The paper focuses on a theoretical overview of the issue of executive functions in children with ASD. It explains the basic connections between deficits / dysfunctions in the area of executive functions and the manifestations of a child with ASD. These are also based on findings from several research studies. It also offers an overview of opportunities, programs and approaches to support individual executive functions.

We investigate the quantum geometry of a 2d surface S bounding the Cauchy slices of a 4d gravitational system. We investigate in detail for the first time the boundary symplectic current that naturally arises in the first-order formulation of general relativity in terms of the Ashtekar–Barbero connection. This current is proportional to the simplest quadratic form constructed out of the pull back to S of the triad field. We show that the would-be-gauge degrees of freedo arising from S U ( 2 ) gauge transformations plus diffeomorphisms tangent to the boundary are entirely described by the boundary 2-dimensional symplectic form, and give rise to a representation at each point of S of S L ( 2 , R ) × S U ( 2 ) . Independently of the connection with gravity, this system is very simple and rich at the quantum level, with possible connections with conformal field theory in 2d. A direct application of the quantum theory is modelling of the black horizons in quantum gravity.

abstract: This is the first step in an attempt at a deformation theory for $G_{2}$-instantons with $1$-dimensional conic singularities. Under a set of model data, the linearization yields a Dirac operator $P$ on a certain bundle over $\mathbb{S}^{5}$, called the \textit{link operator}. As a dimension reduction, the link operator also arises from Hermitian Yang--Mills connections with isolated conic singularities on a Calabi--Yau $3$-fold. Using the quaternion structure in the Sasakian geometry of $\mathbb{S}^{5}$, we describe the set of all eigenvalues of $P$, denoted by $\Spec P$. We show that $\Spec P$ consists of finitely many integers induced by certain sheaf cohomologies on $\mathbb{P}^{2}$, and infinitely many real numbers induced by the spectrum of the rough Laplacian on the pullback endomorphism bundle over $\mathbb{S}^{5}$. The multiplicities and the form of an eigensection can be described fairly explicitly. In particular, there is a relation between the spectrum on $\mathbb{S}^{5}$ to certain sheaf cohomologies on~$\mathbb{P}^{2}$. Moreover, on a Calabi--Yau $3$-fold, the index of the linearized operator for admissible singular Hermitian Yang--Mills connections is also calculated, in terms of these sheaf cohomologies. Using the representation theory of $\SU(3)$ and the subgroup $S[U(1)\times U(2)]$, we show an example in which $\Spec P$ and the multiplicities can be completely determined.

We prove that the word problem for the free product with amalgamation S *UT of monoids can be undecidable, even when S and T are finitely presented monoids with word problems that are decidable in linear time, the factorization problems for U in each of S and T, as well as other problems, are decidable in polynomial time, and U is a free finitely generated unitary submonoid of both S and T. This is proved by showing that the equality problem for the tensor product S ⊗UT is undecidable and using known connections between tensor products and amalgams. We obtain similar results for semigroups, and by passing to semigroup rings, we obtain similar results for rings as well. The proof shows how to simulate an arbitrary Turing machine as a communicating pair of two deterministic pushdown automata and is of independent interest. A similar idea is used in a paper by E. Bach to show undecidability of the tensor equality problem for modules over commutative rings.

For some classes of analytic functions f and 1 in the open unit disk U, we consider the general integral operatorMn, that was introduced in a recent work [2] and we obtain new conditions of univalence for this integral operator. The key tools in the proofs of our results are the Pascu?s and the Pescar?s univalence criteria. Some corollaries of the main results are also considered. Relevant connections of the results presented here with various other known results are briefly indicated.

This paper analyzes the connections between sexual violence and colonialism in the lives and histories of Native peoples in the United States. This paper argues that sexual violence does not simply just occur within the process of colonialism, but that colonialism is itself structured by the logic of sexual violence. Furthermore, this logic of sexual violence continues to structure U. S. policies toward Native peoples today. Consequently, anti-sexual violence and anti-colonial struggles cannot be separated.

