A quasi-materialist, quasi-dualist solution to the mind-body problem

If the mental can affect, or be affected by, the physical, then the mental must itself be physical. Otherwise the physical world would not be explanatorily closed. But it is closed. There are reasons to hold that materialism (in both its reductive and non-reductive varieties) is false. So how are we to explain the apparent responsiveness of the physical to the mental and vice versa? The only possible solution seems to be this: physical objects are really projections or isomorphs of objects whose essential properties are mental. (A slightly less accurate way of putting this would be to say: the constitutive - i.e. the non-structural and non-phenomenal - properties of physical objects are mental, i.e. are such as we are used to encountering only in "introspection".) The chair, qua thing that I can know through sense perception, and through hypotheses based strictly thereupon, is a kind of shadow of an object that is exactly like it, except that this other objects essential properties are mental. This line of thought, though radically counterintuitive, explains the apparent responsiveness of the mental to the physical, and vice versa, without being open to any of the criticisms to which materialism, dualistic interaction ism, and epiphenomenalism are open.

Våld i parrelationer : en begreppslig undersökning av ett moraliskt och samhälleligt problem

Mäns våld mot kvinnor i parrelationer är ett förekommande problem i det finländska samhället. Som en moralisk fråga råder det ingen tvekan om att våld i parrelationer är orätt. Den moraliska diskussionen kan ändå inte stanna där. När våldsproblematiken studeras närmare träder flera aspekter av moralfilosofiskt intresse fram. Detta är dock sammanlänkat med hela avhandlingens utgångspunkt: att moralfrågor i första hand är frågor i första person. Det handlar om hur var och en av oss som de personer vi är förhåller oss till andra människor i olika situationer. Det handlar om hur varje enskild person berörs av, möter eller står tyst inför t.ex. en problematik som våld i parrelationer. Genom den här utgångspunkten problematiserar avhandlingen en vanlig syn på etik och moral som en uppsättning yttre regler eller som något vi helt objektivt kan resonera kring utan att själva egentligen beröras och bli indragna i det vi diskuterar, eller utan hänsyn till dem som faktiskt berörs. Tyngdpunkten i avhandlingen läggs på en moralisk begreppslig undersökning kring ett antal begrepp som stiger fram som relevanta i mötet med våld i parrelationer. De för avhandlingen centrala begreppen är offentligt-privat, rättvisa, rättigheter, makt, skam, skuld, förlåtelse, omsorg, tillit och ansvar. I avhandlingen har jag beskrivit, kritiskt analyserat samt fördjupat en förståelse av dessa begrepp och uttryck som både rör ett individ- och ett samhällsplan. Hur dessa begrepp och uttryck används och fungerar i olika sammanhang uttrycker moraliska förhållningssätt gentemot våld, offer och förövare. I avhandlingen synliggörs detta och en konkret förankring sker med hjälp av följande material: finländskt lagstiftningsmaterial (förarbeten till lagar som berör våld i parrelationer under perioden 1991-2006) och berättelser av kvinnor som upplevt våld. Den begreppsliga analysen, där bl.a. olika feministiska teoretiker används, visar att språket inte är neutralt. Språket kan vara färgat av flera självklara förutsättningar och distanserande begrepp kan användas på ett sådant sätt att det moraliskt mest centrala och brännande döljs.

Rädsla inför förlossningen - ett uppenbart kliniskt problem? : konstruktionen av förlossningsrädsla som medicinsk kategori

Kvinnors känsla av oro och rädsla inför förlossningen har under de senaste årtiondena intresserat forskare inom en medicinsk kontext, framför allt i Sverige och Finland. Den obstetriska och psykologiska forskningen har strävat efter att definiera, finna metoder för att mäta samt klassificera dessa känslor. Begreppet förlossningsrädsla används i dag ofta såväl inom den medicinska diskursen som bland allmänheten som ett samlande begrepp för att beskriva föderskors rädsla både inför, under och efter förlossningen. Trots detta finns det ändå ingen allmänt vedertagen definition av eller enhetliga kriterier för vad som skall inkluderas i begreppet. Förlossningsrädsla har konstruerats och etablerats som ett till synes objektivt medicinskt definierat fenomen och vården av förlossningsrädsla har institutionaliserats inom specialsjukvården. Däremot har de praktiker och institutioner som bidragit till att skapa förlossningsrädsla som ett vetenskapligt faktum, en svart låda, blivit osynliga. I "Rädsla inför förlossningen – ett uppenbart kliniskt problem? Konstruktionen av förlossningsrädsla som en medicinsk kategori" granskas uppkomsten, etableringen och institutionaliseringen av förlossningsrädsla som en medicinsk kategori inom vetenskaplig forskningslitteratur i Sverige och Finland. I fokus för analysen står processer av kunskapsproduktion genom vilka förlossningsrädsla formuleras som en specifik medicinsk kategori. Förlossningsrädsla som begrepp och kategori kan beskrivas som ett gränsöverskridande objekt som ständigt reproduceras och konsolideras genom den pågående forskningen.

