    Early Retransmit for TCP and SCTP2008Other (Other (popular science, discussion, etc.))
    Abstract [en]

    This document proposes a new mechanism for TCP and SCTP that can be used to recover lost segments when a connection's congestion window is small. The "Early Retransmit" mechanism allows the transport to reduce, in certain special circumstances, the number of duplicate acknowledgments required to trigger a fast retransmission. This allows the transport to use fast retransmit to recover packet losses that would otherwise require a lengthy retransmission timeout.

    Den utbredda flexibiliteten: Ett försök att beräkna förekomsten av lågreglerade arbetsvillkor2012In: Arbetsmarknad & Arbetsliv, ISSN 1400-9692, Vol. 18, no 1, p. 9-24Article in journal (Refereed)
    Abstract [sv]

    Nästan 30 år efter det att begreppet flexibilitet i arbetslivet kom i bruk råder det fortfarande stor osäkerhet om vad begreppet innebär och hur vanligt det egentligen är. I artikeln diskuteras flexibilitet utifrån en representativ studie av den svenska arbetskraften. I studien konstateras att både traditionellt organiserade och helt fria arbeten är relativt ovanliga. Däremot är flexibla arbetsvillkor desto mer vanligt förekommande och spridda i varierande grad bland den svenska arbetskraften.

    "Självständiga lärosäten": Om de förändrade villkoren för högre utbildning och universitetens normalisering2011In: Arbetsmarknad & Arbetsliv, ISSN 1400-9692, Vol. 17, no 2, p. 59-73Article in journal (Refereed)
    Abstract [sv]

    När den högre utbildningen avregleras får universitet  och högskolor själva bestämma hur de ska organisera sin verksamhet. Det sker även i den övriga västvärlden, liksom i den övriga svenska offentliga sektorn. Frågan är dock vad ett sådant självbestämmande egentligen är värt. Avregleringen lämnar nämligen lärosätena att konkurrera med varandra på en allt snävare och alltmer standardiserad spelplan, vilket i sin tur tvingar dem till långtgående rationaliseringar och prioriteringar.

    Abstract [en]

    Teaching materials and students with mental retardation



    From a socio-cultural perspective, teaching materials can be regarded as mediating tools for transferring culturally based knowledge, norms, values and traditions. While literature on teaching materials in general is substantial, few investigations have been conducted on teaching materials for students with mental retardation.



    In this paper I will present parts of an ongoing project in which this issue is focused. The study includes about twenty students in two training school classes and one class for students with mild mental retardation, covering the grades 7 10 in the compulsory school.



    Teaching materials in this study are defined as cultural tools used in education and serving a pedagogical function in programs for students with mental retardation (särskolan). My preliminary findings indicate predominance for everyday skills in teaching material activities. Reading or mathematical development in teaching material activities are of low priority. The activities often imply dilemmas the teacher have to master.

    Abstract [en]

    It has recently been argued that the Special Theory of Relativity entails that shapes are not intrinsic properties of objects. Rather, they are properties an object has only relative to an inertial frame. In this discussion note I argue that this position, while correct, is incomplete. Objects have frame-dependent shapes because they have an intrinsic property that is the same in all inertial frames.

    Affordances and the Nature of Perceptual Content2008In: International journal of philosophical studies (Print), ISSN 0967-2559, E-ISSN 1466-4542, Vol. 16, no 2, p. 161-177Article in journal (Refereed)
    Abstract [en]

    According to John McDowell, representational perceptual content is conceptual through and through. This paper criticizes this view by claiming that there is a certain kind of representational and non-conceptual perceptual content that is sensitive to bodily skills. After a brief introduction to McDowell's position, Merleau-Ponty's notion of body schema and Gibson's notion of affordance are presented. It is argued that affordances are constitutive of representational perceptual content, and that at least some affordances, the so-called 'conditional affordances', are essentially related to the body schema. This means that the perceptual content depends upon the nature of the body schema. Since the body schema does not pertain to the domain that our conceptual faculties operate upon, it is argued that this kind of perceptual content cannot be conceptual. At least some of that content is representational, yet it cannot feature as non-demonstrative conceptual content. It is argued that if it features as demonstrative conceptual content, it has to be captured by private concepts. Since McDowell's theory does not allow for the existence of a private language, it is concluded that at least some representational perceptual content is non-conceptual.

