Research into second language (L2) reading is an exponentially growing field. Yet, it still has a relatively short supply of comparable, ecologically valid data from readers representing a variety of first languages (L1). This article addresses this need by presenting a new data resource called MECO L2 (Multilingual Eye Movements Corpus), a rich behavioral eye-tracking record of text reading in English as an L2 among 543 university student speakers of 12 different L1s. MECO L2 includes a test battery of component skills of reading and allows for a comparison of the participants’ reading performance in their L1 and L2. This data resource enables innovative large-scale cross-sample analyses of predictors of L2 reading fluency and comprehension. We first introduce the design and structure of the MECO L2 resource, along with reliability estimates and basic descriptive analyses. Then, we illustrate the utility of MECO L2 by quantifying contributions of four sources to variability in L2 reading proficiency proposed in prior literature: reading fluency and comprehension in L1, proficiency in L2 component skills of reading, extralinguistic factors, and the L1 of the readers. Major findings included (a) a fundamental contrast between the determinants of L2 reading fluency versus comprehension accuracy, and (b) high within-participant consistency in the real-time strategy of reading in L1 and L2. We conclude by reviewing the implications of these findings to theories of L2 acquisition and outline further directions in which the new data resource may support L2 reading research.
Airborne radio-echo sounding (RES) surveys are widely used to measure ice-sheet bed topography. Measuring bed topography as accurately and widely as possible is of critical importance to modelling ice dynamics and hence to constraining better future ice response to climate change. Measurement accuracy of RES surveys is influenced both by the geometry of bed topography and the survey design. Here we develop a novel approach for simulating RES surveys over glaciated terrain, to quantify the sensitivity of derived bed elevation to topographic geometry. Furthermore, we investigate how measurement errors influence the quantification of glacial valley geometry. We find a negative bias across RES measurements, where off-nadir return measurement error is typically −1.8 ± 11.6 m. Topographic highlands are under-measured an order of magnitude more than lowlands. Consequently, valley depth and cross-sectional area are largely under-estimated. While overall estimates of ice thickness are likely too high, we find large glacier valley cross-sectional area to be under-estimated by −2.8 ± 18.1%. Therefore, estimates of ice flux through large outlet glaciers are likely too low when this effect is not taken into account. Additionally, bed mismeasurements potentially impact our appreciation of outlet-glacier stability.
Pleasure and displeasure have been suffering from intellectual neglect in the philosophy of mind. In contemporary work, the mode of experience which effectively dominates discussion is vision—David Marr's work on visual representation and L. Weiskrantz's work on blindsight are familiar to many philosophers of mind, as are the philosophical uses of such work, and no one seems to tire of working out what the frog's eye tells the frog's brain. Who, though, can name a leading theorist of pain? As a source of examples and intuitions, pain is a perennial favorite in ethics and the philosophy of mind, but in both disciplines pain is taken for granted far more often than it is the object of analysis. Equally significantly, forms of displeasure other than pains are very largely neglected. Pleasure, for its part, has been the nigh-exclusive province of moral theorists; few other than Strawson seem to have taken a special interest in it in the philosophy of mind. The object of the present work is to rectify this neglect, and to give an account of pleasure and displeasure which reveals a striking degree of unity and theoretical tractability underlying the diverse phenomena: a representationalist account.
Picture a heroin addict of the sort frequently found in philosophical work on freedom and responsibility. In Harry Frankfurt's terms, she is an unwilling addict. She wishes she were not an addict, has attempted to break her addiction but failed, and hopes to escape from the demands of the drug — but in spite of her will to resist, she satisfies her craving in the end. The unwilling addict does not merely have a conflict of desires: she experiences herself as surrendering to a desire which is not really hers, a desire with respect to which she feels a passive observer or an active opponent. Her desire strikes her as alien, incomprehensible. There are at least two striking features of such an addict. The first is what we will call her akrasia.(We use the term ‘akrasia’ here in a broad sense, to mean ‘ acting against one's better judgment,’ and assume for this paper that akrasia in this form exists.) Her better judgment recommends not taking heroin, indeed ending the habit, yet she takes heroin anyway. The second is what we will call her alienation from her desire to use the drug.
Late Holocene sediment deposits in Pine Island Bay, West Antarctica, are hypothesized to be linked to intensive meltwater drainage during the retreat of the paleo-Pine Island Ice Stream after the Last Glacial Maximum. The uppermost sediment units show an abrupt transition from ice-proximal debris to a draped silt during the late Holocene, which is interpreted to coincide with rapid deglaciation. The small scale and fine sorting of the upper unit could be attributed to origins in subglacial meltwater; however the thickness and deposition rate for this unit imply punctuated- rather than continuous-deposition. This, combined with the deposit's location seaward of large, bedrock basins, has led to the interpretation of this unit as the result of subglacial lake outbursts in these basins. However, the fine-scale sorting of the silt unit is problematic for this energetic interpretation, which should mobilize and deposit a wider range of sediment sizes. To resolve this discrepancy, we present an alternative mechanism in which the silt was sorted by a distributed subglacial water system, stored in bedrock basins far inland of the grounding line, and subsequently eroded at higher flow speeds during retreat. We demonstrate that this mechanism is physically plausible given the subglacial conditions during the late Holocene. We hypothesize that similar silt units observed elsewhere in Antarctica downstream of bedrock basins could be the result of the same mechanism.