A painting of the Virgin and Child, signed as “OPVUS P. PETRI”, from the former Fareham Collection (today at the Courtauld Institute of Art), has been known in the scholarly literature for a long time but has only been subject to tangential analyses. These studies attempted to attribute it to painters meeting relatively dubious criteria: that their name was Peter (Petar) and that they could be linked to the painting circle of Squarcione or, more specifically, to that of Carlo Crivelli with whose early works, especially the Virgin and Child (the Huldschinsky Madonna) at the Fine Arts Gallery in San Diego, the Courtauld painting shares obvious connections. Roberto Longhi ascribed it to the Paduan painter Pietro Calzetta in 1926, while Franz Drey, in 1929, considered it to be the work of Pietro Alemanno, Crivelli’s disciple, who worked in the Marche region during the last quarter of the fifteenth century. After the Second World War, the Courtauld painting was almost completely ignored by the experts. The only serious judgement was that expressed by Pietro Zampetti, who established that it was an almost exact copy of Crivelli’s Huldschinsky Madonna, meaning that if Calzetti had painted it, he would have done it while Carlo was still in the Veneto, before he went to Zadar.The search for information which can shed more light on the attribution of the Virgin and Child from the Courtauld is aided by the valuable records in the Fondazione Federico Zeri at the Università di Bologna. The holdings of the Fototeca Zeri include three different photographs of the Courtauld painting with brief but useful accompanying notes. Of particular importance is the intriguing inscription on the back of one of the photographs, which points to the painting’s Dalmatian origin. In a certain way, this opens the possibility that it might be linked to another painter who was close to the Crivelli brothers: the Zadar priest and painter Petar Jordanić. That he may have been the one who painted it is indicated by the signature itself, which could be read as “OPVUS P(RESBITERI) PETRI”.Archival records about Petar Jordanić provide almost no information about his work as a painter. Apart from his signature of 1493 on a no-longer extant polyptich from the Church of St Mary at Zadar, the only record of his artistic activities is one piece of information: that in 1500 he took part in a delegation which was sent from Zadar to its hinterland charged with the task of making drawings of the terrain which could be used to help defend the town against the Ottoman Turks. However, more than thirty documents which mention him do paint a picture of his life’s journey and his connection with Zadar. The most important basis for any consideration of a possible connection between Petar Jordanić and Carlo Crivelli can be found in the will of his father Marko Jordanov Nozdronja (in late 1468) where Petar was named as the executor, meaning that at this point he was of age. Therefore, it can be concluded that he was born between 1446 and 1448. This makes him old enough to have been taught by Carlo during his stay in Zadar from c. 1460 to 1466. Although relatively modest, the oeuvre of Petar Jordanić demonstrates striking connections with the paintings of Carlo and Vittore Crivelli, and Ivo Petricioli has already put forward a hypothesis that he may have been taught by one of the brothers.The comparison between the painting from the Courtauld Institute of Art in London and the known works of Petar Jordanić (the Virgin and Child from a private collection in Vienna; the Virgin and Child from the Parish Church at Tkon; fragments of a painted ceiling from Zadar Cathedral; the lost polyptich from the Church of St Mary at Zadar) reveals a multitude of similar features. Apart from the general resemblance in the physiognomies of the Virgin and Christ Child which represent the most conspicuous analogies, a number of very specific “Morellian” elements can also be noted in the manner in which the faces were painted. These similarities are particularly apparent when one compares the head of the Christ Child on the painting from London and his head on the one from Tkon, which are almost identically depicted. Further similarities between the London painting and the one at Vienna can be seen in the way in which landscapes were painted and in the similar decorations of the gold fabrics in the backgrounds with their undulating scrolls and sharp almond-shaped leaves.However, with regard to visual characteristics, it is apparent at first sight that the quality of the London painting is markedly higher and that it is stylistically more advanced than those works which are attributed with certainty to Jordanić. These differences can be explained by the possibility that this was a more or less direct copy of one of Carlo Crivelli’s painting, probably not the Huldschinsky Madonna but one that was very similar to it and subsequently lost.Naturally, if the London painting is attributed to Petar Jordanić, meaning that it was produced in Zadar, then the argument on the basis of which the Huldschinsky Madonna has been dated to the time before Crivelli’s arrival in Zadar becomes a counter-argument, and, in that way, corroborates the possibility that the Huldschinsky Madonna, which shares a large number of similar elements with the painting from the Courtauld Institute of Art, was created while Carlo was in Zadar.

In this paper, dense families of relation schemes are introduced. We characterize minimal keys of relation schemes in terms of dense families. Note that, the dense families of database relations were introduced by Jarvinen [6]. We prove that the set of all minimal keys of a relation scheme s= (U, F) is the transversal hypergraphs of a hypergraph D– {∅}, where Dis any s-dense family. We give a necessary and sufficient condition for an abitrary family to be s-dense family. We also present some dense families of relation schemes. Furthermore, in this paper, we also study antikeys by means of dense families. We present connections between antikeys and a dense family of relation schemes. Finally, we study the time complexity of the problem finding antikeys.