    An Argument for Shape Internalism2017In: Erkenntnis, ISSN 0165-0106, E-ISSN 1572-8420, Vol. 82, no 4, p. 819-836Article in journal (Refereed)
    Abstract [en]

    This paper is a defense of an internalist view of the perception of shapes. A basic assumption of the paper is that perceptual experiences have certain parts which account both for the phenomenal character associated with perceiving shapes-phenomenal shapes-and for the intentional content presenting shapes-intentional shapes. Internalism about perceptions of shapes is defined as the claim that phenomenal shapes determine the intentional shapes. Externalism is defined as the claim that perceptual experiences represent whatever shape the phenomenal shape reliably tracks. The argument against externalism proceeds in three steps. First, it is argued that phenomenal shapes are modality specific, such that a phenomenal shape that features in a visual perceptual experience cannot feature in a haptic perceptual experience, and vice versa. Second, it is argued that intentional shapes are amodal. Third, it is argued that externalism is incompatible with the fact that phenomenal shapes are modality specific and intentional shapes amodal.

    Perceiving Exploding Tropes2016In: Grazer Philosophische Studien, ISSN 0165-9227, E-ISSN 1875-6735, Vol. 93, no 1, p. 42-62Article in journal (Refereed)
    Abstract [en]

    The topic of this paper is the perception of properties. It is argued that the perception of properties allows for a distinction between the sense of the identity and the sense of the qualitative nature of a property. So, for example, we might perceive a property as being identical over time even though it is presented as more and more determinate. Thus, you might see an object first as red and then as crimson red. In this case, the property is perceived as identical over time, even though the sense of the qualitative nature ( the redness, the crimson redness) of the property is changing. The distinction between the sense of identity and the sense of quality is explicated in terms of perceiving a particular property, a trope, and perceiving it as an instance of a universal. It is subsequently argued that the perceived tropes cannot constitute the phenomenal character of the perceptual experience.

    Perceptual Transparency and Perceptual Constancy2014In: Husserl Studies, ISSN 0167-9848, E-ISSN 1572-8501, Vol. 30, no 1, p. 1-19Article in journal (Refereed)
    Abstract [en]

    A central topic in discussions about qualia concerns their purported transparency. According to transparency theorists, an experience is transparent in the sense that the subject having the experience is aware of nothing but the intended object of the experience. In this paper this notion is criticized for failing to account for the dynamical aspects of perception. A key assumption in the paper is that perceptual content has a certain temporal depth, in the sense that each act of perception can present an object as extended in time and that objects can be perceived as persisting through time. An object that is seen as persisting through time is often seen as constant and unchanging, even though the presentation of it is changing. In this paper it is argued that in order to account for these cases of perceptual constancy, we must distinguish between the awareness of having perceived that an object has a property at a certain point in time, and perceptually intending that it has that property at that point in time. Consequently, we must in at least some instances be aware of something more than the object of the experience. But precisely this distinction is rejected by the transparency theory.

    The Causal Self-Referential Theory of Perception Revisited2013In: Dialectica, ISSN 0012-2017, E-ISSN 1746-8361, Vol. 67, no 1, p. 29-53Article in journal (Refereed)
    Abstract [en]

    This is a paper about The Causal Self-Referential Theory of Perception. According to The Causal Self-Referential Theory as developed by above all John Searle and David Woodruff Smith, perceptual content is satisfied by an object only if the object in question has caused the perceptual experience. I argue initially that Searle's account cannot explain the distinction between hallucination and illusion since it requires that the state of affairs that is presented in the perceptual experience must exist in order for the perception to be veridical. Smith's account is interestingly different in that the descriptive content, i.e. the content that presents the perceptual object as having certain properties, does not determine the object of the experience. His account consequently does not require that the state of affairs that is presented in perception exists in order for the perception to have an object. Smith argues instead that perceptual reference is determined by a specific kind of demonstrative content. In this paper it is argued that Smith's account of demonstrative content is too indeterminate and in certain circumstances prescribes the wrong object. It is subsequently argued that the theory of demonstrative content can be modified so as to avoid these consequences. This modification involves deriving the conditions of satisfaction of seeing an object from the conditions of satisfaction of seeing the shape of the object, where the shape of the object is conceived of as a particularized property, what is also called a trope'.

    Time, Mode and Perceptual Content2012In: Acta Analytica, ISSN 0353-5150, E-ISSN 1874-6349, Vol. 27, no 4, p. 425-439Article in journal (Refereed)
    Abstract [en]

    Francois Recanati has recently argued that each perceptual state has two distinct kinds of content, complete and explicit content. According to Recanati, the former is a function of the latter and the psychological mode of perception. Furthermore, he has argued that explicit content is temporally neutral and that time-consciousness is a feature of psychological mode. In this paper it is argued, pace Recanati, that explicit content is not temporally neutral. Recanati's position is initially presented. Three desiderata for a theory of time-consciousness are subsequently introduced. It is then argued that a theory locating time-consciousness as a feature of psychological mode will fail to satisfy these desiderata. In the last section the intentionality of memories is discussed. Using the notion of shiftable indexical, it is argued that memories have the same explicit content as perceptions, but that they nevertheless can have different conditions of satisfaction since they are entertained in different modes.

