The cost of lying

We experimentally investigate the effect of cheap talk in a bargaining game with one-sided asymmetric information. A seller has private information about his or her skill and is provided an opportunity to communicate this information to a buyer through a written message. Four different treatments are compared; one without communication, one with free-form communication, and two treatments with pre-specified communication in the form of promises of varying strength. Our results suggest that lying about private information is costly and that the cost of lying increases with the size of the lie and the strength of the promise. Freely formulated messages lead to the fewest lies and the most efficient outcomes.Deception; Communication; Lies; Promises; Experiments

Förändring och kontinuitet

In the past eighty years, the Swedish university and higher education sector has undergone major changes. The conditions for conducting higher education and research have fundamentally changed. Universities and colleges have evolved from narrow elite institutions to educating large sections of the population and have increasingly attracted the interest of politics. They are located throughout the country and have gradually been assigned greater and greater resources and responsibilities. The majority of publicly funded research is currently conducted at the country's universities. At the same time, the sector's development has been characterized by considerable continuity. It is impossible to understand the structure of today's Swedish higher education landscape without taking into account the background and historical development of the universities and colleges. This report deals with developments in the period 1940–2020. The starting point is the state's reforms in higher education and research. It is both about broad, overarching reforms that affected large parts of the activities at universities and colleges in one context and about the continuous adaptation of regulations and systems. The purpose is to draw an overview of the development of the modern Swedish university. The report is primarily aimed at people working at universities and authorities, but also at politicians and people from the interested public who want to know more about the background to today's university and college system and why it looks the way it does. The report has been prepared by the University Chancellor's Office, as part of the mission to follow developments in Swedish higher education and research. The University Chancellor's Office also annually publishes up-to-date statistics on the Swedish university and a large number of reports on various themes

Nebulization of the acidified sodium nitrite formulation attenuates acute hypoxic pulmonary vasoconstriction

<p>Abstract</p> <p>Background</p> <p>Generalized hypoxic pulmonary vasoconstriction (HPV) occurring during exposure to hypoxia is a detrimental process resulting in an increase in lung vascular resistance. Nebulization of sodium nitrite has been shown to inhibit HPV. The aim of this project was to investigate and compare the effects of nebulization of nitrite and different formulations of acidified sodium nitrite on acute HPV.</p> <p>Methods</p> <p><it>Ex vivo </it>isolated rabbit lungs perfused with erythrocytes in Krebs-Henseleit buffer (adjusted to 10% hematocrit) and <it>in vivo </it>anesthetized catheterized rabbits were challenged with periods of hypoxic ventilation alternating with periods of normoxic ventilation. After baseline hypoxic challenges, vehicle, sodium nitrite or acidified sodium nitrite was delivered via nebulization. In the <it>ex vivo </it>model, pulmonary arterial pressure and nitric oxide concentrations in exhaled gas were monitored. Nitrite and nitrite/nitrate were measured in samples of perfusion buffer. Pulmonary arterial pressure, systemic arterial pressure, cardiac output and blood gases were monitored in the <it>in vivo </it>model.</p> <p>Results</p> <p>In the <it>ex vivo </it>model, nitrite nebulization attenuated HPV and increased nitric oxide concentrations in exhaled gas and nitrite concentrations in the perfusate. The acidified forms of sodium nitrite induced higher levels of nitric oxide in exhaled gas and had longer vasodilating effects compared to nitrite alone. All nitrite formulations increased concentrations of circulating nitrite to the same degree. In the <it>in vivo </it>model, inhaled nitrite inhibited HPV, while pulmonary arterial pressure, cardiac output and blood gases were not affected. All nitrite formulations had similar potency to inhibit HPV. The tested concentration of appeared tolerable.</p> <p>Conclusion</p> <p>Nitrite alone and in acidified forms effectively and similarly attenuates HPV. However, acidified nitrite formulations induce a more pronounced increase in nitric oxide exhalation.</p

JA 37:Pilot och system : transkript av ett vittnesseminarium vid Tekniska museet i Stockholm den 11 december 2007

