archives. The English department came to me when I first arrived, very slowly, one after the other. Because of my name! They would say, “This surname, your last name, is interesting. Are you related?” They wanted to know if I was related to Edna St. Vincent Millay, the poet who lived in Austerlitz. Her husband was Eugene Boissevain, and all the Boissevains are related. Of course, that was my husband’s name. So that’s how I met a lot of the English faculty. But each one came in: Bernie [Rodgers], Peter [Filkins]. They all came in, one after the other. “It is a strange name. Is it possible that you’re connected?” So that was nice, because it’s hard to meet them otherwise. Bob Ackerman and I got computers more or less at the same time. You have to realize, there was a “before computer” era at Simon’s Rock and “after.” To begin with, there was one. And it was in the admissions office. One computer, and we had to queue up to use it. You had to put down your name when you thought you could use it, so I put one evening. And I was adamant that I didn’t need a computer. I was much faster on a typewriter and I didn’t want to learn. So my boss, Chris Milloff said, “You have to learn!” she said, “We’ll do it on Saturdays.” So she would call in and I would sit at my desk and she would put me through some exercises and then leave. I can remember printing something and I couldn’t stop it. It was one of those things-- it printed until it ran out of paper. It was awful. I just could not see the point of this. But Ackerman, Bob Ackerman, came down-- I was now on the ground floor, and he came round because he had just learned how to delete something. It was so exciting, we all had to share our knowledge! Once I was hired, I got to know the local newspapers. I invited a meeting with the AP writer, the educational AP writer: how am I going to get people to hear about Simon’s Rock? He was wonderful. He said, “You’ve got to figure out how you’re going to interest an older lady in Wichita in what is happening here. You have to figure it out. You just told me Simon’s Rock is so many years old-- that’s not news. You have to find a way to interest that lady.” So I did. And it was the first story I got on a national level. We did an interview, and the headline was “Skipping High School, Goes to College.” And that was the headline that I tried to use forever after, because that made sense. A young person choosing to skip high school. And it went national. The coverage for that story was mega. It was wonderful. We were all told-- all of the staff-- that we were allowed to take classes, and it occurred to me that I would love to take one of Larry’s classes, having worked with him for so long. So I did. I think I signed up for 20th Century Composers. [...] The interesting thing was, he knew what I would know in the class. So he asks students questions, and somehow or another he knew what I would know and what they didn’t know. And I did know! And it was very exciting because I thought I was a neophyte. Our homework was always to listen. I was late one day, hadn’t listened, ran into the library, to the listening room, and there was the entire class doing the same thing! It was wonderful. Every graduation I would say [to Leon], “Could you give me the speech?” because I’d like to give it to a reporter. It’s very helpful to have the words; they can get on with their job quicker. And I’d always ask, just before graduation, before they march: “Could I have your speech?” And he’d say, “Oh, Danae, I don’t have it written!” And he never did. It was always perfect, whatever he came up with. He’d somehow tie together what other people had said, or he went off on another tack. Whatever it was, it was just perfect. So we had to try to write it down. He was admirable, this man. I really enjoyed him so much. At the time of the shooting, Diane Rhoades[-Warner], who was on the switchboard, called me at midnight, and said, “Danae, what shall I tell CNN?” She was always on the switchboard, she knew that I would always like to hear from any kind of press person. And so she said, “What shall I tell CNN?” And I said, “What was the question?” And she said, “There’s been a shooting.” And I said, “What’s happened? Can you tell me the details?” And she burst into tears. She was not in good shape. I said, “Hold on, I’ll be right over and we’ll figure out what we have to do.” I wrote a note on a big yellow legal pad for my daughter, who was asleep, saying, “I’m at Simon’s Rock, I’ll be back.” And then I drove over to Simon’s Rock. I thought, “Am I being sensible about this, if there’s been a shooting and I’m driving around like this?” So I sort of snuck down in the car, like this [slumps down on her couch] so I wouldn’t be as visible. [...] Ñacuñán had this scarf-- he would walk around campus with this scarf around his neck, it was a great panache about him. He was just funny! And fun. And he would always send me postcards of Danaes, whenever he went to Europe, he would go to a museum and whenever he saw a portrait of a Danae, he would send it to me. I loved doing the alumni magazines because you could develop a theory or a theme for each issue and you would call all these incredible people and they would say all these amazing things about what they were doing and how much Simon’s Rock had altered their careers, their lives. It was always amazing stories. It was a really fabulous job. I used to go to lunch at the dining hall. That was my epicenter, because I knew everyone had to go there at some point, and if I waited long enough, I could get anyone I needed. I really enjoyed going there because it was important for my work. But also, I don’t know if this is still true, but we all-- lunch was free for everyone. [...] It was fantastic, it was the best part of the day. When I retired, Mary Marcy gave me a little tea [party] and I said thank you to the people I had enjoyed working with, and they did a very nice presentation, and I said what I was going to miss most-- what I’d really miss was lunch. And so Mary Marcy got up and said, “Well, we’ve got you a chair but I think what we really should do is, obviously, you would prefer lunch! So I’m arranging for you to have a lifetime’s worth of lunch in the dining hall!”https://digitalcommons.bard.edu/sr-oral_hist/1004/thumbnail.jp