    Two Kinds of Time-Consciousness and Three Kinds of Content2013In: Axiomathes, ISSN 1122-1151, E-ISSN 1572-8390, Vol. 23, no 1, p. 61-80Article in journal (Refereed)
    Abstract [en]

    This paper explores the distinction between perceiving an object as extended in time, and experiencing a sequence of perceptions. I argue that this distinction cannot be adequately described by any present theory of time-consciousness and that in order to solve the puzzle, we need to consider perceptual content as having three distinct constituents: Explicit content, which has a particular phenomenal character, modal content, or the kind of content that is contributed by the psychological mode, and implicit content, which lacks phenomenal character. These notions are then further clarified and related to each other.

    War, vagueness and hybrid war2019In: Defence Studies, ISSN 1470-2436, E-ISSN 1743-9698, Vol. 19, no 2, p. 189-204Article in journal (Refereed)
    Abstract [en]

    It has frequently been observed in the literature on hybrid wars that there is a grey zone between peace and war, and that hybrid wars are conflicts which are not clear cases of war. In this paper, I attempt to illuminate this grey zone and the concept and nature of war from the philosophical discussions of vagueness and institutional facts. Vague terms are characterized by the fact that there is no non-arbitrary boundary between entities which lie in their extension, and entities which do not lie in their extension. I apply a theory of vagueness to notions such as “war” and “peace” and go on to suggest that the exact boundary for what counts as a war or not is arbitrary. However, the context in which the conflict occurs determines a range of possible locations for this boundary. The most important contextual parameter is in this respect how the parties to the conflict themselves conceptualize the conflict. I suggest that this can in various ways help us understand grey-zone conflicts.

    Convergence analysis of multirate fixed-stress split iterative schemes for coupling flow with geomechanics2016In: Computer Methods in Applied Mechanics and Engineering, ISSN 0045-7825, E-ISSN 1879-2138, Vol. 311, p. 180-207Article in journal (Refereed)
    Abstract [en]

    We consider multirate iterative schemes for the Biot system modeling coupled flow and geomechanics in a poro-elastic medium. The multirate iterative coupling scheme exploits the different time scales for the mechanics and flow problems by taking multiple finer time steps for flow within one coarse mechanics time step. We adapt the fixed stress split algorithm that decouples the flow and mechanics equations for the multirate case and perform an iteration between the two problems until convergence. We provide a fully discrete scheme that uses Backward Euler time discretization and mixed spaces for flow and conformal Galerkin for mechanics. Our analysis is based on studying the equations satisfied by the difference of iterates and using Banach contraction argument to prove that the corresponding scheme is a fixed point contraction. The analysis provides the value of an adjustable coefficient used in the proposed iterative coupling algorithms. Furthermore, we show that the converged quantities satisfy the variational weak form for the coupled discrete system. (C) 2016 Elsevier B.V. All rights reserved.

    Stability of multirate explicit coupling of geomechanics with flow in a poroelastic medium2019In: Computers and Mathematics with Applications, ISSN 0898-1221, E-ISSN 1873-7668, Vol. 78, no 8, p. 2682-2699Article in journal (Refereed)
    Abstract [en]

    We consider single rate and multirate explicit schemes for the Biot system modeling coupled flow and geomechanics in a poro-elastic medium. These schemes are widely used in practice that follows a sequential procedure in which the flow and mechanics problems are fully decoupled. In such a scheme, the flow problem is solved first with time-lagging the displacement term followed by the mechanics solve. The multirate explicit coupling scheme exploits the different time scales for the mechanics and flow problems by taking multiple finer time steps for flow within one coarse mechanics time step. We provide fully discrete schemes for both the single and multirate approaches that use Backward Euler time discretization and mixed spaces for flow and conformal Galerkin for mechanics. We perform a rigorous stability analysis and derive the conditions on reservoir parameters and the number of finer flow solves to ensure stability for both schemes. Furthermore, we investigate the computational time savings for explicit coupling schemes against iterative coupling schemes.

