This chapter provides a systematic comparison of plural logic and an atomistic version of classical mereology. Since these two systems are mutually interpretable, it is formally possible to eliminate one in favor of the other. However, reasons are offered to retain both systems. In particular, mereology is a useful tool for the analysis of plurals in natural language.

Evans and Over (1996) made a seminal contribution to the cognitive sciences by describing two different routes humans take to reason toward their goals, one associated with intuition, the other with deliberation. We show how knowledge provided by our communities influences both routes. Many methods of outsourcing cognitive effort– taking advantage of information that one does not know but assumes that someone else can supply—show the hallmarks of intuitive reasoning. Effective outsourcing requires fast and efficient ways of identifying what must be outsourced, and which individual or group of people is most likely to have the relevant expertise. Research has identified several fallible heuristics like the degree of entrenchment of a term in a community of use that help people figure out what needs to be outsourced (content heuristics), and a different group of heuristics that allow us to find experts, for instance, through associations with certain environments and disciplines (expertise heuristics). In contrast, deliberation is primarily concerned with facilitating intentional collaboration with others toward joint goals, often using natural language. This division of labor between two interacting but distinct systems allows humans to leverage the representational and computational capacities of their communities to achieve ever more sophisticated goals.

In this paper, the changes in the US automobile industry which have occurred over the 1979–86 economic downturn and recovery are examined within the framework of Markusen's profit-cycle theory. When viewing the automobile indusltry as a whole, some of the findings support the profit-cycle theory and others do not. The theory is supported, however, within the context of two distinct automobile industries in the USA—one ‘Fordist’ and the other a Japanese ‘post-Fordist’ system. The Fordist system is entering the negative profit-cycle phase and the post-Fordist system is in the mature phase. The two systems have very different spatial configurations and are likely to have very different economic futures.

This study questions the utility of classifying all juvenile offenders under the single rubric of “delinquent.” It presents two systems for classifying offenders according to the delinquent act. The first is a rating scale for severity. Correlations among the ratings of 13 judges ranged from .56 to 93, with a mean of .77. 10 judges rated direction of aggression—against people, against property, general asocial. The percentages of items on which each judge agreed with each of the other judges ranged from 70 to 97. 34 offenses were rated, and a 9- and a 5-point scale of severity are presented.

The growth of phases by reactive diffusion in Mo-Si and W-Si systems are compared. The crystal structures of MSi2 and M5Si3 phases (M = Mo, W) are similar in these two systems. However, the diffusion rates of the components change systematically with a change in the atomic number. Integrated diffusion coefficients in both phases increase with an increasing atomic number of refractory elements i.e. from Mo to W. On the other hand, the ratio of diffusivities of the components decreases. This indicates a relative increase in the diffusion rates of the metal components with increasing atomic number and a difference in defects concentrations in these two systems.

ABSTRACT Microphysical and thermodynamical features of two tropical systems, namely Hurricane Ivan and Typhoon Conson, and one sub-tropical, Catarina, have been analyzed based on space-born radar PR measurements available on the TRMM satellite. The procedure to classify the reflectivity profiles followed the Heymsfield et al (2000) and Steiner et al (1995) methodologies. The water and ice content have been calculated using a relationship obtained with data of the surface SPOL radar and PR in Rondonia State in Brazil. The diabatic heating rate due to latent heat release has been estimated using the methodology developed by Tao et al (1990). A more detailed analysis has been performed for Hurricane Catarina, the first of its kind in South Atlantic. High water content mean value has been found in Conson and Ivan at low levels and close to their centers. Results indicate that hurricane Catarina was shallower than the other two systems, with less water and the water was concentrated closer to its center. The mean ice content in Catarina was about 0.05 g kg-1 while in Conson it was 0.06 g kg-1 and in Ivan 0.08 g kg-1. Conson and Ivan had water content up to 0.3 g kg-1 above the 0ºC layer, while Catarina had less than 0.15 g kg-1. The latent heat released by Catarina showed to be very similar to the other two systems, except in the regions closer to the center.