The witness seminar ”JA 37 – Pilot och system” was held at the National Museum of Science and Technology in Stockholm on 11 December 2007 and was led by professor Karl Johan Åström. Different aspects of the use of Information Technology in the development of real time control systems in the fighter version of Viggen (JA 37) were discussed and debated, with special emphasis on integration of the systems surrounding the pilot. The critical importance of close cooperation between development engineers and test pilots, primarily at the customer FMV and the main contractor Saab, at LM Ericsson and Svenska Radiobolaget, and test pilots at Saab and the Swedish Air Force was underlined. This also included the emerging use of mission and task analysis, system simulators and early flying experimentation and test beds. The basic arcitechture of the airborne system with a central computer to which most of the major sub-systems and equipment was connected was carried over from the Attack Viggen System (AJ 37) with its single digital computer. The total system functionality and capability was vastly improved due to the introduction of digital computers in all major subsystems, an inertial platform, built-in test and data recording systems for maintenance, mission performance feedback and training purposes. A major undertaking was the development of an integrated Electronic Display System with three major displays: a Head-up Display (SI), a Tactical Situation Display (TI), including an all electronically generated map function, and a Radar/ Target Display (MI). In particular the development of the Tactical Indicator (TI), made possible by new solid state technology, facilitated more autonomous fighter tactics than possible with previous radar based command and control system. The all important challenge for the JA 37 project was the development of the pulse dopper radar PS-46/A, a task carried out by LM Ericsson with support from Hughes Aircraft Company and guidance from FMV. Special attention was paid to the use of digital computers for highspeed signals processing. Moreover, the critical design choice of medium pulse repetition frequency was debated. Finally, software development tools and methodology were discussed

LEO: Databehandling och operativ ledning inom försvaret, 1972-89 : Transkript av ett vittnesseminarium vid Högkvarteret i Stockholm den 15 januari 2008

The witness seminar ”LEO: Computing and Operational Command in the Swedish Armed Forces, 1972–89” was held at the Armed Forces Headquarter in Stockholm on 15 January 2008 and was led by Göran Tode. During the seminar, the development of the computerized command system LEO was discussed. After a major reorganisation of command structure in the late 1960s, the defence staff decided to develop a computerized command system to help central and regional headquarters conduct wartime operations. Each headquarter was to have one terminal system, with a number of work stations, containing information about all aspects of the battlefield. Information about friendly and enemy forces, fuel and ammunition supplies was to be stored in a central data base and a secure messaging system was to provide fast and reliable communications. Additional applications were developed to handle computations and simulations of transports and mobilization. Different aspects of this development were discussed at the seminar. Limitations in computer graphics and presentation technology was observed as a major technological problem in the early phase of the project. Other problems brought up concerned the considerable passive resistence from users and senior commanders, when new computer technology was introduced in old organizational structures. In addition to this, security started to emerge as a critical problem in the early 1980s when highly classified information about war plans, communications and intelligence were concentrated into a single computer system. Measures to control access of information in the system and to guarantee electronic security were discussed and debated. Moreover, the decision in 1979 to purchase mainframe computers from Norsk Data was covered at the seminar. The development of tools and methodology for COBOL programming was mentioned. Finally, the implementation of the system in central and regional staff headquarters in the late 1980s was also discussed.QC 20130422</p

Fri upplevelsekultur eller kulturfri upplevelse? : en bourdieusk analys av kulturdebatten som intellektuellt fält

Den här uppsatsen utgår ifrån Pierre Bourdieus teorier om intellektuella fält för att se på kulturdebatten i de stora dagstidningarna som medskapare av kulturens värde. Analysen bygger på en jämförelse med en undersökning som Donald Broady &amp; Mikael Palme gjorde i början av åttiotalet där de betraktar litteraturkritiken i huvudstadstidningarna som ett intellektuellt fält. De kommer där fram till att litteratur ges värde genom referenser till annan litteratur och att värdet även skapas genom vilka kritiker som uttalar sig i olika frågor. På samma vis ser den här uppsatsen på hur kulturen ges värde i kulturdebatten. Analysen är begränsad till att se på kulturdebatten kring Nya Slussen och den efterföljande vänster-högerdebatten kring kulturen. De nyliberala idéströmningar som finns i den nya kulturpolitiken återspeglas även i debatten och framstår tydligt genom vissa publiceringar, främst genom Bengt Ohlssons artikel i Dagens Nyheter den 4 januari 2012 med titeln Måste kulturen vara vänster. Denna artikel startade den debatt som kom att kallas vänstertvångdebatten och det är publiceringen av artikeln och de repliker Ohlsson fick som är uppsatsens huvudsakliga fokus. Debatten tycks efterhand handla om olika skribenters rätt att uttala sig samtidigt som skribenter med större kulturellt och symboliskt kapital agerar för att behålla fältets struktur. Det är dessa aspekter som uppsatsen ser på med Pierre Bourdieus terminologi