    Abstract [en]

    In this paper, we consider an iterative coupling scheme for solving a fully discretized Biot system based on the fixed-stress split coupling algorithm. Specifically, we derive a priori error estimates for quantifying the error between the solution obtained at any iterate and the true solution. Our approach is based on studying the equations satisfied by the difference of iterates and utilizing a Banach contraction argument to show that the corresponding scheme is a fixed point iteration. Obtained contraction results are then used to derive theoretical convergence error estimates for the single rate iterative coupling scheme. We compare our numerical computations against the theoretically derived contraction estimates and show a good agreement with theory.

    Convergence of the undrained split iterative scheme for coupling flow with geomechanics in heterogeneous poroelastic media2019In: Computational Geosciences, ISSN 1420-0597, E-ISSN 1573-1499Article in journal (Refereed)
    Abstract [en]

    Recently, an accurate coupling between subsurface flow and reservoir geomechanics has received more attention in both academia and industry. This stems from the fact that incorporating a geomechanics model into upstream flow simulation is critical for accurately predicting wellbore instabilities and hydraulic fracturing processes. One of the recently introduced iterative coupling algorithms to couple flow with geomechanics is the undrained split iterative coupling algorithm as reported by Kumar et al. (2016) and Mikelic and Wheeler (Comput. Geosci. 17: 455–461 2013). The convergence of this scheme is established in Mikelic and Wheeler (Comput. Geosci. 17:455–461 2013) for the single rate iterative coupling algorithm and in Kumar et al. (2016) for the multirate iterative coupling algorithm, in which the flow takes multiple finer time steps within one coarse mechanics time step. All previously established results study the convergence of the scheme in homogeneous poroelastic media. In this work, following the approach in Almani et al. (2017), we extend these results to the case of heterogeneous poroelastic media, in which each grid cell is associated with its own set of flow and mechanics parameters for both the single rate and multirate schemes. Second, following the approach in Almani et al. (Comput. Geosci. 21:1157–1172 2017), we establish a priori error estimates for the single rate case of the scheme in homogeneous poroelastic media. To the best of our knowledge, this is the first rigorous and complete mathematical analysis of the undrained split iterative coupling scheme in heterogeneous poroelastic media.

    A study of residential radon in Sweden using multilevel analysis2008In: Health Physics Journal, to appear 2008Article in journal (Refereed)
    Abstract [en]

    A Swedish radon data set, consisting of more than 8000 measurements of residential radon levels in about 50% of the Swedish municipalities were analysed using a multilevel approach.

    The results were compared with those of a single-level analysis. We found that there was a significant variability between municipalities. The point estimates of the population mean radon levels were similar (geometric mean 60 Bq/m3 and arithmetic mean 106 Bq/m3).

    The analysis shows the advantages of multilevel modeling compared with a single-level OLS model.

    A single-level model results in too optimistic standard errors, about 25% of those of the multilevel

    model which can lead to erroneous conclusions.

    In a multilevel model including house type as a fixed effect (single-family house, row house, or apartment in multi-family house), the estimates of the fixed effect of house type were similar for the single-level and the multi-level models

    Abstract [en]

    This paper describes an alternative approach for testing for the existence of trend among time series. The test method has been constructed using wavelet analysis which has the ability of decomposing a time series into low frequencies (trend) and high-frequency (noise) components. Under the normality assumption, the test is distributed as F. However, using generated empirical critical values, the properties of the test statistic have been investigated under different conditions and different types of wavelet. The Harr wavelet has shown to exhibit the highest power among the other wavelet types. The methodology here has been applied to real temperature data in Sweden for the period 1850-1999. The results indicate a significant increasing trend which agrees with the 'global warming' hypothesis during the last 100 years.

    A wavelet-based panel unit-root test in the presence of an unknown structural break and cross-sectional dependency, with an application of purchasing power parity theory in developing countries2017In: Applied Economics, ISSN 0003-6846, E-ISSN 1466-4283, Vol. 49, no 21, p. 2096-2105Article in journal (Refereed)
    Abstract [en]

    This article introduces two different non-parametric wavelet-based panel unit-root tests in the presence of unknown structural breaks and cross-sectional dependencies in the data. These tests are compared with a previously suggested non-parametric wavelet test, the parameteric Im-Pesaran and Shin (IPS) test and a Wald type of test. The results from the Monte Carlo simulations clearly show that the new wavelet-ratio tests are superior to the traditional tests both in terms of size and power in panel unit-root tests because of its robustness to cross-section dependency and structural breaks. Based on an empirical Central American panel application, we can, in contrast to previous research (where bias due to structural breaks is simply disregarded), find strong, clear-cut support for purchasing power parity (PPP) in this developing region.

