Syntactic Optionality

AbstractThe aim of this paper is to corroborate the assumption of syntactic optionality for French wh-questions. In terms of a broader basis of evidence three different data types are utilized: Firstly, a qualitative interview approach suggests that wh-in-situ does not show the syntactic restrictions postulated by Bošković (1998) and Cheng & Rooryck (2000), weakening the evidence in favor of the assumption of LF-movement. Secondly, a graded grammaticality judgment test reveals that even in terms of fine nuances an identical level of grammaticality exists between the wh-in-situ form and its counterpart with wh-movement. Given the fact that several crucial judgments in the literature on French wh-in-situ are doubtful, these approaches turn out to be particularly helpful for controlling undesirable interferences in the judgment process and for obtaining more reliable data. Thirdly, a reading time study shows that both variants have the same cognitive complexity in processing. These empirical studies come along with methodological work concerning the development and evaluation of the instruments. From a conceptual point of view the inherent contradiction to which optionality and economy lead within the minimalist framework will be addressed. I will largely follow the suggestion of Haider & Rosengren (2003), who assume optional movement to be exploited at the interface level of syntax. Concerning the latter, I point out that different registers partly correlate with different French wh-questions.

Irradiation effects studies employing TEMs as analytical tools have been conducted for almost as many years as materials people have done TEM, motivated largely by materials needs for nuclear reactor development. Such studies have focussed on the behavior both of nuclear fuels and of materials for other reactor components which are subjected to radiation-induced degradation. Especially in the 1950s and 60s, post-irradiation TEM analysis may have been coupled to in situ (in reactor or in pile) experiments (e.g., irradiation-induced creep experiments of austenitic stainless steels). Although necessary from a technological point of view, such experiments are difficult to instrument (measure strain dynamically, e.g.) and control (temperature, e.g.) and require months or even years to perform in a nuclear reactor or in a spallation neutron source. Consequently, methods were sought for simulation of neutroninduced radiation damage of materials, the simulations employing other forms of radiation; in the case of metals and alloys, high energy electrons and high energy ions.

Positive Effect

Corruption is a key factor that affects countries’ development, with emerging countries being a geographical area in which it tends to generate greater negative effects. However, few empirical studies analyze corruption from the point of view of disclosure by companies in this relevant geographical area. Based on a regression analysis using data from the 96 large companies from 15 emerging countries included in the 2016 International Transparency Report, this paper seeks to understand what determinants affect such disclosure. In that context, this paper provides empirical evidence to understand the factors that influence reporting on anti-corruption mechanisms in an area of high economic importance that has been little studied to date, pointing to the positive effect of press freedom in a country where the company is located and with the industry being the unique control variable that strengthens this relationship.

Viking missions reported adverse conditions for life in Mars surface. High hydrogen signal obtained by Mars orbiters has increased the interest in subsurface prospection as putative protected Mars environment with life potential. Permafrost has attracted considerable interest from an astrobiological point of view due to the recently reported results from the Mars exploration rovers. Considerable studies have been developed on extreme ecosystems and permafrost in particular, to evaluate the possibility of life on Mars and to test specific automated life detection instruments for space missions. The biodiversity of permafrost located on the Bering Land Bridge National Preserve has been studied as an example of subsurface protected niche of astrobiological interest. Different conventional (enrichment and isolation) and molecular ecology techniques (cloning, fluorescence“in situ”probe hybridization, FISH) have been used for isolation and bacterial identification.

We have investigated the feasibility of using high-molecular-weight polysaccharides produced by marine microalgae to reduce the drag on ships and therefore to be able to reduce the needed propulsion power and fuel costs or, alternatively, to increase the ship speed. Experimental and analytical studies were used to answer four critical questions:How suitable are the biopolymers for drag reduction on ships?What is the needed polymer consumption rate at a given level of drag reduction?What is the achievable polymer production rate that can be achieved by the microalgae?What are possible modes of implementation of the proposed technology? It is seen that in situ production of biopolymers by microalgae growing on the hull may be a possible approach to polymeric ship drag reduction. Production of biopolysaccharide off the ship and even harvesting it from the ocean are other possibilities. The use of biopolymers is naturally advantageous from an environmental point of view as well. Some comparison of biopolymers and synthetic polymers is also presented. Several technical issues remain to be investigated, but the information available suggests that biopolymers may be the best additives for drag reduction on ships.