Active teaching-learning methodologies: medical students' views of problem-based learning

The prevailing undergraduate medical training process still favors disconnection and professional distancing from social needs. The Brazilian Ministries of Education and Health, through the National Curriculum Guidelines, the Incentives Program for Changes in the Medical Curriculum (PROMED), and the National Program for Reorientation of Professional Training in Health (PRO-SAÚDE), promoted the stimulus for an effective connection between medical institutions and the Unified National Health System (SUS). In accordance to the new paradigm for medical training, the Centro Universitário Serra dos Órgãos (UNIFESO) established a teaching plan in 2005 using active methodologies, specifically problem-based learning (PBL). Research was conducted through semi-structured interviews with third-year undergraduate students at the UNIFESO Medical School. The results were categorized as proposed by Bardin's thematic analysis, with the purpose of verifying the students' impressions of the new curriculum. Active methodologies proved to be well-accepted by students, who defined them as exciting and inclusive of theory and practice in medical education.

General terms and rigidity: another solution to the trivialization problem

In this paper I am concerned with the problem of applying the notion of rigidity to general terms. In Naming and Necessity, Kripke has clearly suggested that we should include some general terms among the rigid ones, namely, those common nouns semantically correlated with natural substances, species and phenomena, in general, natural kinds -'water', 'tiger', 'heat'- and some adjectives -'red', 'hot', 'loud'. However, the notion of rigidity has been defined for singular terms; after all, the notion that Kripke has provided us with is the notion of a rigid designator. But general terms do not designate single individuals: rather, they apply to many of them. In sum, the original concept of rigidity cannot be straightforwardly applied to general terms: it has to be somehow redefined in order to make it cover them. As is known, two main positions have been put forward to accomplish that task: the identity of designation conception, according to which a rigid general term is one that designates the same property or kind in all possible worlds, and the essentialist conception, which conceives of a rigid general term as an essentialist one, namely, a term that expresses an essential property of an object. My purpose in the present paper is to defend a particular version of the identity of designation conception: on the proposed approach, a rigid general term will be one that expresses the same property in all possible worlds and names the property it expresses. In my opinion, the position can be established on the basis of an inference to the best explanation of our intuitive interpretation and evaluation, relative to counterfactual circumstances, of statements containing different kinds of general terms, which is strictly analogous to our intuitive interpretation and evaluation, relative to such circumstances, of statements containing different kinds of singular ones. I will argue that it is possible to offer a new solution to the trivialization problem that is thought to threaten all versions of the identity of designation conception of rigidity. Finally, I will also sketch a solution to the so-called 'over-generalization and under-generalization problems', both closely related to the above-mentioned one.

The knapsack problem approach in solving partial hedging problems of options

En option är ett finansiellt kontrakt som ger dess innehavare en rättighet (men medför ingen skyldighet) att sälja eller köpa någonting (till exempel en aktie) till eller från säljaren av optionen till ett visst pris vid en bestämd tidpunkt i framtiden. Den som säljer optionen binder sig till att gå med på denna framtida transaktion ifall optionsinnehavaren längre fram bestämmer sig för att inlösa optionen. Säljaren av optionen åtar sig alltså en risk av att den framtida transaktion som optionsinnehavaren kan tvinga honom att göra visar sig vara ofördelaktig för honom. Frågan om hur säljaren kan skydda sig mot denna risk leder till intressanta optimeringsproblem, där målet är att hitta en optimal skyddsstrategi under vissa givna villkor. Sådana optimeringsproblem har studerats mycket inom finansiell matematik. Avhandlingen "The knapsack problem approach in solving partial hedging problems of options" inför en ytterligare synpunkt till denna diskussion: I en relativt enkel (ändlig och komplett) marknadsmodell kan nämligen vissa partiella skyddsproblem beskrivas som så kallade kappsäcksproblem. De sistnämnda är välkända inom en gren av matematik som heter operationsanalys. I avhandlingen visas hur skyddsproblem som tidigare lösts på andra sätt kan alternativt lösas med hjälp av metoder som utvecklats för kappsäcksproblem. Förfarandet tillämpas även på helt nya skyddsproblem i samband med så kallade amerikanska optioner.