Aerodynamic characteristics of a large-scale hybrid upper surface blown flap model having four engines

Data are presented from an investigation of the aerodynamic characteristics of large-scale wind tunnel aircraft model that utilized a hybrid-upper surface blown flap to augment lift. The hybrid concept of this investigation used a portion of the turbofan exhaust air for blowing over the trailing edge flap to provide boundary layer control. The model, tested in the Ames 40- by 80-foot Wind Tunnel, had a 27.5 deg swept wing of aspect ratio 8 and 4 turbofan engines mounted on the upper surface of the wing. The lift of the model was augmented by turbofan exhaust impingement on the wind upper-surface and flap system. Results were obtained for three flap deflections, for some variation of engine nozzle configuration and for jet thrust coefficients from 0 to 3.0. Six-component longitudinal and lateral data are presented with four engine operation and with the critical engine out. In addition, a limited number of cross-plots of the data are presented. All of the tests were made with a downwash rake installed instead of a horizontal tail. Some of these downwash data are also presented

Waste Heat Utilization in an Anaerobic Digestion System

Anaerobic digestion has great potential as an energy source. Not only does it provide an effective method for waste mitigation, but it has the potential to generate significant quantities of fuel and electricity. In order to ensure efficient digestion and biomass utilization, however, the system must be continuously maintained at elevated temperatures. It is technically feasible to supplement such a system with outside energy, but it is more cost effective to heat the system using only the produced biogas. While there is considerable literature covering the theory of anaerobic digestion, there are very few practical studies to show how heat utilization affects system operation. This study considers the effect of major design variables (i.e. heat exchanger efficiencies and biogas conditioning) on promoting a completely self-sustaining digestion system. The thesis considers a real world system and analyzes how it can be improved to avoid the need of an external energy source

Information Processing In Chronic Pain: The Role Of Depression

Over the last three decades, chronic pain has become conceptualized as a multidimensional phenomenon, in that cognitive and emotional factors have become acknowledged as important contributors to the experience and expression of chronic pain. Although this general theoretical understanding of chronic pain has become widely accepted, there has been relatively little research to date which attempts to delineate the specific ways in which cognitive operations may be influenced by various dimensions of chronic pain. The present dissertation represents an attempt to expand upon the empirical knowledge regarding cognitive processing in chronic pain. Specifically, the present project has been designed to examine the relative influence of chronic pain and depression on attention, short-term memory, and long-term memory. In general terms, it was expected that processing of pain and emotion-relevant stimuli would each be biased in a direction which was congruent with the pain or emotional status of the subjects.;Two pilot studies were run to determine the relevant parameters of phenomena under consideration. Pilot Study I was designed to investigate the relationship of depressed mood to sensory and affective dimensions of chronic pain. Using psychometric methodology, it was found that depressed mood was more strongly associated to the affective than to the sensory dimension of chronic pain. Pilot Study II was designed as a preliminary examination of the selective effect of chronic pain and depressed mood on state-specific attentional processes, as exemplified by a modified Stroop task. That Pilot Study II did not yield the predicted results was explained in terms of diagnostic criteria and potential uncontrolled methodologically-related variance. Results obtained in Pilot Study I informed much of the design and methodology employed in the principal study.;Subjects in the principal study were selected on the basis of rigorous diagnostic criteria to form the following four groups: pain-depressed, pain-nondepressed, nonpain-depressed, and nonpain-nondepressed. The principal study was comprised of three components. Phase I was a modified Stroop task, which used methodology modified on the basis of results obtained in Pilot Study II. Phase II was an autobiographical memory task, and Phase III was an incidental recognition task. In general, it was found that chronic pain and depression each exerted a unique biasing influence on each of the cognitive processes investigated in the three phases of the principal study. Results of the present project were discussed in terms of their theoretical and clinical implications