    An Illustration of the Causality Relation between Government Spending and Revenue Using Wavelets Analysis on Finish Data2003In: Journal of Applied Statistics, 2003, 30, 571-584Article in journal (Refereed)
    Abstract [en]

    Quarterly data for the period 1960:1 to 1997:2, conventional tests, a bootstrap simulation approach and a multivariate Rao's F-test have been used to investigate if the causality between government spending and revenue in Finland was changed at the beginning of 1990 due to future plans to create the European Monetary Union (EMU). The results indicate that during the period before 1990, the government revenue Granger-caused spending, while the opposite happened after 1990, which agrees better with Barro's tax smoothing hypothesis. However, when using monthly data instead of quarterly data for almost the same sample period, totally different results have been noted. The general conclusion is that the relationship between spending and revenue in Finland is still not completely understood. The ambiguity of these results may well be due to the fact that there are several time scales involved in the relationship, and that the conventional analyses may be inadequate to separate out the time scale structured relationships between these variables. Therefore, to investigate empirically the relation between these variables we attempt to use the wavelets analysis that enables us to separate out different time scales of variation in the data. We find that time scale decomposition is important for analysing these economic variables.

    Inte bara träd: hållbart mångbruk av skogslandskapet2004Collection (editor) (Refereed)
    Abstract [sv]

    Skogslandskapen - hur skall vi värdera dem? Ska de betraktas som rekreationsområden och kulturlandskap eller som arena för konflikter och dragkamp om olika resurser? Är skogsregionerna närande eller tärande? Vilka viktiga samband finns mellan skandinaviska och tropiska landskap?Detta är några av de teman som behandlas i denna spänannde bok om de många dimensionerna och resurserna som ryms i skogslandskapen. Boken ger nya och stimulerande aspekter på framtidsmöjligheterna för en hållbar utveckling för boreala skogslandskap. Den tar också upp det nödvändiga mångbruket av skogens resurser liksom den förändrade synen på människans roll i skogen. Och inte minst behandlas den ekologiska paradoxen att störningar behövs för att bevara skogens ekologiska mångfald.Boken är författad av samhällsvetare, miljöteknologer och ekologer inom den tvärvetenskapliga forskargruppen MiljöFocus vid Karlstads universitet.

    News Users’ (Dis)trust in Media Performance: Challenges to Sustainable Journalism in Times of Xenophobia2017In: What Is Sustainable Journalism?: Integrating the Environmental, Social, and Economic Challenges of Journalism / [ed] Peter Berglez, Ulrika Olausson and Mart Ots, Peter Lang Publishing Group, 2017, 1, p. 161-179Chapter in book (Other academic)
    Abstract [en]

    In this chapter, the sustainability of journalism is explored with interest in how users express trust and distrust towards professional news media. The challenges to the sustainability of journalism have social, financial and environmental tenets. The center of attention here is the social aspect of how users negotiate the end of journalism in society. Users have conflicting views on how professional news media perform, oscillating between if the responsibility of news media should be extended to coverage of conflicting issues or to enable citizens to share a common ground imprinted by solidarity. These aspects merge and manifest in news related to issues of xenophobia and solidarity. The changed financial prospects of the news industry coincide with the timing of globalization’s effects on the local scene, where people experience increasing hurdles across the world. The sustainability of journalism—considered crucial for democracy—is currently under substantial pressure. At the same time, living conditions are deteriorating around the world. People need to migrate to other societies that are becoming ever more polarized between xenophobia and solidarity. News covering this process is constructed within a professional value system that—for the sustainability of journalism—needs to be perceived as legitimate.

    Undoing Churnalism?: Users sharing local news on Facebook2017In: Digital Journalism, ISSN 2167-0811, E-ISSN 2167-082X, Vol. 5, no 8, p. 1060-1079Article in journal (Refereed)
    Abstract [en]

    This study investigates the types of information that users of a local news site share on Facebook. This issue relates to the idea of "churnalism", which concerns a form of weakened journalism that diminishes the ability to perform expected tasks in a democratic society. As a major social media platform, Facebook has acquired substantial influence over news dissemination, and therefore, scholarly focus needs to be directed to users as news disseminators. The manners by which users share news on Facebook indicate whether churnalism is promoted or abated through users’ interaction with online news. In this study, a quantitative content analysis illustrates how 348 news articles published on a local news site were shared 7266 times. The results show that concerns related to churnalism should be directed primarily to the fact that the news outlet only rarely provides users with opportunities to interact with serious or hard news, while lightweight news is frequently offered. Despite this, users abate churnalism in the sense that the news they prefer to share is news from in-house sources rather than from external sources. The news extensively shared covers changes in the vicinity, and health care, and has emerged from local and regional events.