ABSTRACT The behaviour of two "meiotic drive" systems, Segregation-Distorter (SD) and the sex chromosome sc4sc8 has been examined in the same meiocyte. It has been found that the two systems interact in a specific way. When the distorting effects of SD and sc4sc8 are against each other, there is no detectable interaction. Each system is apparently oblivious to the presence of the other, gametes being produced according to independence expectations. However when the affected chromosomes are at the same meiotic pole an interaction occurs; the survival probability of the gamete containing both distorted chromosomal products is increased, rather than being decreased by the combined action of two systems.

While most approaches to the semantics of tense have attempted to regiment tense away in a tenseless metalanguage, a good case can be made that this is not without cost (the same case could be made for regimentation of modality and other aspects of natural language as well). On the other hand, it is pretty clear that attempts to treat tense in a tensed metalanguage introduce serious complications. It is probably not so important which of these positions is correct at this point (we may be some distance from resolving that question), as it is that we understand the costs of the respective positions. Perhaps, by having a firm enough grasp on both approaches we afford ourselves a deeper insight into the nature of tense itself.

Scripting is a widely-used way to automate the execution of tasks. Despite the popularity of scripting, it remains difficult to use for both beginners and experts: because of the cryptic commands for the first group, and incompatible syntaxes across different systems, for the latter group. The authors introduce Natural Shell, an assistant for enabling end-users to generate commands and scripts for various purposes. Natural Shell automatically synthesizes scripts for different shell systems based on natural language descriptions. By interacting with Natural Shell, new users can learn the basics of scripting languages without the obstacles from the incomprehensible syntaxes. On the other hand, the authors' tool frees more advanced users from manuals when they switch shell systems. The authors have developed a prototype system and demonstrate its effectiveness with a benchmark of 50 examples of popular shell commands collected from online forums. In addition, the authors analyzed the usage of Natural Shell in a lab study that involves 10 participants with different scripting skill levels. Natural Shell effectively assists the users to generate commands in assigned syntaxes and greatly streamlines their learning and using experience.

<p>Civil liability, contractual liability, and unconventional have two branches. If there is a contract between two or more persons and one of them committed a breach of contract (failure to perform, delay in performing the obligation) to and to harm the other party is incomplete and should the contract have contractual liability for damages cope. Where does harm to another person without a contract exists between them or if there is a contract, Inflict losses not related to the contract, the talk of non-contractual liability.</p><p>About whether contractual and non-contractual obligations is two different legal system or single legal system form, there is disagreement among the lawyers: Some distinguish these two systems from each other. But others believe that because the purpose of civil liability is to compensate for losses, these two are the single legal system.</p>By examining the different opinions, we see that both contractual and non-contractual liability system distinct from each other. And despite the contract, the victim can rely on the rules of non-contractual liability.

The nomenclature of the genus Salmonella has reached an unsatisfactory state of affairs, with two systems of nomenclature in circulation. One system, proposed in the 1980s by Le Minor and Popoff, has received wide acceptance, although it does not conform to the rules of the Bacteriological Code. The other system, which conforms to the rules of the Bacteriological Code, is being used by an ever-decreasing minority. As a result of a number of recent Requests for an Opinion, the Judicial Commission of the International Committee on the Systematics of Prokaryotes has issued an Opinion (Opinion 80) with the intention that it should solve these discrepancies. However, like all Opinions, it is limited to matters of nomenclature and does not help to interpret the taxonomic consequences. The Judicial Commission has therefore asked experts in the field of nomenclature and taxonomy to write a commentary on the nomenclatural and taxonomic consequences of Opinion 80. The present article explains the nomenclatural consequences of Opinion 80, together with a clear presentation of the taxonomy that results when applying the currently widely accepted interpretation that the genus Salmonella currently includes only two species.
