Utilities Policy | Year: 2012

This paper examines the voluntary electricity demand management decisions of commercial and industrial customers (at the firm and facility level) of an electric utility serving a United States Midwestern metropolitan area. Using standard probit analysis, we find that electricity costs are a major determinant of a firm's decision to voluntarily engage in demand management programs. Specifically, an additional $100,000 in electricity costs raises the probability of participation in an electricity demand management program by 0.3 percent. We also find that companies with multiple sites are 3.7 percent more likely to participate. In terms of demand management program participation, these results indicate a difference between organization and size that warrants further examination. © 2011 Elsevier Ltd.

This paper discusses the notion of medical archetype and the manner how the archetype elements are documented in hospital patient records. This is done by interpreting the archetypes as information extraction templates in automatic text analysis of clinical narratives. The extensive extraction experiments performed over thousands of anonymous discharge letters show the actual instantiation of the required and expected items in the narrative clinical documentation; in fact much tacit medical knowledge is implicitly presented in the real clinical texts. This fact suggests that the archetype approach to defaults and inheritance might need certain development. © 2013 Springer-Verlag.

Set-theoretic solutions of the Yang-Baxter equation form a meeting-ground of mathematical physics, algebra and combinatorics. Such a solution consists of a set X and a function r: X × X → X × X which satisfies the braid relation. We examine solutions here mainly from the point of view of permutation groups: a solution gives rise to a map from X to the symmetric group Sym(X) on X satisfying certain conditions, whose image we call a Yang-Baxter permutation group. Our results include new constructions based on strong twisted unions, with an investigation of retracts and the multipermutation level and the solvable length of the groups defined by the solutions; new results about decompositions of solutions of arbitrary cardinality into invariant subsets and decompositions and factorisations of the associated Yang-Baxter group as a product of groups of the solutions defined by these invariant subsets. In particular, we obtain strong decomposition results if the Yang-Baxter permutation group is abelian or the solution is of finite multipermutation level. © 2011 Springer-Verlag.

This paper presents a research prototype for temporal event information extraction from hospital discharge letters in Bulgarian. An algorithm for extraction of primitive events automatically sets markers for patients' complaints, drug treatment and diagnoses with precision about 90%. Specific domain knowledge is further used to generate compound events and to identify some relations between event time sequences. Absolute and relative time information enables ordering the generated compound events using semi-intervals and fuzzy logic. Some negated events are analyzed as well to better structure the patient history. © 2012 Springer-Verlag.

We consider partitions of the positive integer n whose parts satisfy the following condition. For a given sequence of non-negative numbers {bk } k≥1, a part of size k appears in exactly bk possible types. Assuming that a weighted partition is selected uniformly at random from the set of all such partitions, we study the asymptotic behaviour of the largest part Xn. Let D(s)=Σ k=1 ∞ bkk-s , s=σ+iy, be the Dirichlet generating series of the weights bk. Under certain fairly general assumptions, Meinardus (1954) obtained the asymptotic of the total number of such partitions as n→∞. Using the Meinardus scheme of conditions, we prove that Xn , appropriately normalized, converges weakly to a random variable having Gumbel distribution (i.e., its distribution function equals e-e -t , -∞

This study empirically examines the extent of environmental management practiced by US chemical manufacturing facilities, as reflected in the number of environmental internal audits conducted annually. As its focus, this study analyzes the effects of firm-level organizational structure on facility-level environmental management practices. For this empirical analysis, the study exploits unique data from a survey distributed to all U.S. chemical manufacturing permitted to discharge wastewater in 2001; the data reflect internal audits conducted during the years 1999-2001. Empirical results reveal differences in auditing behavior based on whether facilities are owned by publicly held or non-publicly held firms, owned by U.S.-based or non-U.S.-based firms, and owned by larger or smaller firms. © 2013 Elsevier Ltd.

In 1980, John Dunning has published an article on foreign direct investments and the level of a firm desire to be involved in the internationalization process, which in his view, depends on three factors: the location, ownership and internalization advantages. It should be noted that Dunning himself points out that while individual companies are used to illustrate the paradigm, its main focus is to explain international production by all firms in a country or group of countries. However, this article aims to analyze the effects of the internationalization process of Dow Chemicals, through the eclectic OLI Paradigm.

Records (PRs) in Bulgarian. The specific terminology and lack of resources in electronic format are some of the obstacles that make the task of current patient status data extraction in a structured format quite challenging. The usage of N-grams, collocations and words' distances allows us to cope with this problem and to extract automatically the attribute-value pairs with relatively high precision.

Firms producing seasonal goods often make order and production choices prior to highly uncertain sales, thus lending an investment quality to their decisions. Using specialized inputs imposes a delay in receiving them and linked with a long production period the firm makes its order, production and pricing choices under successively reduced uncertainty. The model shows that input and production costs have distinctive effects on the firm's order size with implications for the stock of raw materials inventory. Firms facing relatively low input costs are willing to risk leaving inputs unused as a bet for a good state of nature. Further, we investigate situations of greater uncertainty and find a more nuanced explanation of firm behavior than previous research. Firms with relatively inexpensive inputs facing equal odds of good and bad states of nature will increase their order size (a known result). However, a firm with a low relative cost of completing production may either raise or reduce its order size depending on the demand elasticity and the relative demand uncertainty. Intuitively, firms with expensive inputs facing highly uncertain demand and with many substitute output goods are inhibited by the high cost of insuring against stock-outs. © 2013 Elsevier B.V.
