Reconsidering Severe or Pervasive: Aligning the Standard in Sexual Harassment and Racial Harassment Causes of Action
Reading intervention support for the older struggling reader : a desk-reference for reading interventions
Reading interventions for the older student are a topic of discussion in school districts, especially when an increasing number of middle schools and high schools are in need of improvement in the area of reading. Because of this increase in literacy concern in the middle and high schools, there is a need to better understand areas of reading that would assist struggling adolescent readers. Research affirms the importance of including intervention assistance in the upper grades. Research indicates key areas to target: structures and features of text, decoding, vocabulary, fluency, comprehension, writing and technology, as well as the incorporation of reading motivation

Stages of Blood: Transformations and Interpretations in Early Modern Drama
My thesis investigates the transformation of blood both as a physical substance and as a substance portrayed on the stage. During the 16th and early 17th Century, the scientific community moved further from considering blood as a substance of humoral significance and closer to understanding blood and its function in the scientific circulatory system. Examining drama written and performed between 1587 – 1606, I demonstrate that early modern drama also shifted its perception and performance of blood when attached to bodies and objects. Previously, literary scholars focus on blood’s singular connection with religion, gender, or the body politic in various early modern plays, or have investigated blood’s significance in particular places. In contrast, my study is concerned with the multi-faceted ways in which blood is signified and blood signifies varying character qualities and concerns. By also emphasizing the liminal space of the theatre, I reveal the ways in which the changing signification of blood in the theatrical space works in tandem with the scientific modifications happening outside it
Counting supersymmetric branes
Maximal supergravity solutions are revisited and classified, with particular
emphasis on objects of co-dimension at most two. This class of solutions
includes branes whose tension scales with g_s^{-\sigma} for \sigma>2. We
present a group theory derivation of the counting of these objects based on the
corresponding tensor hierarchies derived from E11 and discrete T- and U-duality
transformations. This provides a rationale for the wrapping rules that were
recently discussed for \sigma<4 in the literature and extends them. Explicit
supergravity solutions that give rise to co-dimension two branes are
constructed and analysed.Comment: 1+33 pages. To the memory of Laurent Houart. v2: Published version

Interaction of membrane-spanning proteins with peripheral and lipid-anchored membrane proteins: perspectives from protein- lipid interactions (Review)
Studies of lipid-protein interactions in double-reconstituted systems involving both integral and peripheral or lipid- anchored proteins are reviewed. Membranes of climyristoyl phosphatidylglycerol containing either myelin proteolipid protein or cytochrome c oxidase were studied. The partner peripheral proteins bound to these membranes were myelin basic protein or cytochrome c, respectively. In addition, the interactions between the myelin proteolipid protein and avidin that was membrane-anchored by binding to N-biotinyl phosphatidylethanolamine were studied in dimyristoyl phosphatidylcholine membranes. Steric exclusion plays a significant role when sizes of the peripheral protein and transmembrane domain of the integral protein are comparable. Even so, the effects on avidin-linked lipids are different from those induced by myelin basic protein on freely diffusible lipids, both interacting with the myelin proteolipid protein. Both the former and the cytochrome c/cytochrome oxidase couple evidence a propagation of lipid perturbation out from the intramembrane protein interface that could be a basis for formation of microdomains
A dynamical inconsistency of Horava gravity
The dynamical consistency of the non-projectable version of Horava gravity is
investigated by focusing on the asymptotically flat case. It is argued that for
generic solutions of the constraint equations the lapse must vanish
asymptotically. We then consider particular values of the coupling constants
for which the equations are tractable and in that case we prove that the lapse
must vanish everywhere -- and not only at infinity. Put differently, the
Hamiltonian constraints are generically all second-class. We then argue that
the same feature holds for generic values of the couplings, thus revealing a
physical inconsistency of the theory. In order to cure this pathology, one
might want to introduce further constraints but the resulting theory would then
lose much of the appeal of the original proposal by Horava. We also show that
there is no contradiction with the time reparametrization invariance of the
action, as this invariance is shown to be a so-called "trivial gauge symmetry"
in Horava gravity, hence with no associated first-class constraints.Comment: 28 pages, 2 references adde
On the full, strongly exceptional collections on toric varieties with Picard number three
We investigate full strongly exceptional collections on smooth, com- plete
toric varieties. We obtain explicit results for a large family of varieties
with Picard number three, containing many of the families already known. We
also describe the relations between the collections and the split of the push
forward of the trivial line bundle by the toric Frobenius morphism
K(E10), Supergravity and Fermions
We study the fermionic extension of the E10/K(E10) coset model and its
relation to eleven-dimensional supergravity. Finite-dimensional spinor
representations of the compact subgroup K(E10) of E(10,R) are studied and the
supergravity equations are rewritten using the resulting algebraic variables.
The canonical bosonic and fermionic constraints are also analysed in this way,
and the compatibility of supersymmetry with local K(E10) is investigated. We
find that all structures involving A9 levels 0,1 and 2 nicely agree with
expectations, and provide many non-trivial consistency checks of the existence
of a supersymmetric extension of the E10/K(E10) coset model, as well as a new
derivation of the `bosonic dictionary' between supergravity and coset
variables. However, there are also definite discrepancies in some terms
involving level 3, which suggest the need for an extension of the model to
infinite-dimensional faithful representations of the fermionic degrees of
freedom.Comment: 50 page