This work is focused on the diagnosis of behavior, from the point of view of control emissions and noise level, of a power Turbogas plant during the process of commissioning, to guarantee that its operation complies with national and international standards. The environmental diagnosis of the power plant was developed as part of the performance evaluation of the unit. The conditions of the unit evaluation include operation at base load and partial load, as well as time periods for load changes. The evaluated power plant consists of an aeroderivative gas turbine installed in a simple cycle, operating with a cooling system (chiller) installed in the urban zone of Mexico City. Therefore, it should comply with the legislation and regulations of the city concerning air pollution and allowed noise, besides the international standards established by the manufacturer. The study includes emissions measurements using a Continuous Emissions Monitoring System installed in-situ, previously calibrated and checked during and after the test which was found inside the permissible deviation of 3%. Measurements were recorded at intervals of 5 minutes during test periods of 110 minutes for each load and 45 minutes for load changes. On the other hand, noise pressure evaluation was carried out in near field as well as far field produced by the power plant during operation. Measurements were carried out by using precision instruments installed specifically for it. A temporary system for obtaining data was used to monitoring the environmental conditions every 30 seconds. It was possible to verify that the turbogenerator complies with all noise levels and contaminant emissions requirements and regulations according to the limits established by the manufacturer and national and international standards.

We address the process of discounting in random environments which allows to value the far future in economic terms. We review several approaches to the problem regarding different well-established stochastic market dynamics in the continuous-time context and include the Feynman-Kac approach. We also review the relation between bond pricing theory and discount and introduce the market price of risk and the risk neutral measures from an intuitive point of view devoid of excessive formalism. We provide the discount for each economic model and discuss their key results. We finally present a summary of our previous empirical studies on several countries of the long-run discount problem.

Wh Questions

Theories of pair-list readings of multiple wh-questions commonly posit an interpretive asymmetry between the fronted and in-situ wh-phrases, where the fronted wh-phrase is argued to function as the sortal key, have a requirement to be interpreted exhaustively, or be obligatorily D-linked. To clarify the empirical landscape of such debate, I present three experiments which tease apart the effects of these often-confounded discourse factors on the order and interpretation of multiple wh-questions. They are found to have either inconsistent or insignificant effects, arguing against a unique discourse-sensitivity of the fronted wh-phrase. Theories of questions which encode such an asymmetry should accordingly be revised.

Wh Questions

In this article, an empirical study of how Chinese wh-questions are mentally represented in Japanese speakers' grammars of Chinese as a second language (L2) is reported. Both Chinese and Japanese are generally considered wh-in-situ languages in which a wh-word is allowed to remain in its base-generated position, and both languages use question particles to mark questions. It is assumed that C0 in wh-questions is essentially ambiguous and unvalued and that unvalued C0 must be valued. In Chinese, the wh-particle ne values C0 with [+Q, +wh] features, which licenses the wh-word in situ. As a result, no wh-movement is necessary and Subjacency becomes irrelevant. Japanese also employs question particles, such as ka or no. However, they are `defective' in the sense that they can only value the ambiguous C0 as [+Q] and they are unable to specify the question as to whether it is [+yes/no] or [+wh]. To value C0 as a head with [+wh], a wh-operator in a wh -word inside the sentence has to raise overtly to C0. The results of an acceptability judgement task show that although the Japanese speakers respond in a broadly target-like way, the lexical morphological feature [+wh] of the particle ne in their L2 Chinese lexicons is permanently deficient, which leads to variability in their intuitions about Chinese wh-questions. A lexical morphological feature deficit account for the results is proposed, and it is suggested that the lexical morphology—syntax interface can be a source of variability in L2 acquisition.

Diverse Data

<p>The study of the earth’s systems depends on a large amount of observations from homogeneous sources, which are usually scattered around time and space and are tightly intercorrelated to each other. The understanding of said systems depends on the ability to access diverse data types and contextualize them in a global setting suitable for their exploration. While the collection of environmental data has seen an enormous increase over the last couple of decades, the development of software solutions necessary to integrate observations across disciplines seems to be lagging behind. To deal with this issue, we developed the Digital Earth Viewer: a new program to access, combine, and display geospatial data from multiple sources over time.</p><p>Choosing a new approach, the software displays space in true 3D and treats time and time ranges as true dimensions. This allows users to navigate observations across spatio-temporal scales and combine data sources with each other as well as with meta-properties such as quality flags. In this way, the Digital Earth Viewer supports the generation of insight from data and the identification of observational gaps across compartments.</p><p>Developed as a hybrid application, it may be used both in-situ as a local installation to explore and contextualize new data, as well as in a hosted context to present curated data to a wider audience.</p><p>In this work, we present this software to the community, show its strengths and weaknesses, give insight into the development process and talk about extending and adapting the software to custom usecases.</p>

Object Oriented Metrics

This chapter presents the analysis of ten recently proposed object-oriented metrics based on cognitive informatics. The metrics based on cognitive informatics use cognitive weight. Cognitive weight is the representation of the understandability of the piece of software that evaluates the difficulty experienced in comprehending and/or performing the piece of software. Development of metrics based on Cognitive Informatics (CI) is a new area of research, and from this point of view, for the analysis of these metrics, it is important to know their acceptability from other existing evaluation and validation criteria. This chapter presents a critical review on existing object-oriented cognitive complexity measures. In addition, a comparative study based on some selected attributes is presented.