In the present investigation, with motivation from the pioneering work of Srivastava et al. [28], which in recent years actually revived the study of analytic and bi-univalent functions, we introduce the subclasses T*?(n,?) and T?(n,?) of analytic and bi-univalent function class ? defined in the open unit disk U = {z ? C : |z| < 1g and involving the S?l?gean derivative operator Dn. Moreover, we derive estimates on the initial coefficients |a2| and |a3| for functions in these subclasses and pointed out connections with some earlier known results.

This chapter describes Anna Botsford and John Henry Comstock's life in Washington, the entomologists who worked with the Comstocks there, and their social connections. On May 1, 1879, Henry became the U.S. Commissioner of Agriculture. Thus, he entered upon his duties as entomologist to the Department of Agriculture and into a very cordial association with Commissioner William G. Le Duc. Following his appointment, Henry asked for a two-year leave of absence from Cornell University. This was granted on the condition that he return for a fortnight in May to complete his course of lectures. As soon as they were settled in Washington, Anna went to Henry's office every day to help him with the many details of the department. As a result of this, she was offered a position to work for her husband.

Scholars have identified community colleges as ideal institutions to facilitate global justice through their involvement in internationalization activities such as study abroad. This chapter explores the meaning of humanism as it relates to study abroad at the community college. Using Andreotti, Stein, Pashby, and Nicolson's Paradigms of Discourse, the chapter describes the ways in which humanism can be defined in a variety of ways based on one's own goals. The chapter also grounds a rationale for study abroad at the community college within critical humanism by applying Young's Social Connections Model. Finally, the chapter applies the critical humanist rationale to begin to question the relationship between community college study abroad initiatives: Who is included in the community mission? Whose cultures come to be understood from involvement in study abroad? How are U. S. cultures represented by study abroad?

Abstract Lo u Is E E Ro RI c H ‘ s Love Medicine (1984)1 is most often classified as a novel. In fact, if we have any doubts about its genre, the title page informs us: “Love Medicine: A Novel by Louise Erdrich.” When asked what they thought about the fact that some reviewers of the “novel” insisted on labeling it a “collection of short stories,” Erdrich and her husband-collaborator Michael Dorris were not particularly interested in the topic. “It’s a novel in that it all moves toward some sort of resolution,” explained Erdrich. “It has a large vision that no one of the stories approaches,” added Dorris.2 In addition, even though half of the fourteen chapters of the first edition had been published previously as short stories in literary journals or popular magazines, Erdrich and Dorris insisted that they had adapted these individual stories significantly in order to create, extend, or enhance thematic, structural, and other literary connections.3 Erdrich, who describes herself as “a person who thought in terms of stories and poems and short-things,” credits Dorris’s influence for how the “book became a novel.”4 “By the time readers get half-way through the book,” noted Dorris, “it should be clear to them that this is not an unrelated, or even a related, set of short stories, but parts of a larger scheme” (Wong, 212). Length, an expansive vision, and some sense of unity seem to inform their notion of what constitutes a novel.

One dozen American Institute of Steel Construction (AISC) W14 steel columns were tested at the Energetic Materials Research and Testing Center (EMRTC), New Mexico Institute of Mining and Technology in Socorro, New Mexico with loading from typical size vehicle bomb threats at very close to moderately close standoffs. Pretest predictions of structural response were performed using standard SDOF methods and the Weidlinger Associates, Inc. (WAI) FLEX finite element code. Loads acting on the columns were determined from the U. S. Army developed CONWEP code using the Kingery-Bulmash equations for the pretest predictions. Seven tests included individual columns with axial loading and blast loading applied simulataneously. One test included 5 columns built into a frame with moment connections at the top of the columns and base plate connections at the base of the columns. The columns were instrumented with accelerometers and pressure transducers. The tests were designed to produce various levels of damage from mild to severe. This paper will compare the pretest and posttest predictions using both the SDOF and FLEX finite element methods with the actual test results. The comparison between actual loading and CONWEP loading will also be discussed. Conclusions will be drawn with regard to the use of CONWEP loading for this type of threat at various standoffs. Also, the use of SDOF and FLEX finite element methods to predict the response of AISC W14 steel columns will be compared.