The 1992 Convention on Biological Diversity (CBD) and its 2010 Nagoya Protocol brought about a breakthrough in global policy making. They combined a concern for the environment with a commitment to resolving longstanding human injustices regarding access to, and use of biological resources. In particular, the traditional knowledge of indigenous communities was no longer going to be exploited without fair benefit sharing. Yet, for 25 years after the adoption of the CBD, there were no major benefit sharing agreements that led to significant funding streams for indigenous communities. This changed with the signing of the Rooibos Benefit Sharing Agreement in South Africa, described in this paper. As the authors report, the Rooibos Agreement is a superlative in two respects. It is the biggest benefit sharing agreement between industry and indigenous peoples to date. It is also the first industry-wide agreement to be formed in accordance with biodiversity legislation. This article is a co-production between traditional knowledge holders, the lawyer who represented their interests, the Co-Chair of the Nagoya Protocol negotiations, and an ethicist who analyzed the major challenges of this historic agreement. With no precedent in the benefit sharing world, the agreement stands as a concrete example of the ‘art of the possible.’ Although the rooibos case is unique in a number of aspects, the experience offers many transferable insights, including: patience; incrementalism; honesty; trust; genuine dialogue; strong legal support; a shared recognition that a fair, win-win deal is possible; government leadership; and unity amongst indigenous peoples. Such ingredients of success can apply well beyond southern Africa.
Philosophers often talk about and engage with ideas. Scientists, artists, and historians do, too. But what is an idea? In this paper, we first motivate the desire for an ontology of ideas before discussing what conditions a candidate ontology would have to satisfy to be minimally adequate. We then offer our own account of the ontology of ideas and consider various strategies for specifying the underlying metaphysics of the account. We conclude with a discussion of potential future work to be done on the ontology of ideas.
As topics in the philosophy of emotion, pleasure and displeasure get less than their fair share of attention. On the one hand, there is the fact that pleasure and displeasure are given no role at all in many theories of the emotions, and secondary roles in many others. On the other, there is the centrality of pleasure and displeasure to being emotional. A woman who tears up because of a blustery wind, while an ill-advised burrito weighs heavily upon her digestive tract, feels an impressive number of the sensations felt by someone who is gut-wrenchingly sad. Yet, unless she feels bad, the way she feels is only a pale echo of the feeling of sadness. If she feels good in spite of the burrito and the wind, then she does not feel at all the way she would if she were sad. Likewise, a man falling asleep can hardly fail to feel his muscles relax, his heart rate fall, and so on, but unless he feels good his state is only a shadow of feeling content.
We investigated the use of a pulsed excimer laser having a wavelength of 248 nm, a pulse duration of 38 ns, and an average fluence between 120 and 780 mJ/cm2 to locally tailor the physical properties of Si1−xGex (18% < x < 90%) films deposited by low-pressure chemical vapor deposition at temperatures between 400 and 450 °C. Amorphous as-deposited films showed, after laser annealing, strong {111} texture, a columnar grain microstructure, and an average resistivity of 0.7 mΩ cm. Atomic force microscopy indicated that the first few laser pulses resulted in a noticeable reduction in surface roughness, proportional to the pulse energy. However, a large number of successive pulses dramatically increased the surface roughness. The maximum thermal penetration depth of the laser pulse is demonstrated to depend on the fluence and the film structure being either polycrystalline or amorphous. Finally, a comparison between excimer laser annealing and metal-induced crystallization and rapid thermal annealing is presented.
In this work, we investigate the possibility of using pulsed laser annealing to locally tailor the physical properties of Si1-xGex (18% < × < 90%) prepared by low pressure chemical vapor deposition (LPCVD) at 400°C. Films which were amorphous as deposited showed, after laser annealing, strong {111} texture and a columnar grain microstructure and an average resistivity of 0.7 mΩ.cm. AFM showed that the first few laser pulses result in a noticeable reduction in surface roughness, which is proportional to the pulse energy. However, a large number of successive pulses dramatically increases the surface roughness.
There are monsters that scare children and monsters that scare grownups, and then there are monsters that scare philosophers of mind. This paper is concerned with this third sort of monster, whose primary representative is the zombie – a living being, physically just like a person but lacking consciousness. Though zombies act like normal people and appear to have normal brains, everything is blank inside. Unfortunately, the term ‘zombie’ covers a narrower class of deficits than is convenient, failing to cover apparently normal human beings lacking propositional attitudes. Davidson's (1987) “Swampman” is supposed to be an example of such a creature, so I will dub individuals who are apparently normal but lack all propositional attitudes ‘swampfolk,’ though this is non-standard terminology. In what follows, I will refer to both zombies and swampfolk as ‘monsters,’ and will similarly designate animals lacking in consciousness or propositional attitudes.