Chelyabinsk CHP-3 “locked power” problem solving

All over the world power systems become bigger and bigger every day. New equipment is installed, new feeders are constructed, new power units are installed. Some old elements of the network, however, are not changed in time. As a result, “bottlenecks” for capacity transmission can occur. By locked power problem the situation when a power plant has installed capacity exceeding the power it can actually deliver is usually meant. Regime, scheme or even technical restrictions-related issues usually cause this kind of problem. It is really important, since from the regime point of view it is typical decision to have a mobile capacity reserve, in case of malfunctions. And, what can be even more significant, power plant owner (JSC Fortum in our case) losses his money because of selling less electrical energy. The goal of master`s thesis is to analyze the current state of Chelyabinsk power system and the CHP-3 (Combined Heat and Power plant) in particular in relation with it`s ability to deliver the whole capacity of the CHP in it`s existing state and also taking into consideration the prospect of power unit 3 installation by the fourth quarter of 2010. The thesis contains some general information about the UPS of Russia, CPS of Ural, power system of Chelyabinsk and the Chelyabinsk region itself. Then the CHP-3 is described from technical point of view with it`s equipment observation. Regimes for the nowadays power system and for the system after the power unit 3 installation are reviewed. The problems occurring are described and, finally, a solution is offered.

Contact with friction using the augmented Lagrangian Method: a conditional constrained minimization problem

This work presents a formulation of the contact with friction between elastic bodies. This is a non linear problem due to unilateral constraints (inter-penetration of bodies) and friction. The solution of this problem can be found using optimization concepts, modelling the problem as a constrained minimization problem. The Finite Element Method is used to construct approximation spaces. The minimization problem has the total potential energy of the elastic bodies as the objective function, the non-inter-penetration conditions are represented by inequality constraints, and equality constraints are used to deal with the friction. Due to the presence of two friction conditions (stick and slip), specific equality constraints are present or not according to the current condition. Since the Coulomb friction condition depends on the normal and tangential contact stresses related to the constraints of the problem, it is devised a conditional dependent constrained minimization problem. An Augmented Lagrangian Method for constrained minimization is employed to solve this problem. This method, when applied to a contact problem, presents Lagrange Multipliers which have the physical meaning of contact forces. This fact allows to check the friction condition at each iteration. These concepts make possible to devise a computational scheme which lead to good numerical results.

Inverse convection problem of simultaneous estimation of two boundary heat fluxes in parallel plate channels

This paper deals with the use of the conjugate gradient method of function estimation for the simultaneous identification of two unknown boundary heat fluxes in parallel plate channels. The fluid flow is assumed to be laminar and hydrodynamically developed. Temperature measurements taken inside the channel are used in the inverse analysis. The accuracy of the present solution approach is examined by using simulated measurements containing random errors, for strict cases involving functional forms with discontinuities and sharp-corners for the unknown functions. Three different types of inverse problems are addressed in the paper, involving the estimation of: (i) Spatially dependent heat fluxes; (ii) Time-dependent heat fluxes; and (iii) Time and spatially dependent heat fluxes.

Analysis of Regular and Irregular Dynamics of a Non Ideal Gear Rattling Problem

This paper presents a study on the dynamics of the rattling problem in gearboxes under non-ideal excitation. The subject has being analyzed by a number of authors such as Karagiannis and Pfeiffer (1991), for the ideal excitation case. An interesting model of the same problem by Moon (1992) has been recently used by Souza and Caldas (1999) to detect chaotic behavior. We consider two spur gears with different diameters and gaps between the teeth. Suppose the motion of one gear to be given while the motion of the other is governed by its dynamics. In the ideal case, the driving wheel is supposed to undergo a sinusoidal motion with given constant amplitude and frequency. In this paper, we consider the motion to be a function of the system response and a limited energy source is adopted. Thus an extra degree of freedom is introduced in the problem. The equations of motion are obtained via a Lagrangian approach with some assumed characteristic torque curves. Next, extensive numerical integration is used to detect some interesting geometrical aspects of regular and irregular motions of the system response.
