The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend
The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend
Joseph W. Houpt
The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a model of mental processes. Despite its demonstrated utility, the methodology has lacked a method for statistical testing until now. In this paper we briefly describe the SIC then develop some basic statistical properties of the measure. These developments lead to a statistical test for rejecting certain classes of models based on the SIC. We verify these tests using simulated data, then demonstrate their use on data from a simple cognitive task.

Floristic Investigation Of Crooked Creek Community Of Juan Solomon Park, Indianapolis Indiana, Raelene M. Crandall, Rebecca W. Dolan
Rebecca W. Dolan
The protection of plant resources in urban areas is a growing conservation concern. Inventory activities that document species presence and stewardship plans that protect and enhance these areas are needed. The results of a botanical inventory of the Crooked Creek Community Juan Solomon Park in Indianapolis, Indiana, are reported in this paper. The 46-acre park contains three distinct habitats, supporting a wide variety of plants. One hundred seventy-nine vascular plant species from 64 families were identified, including 53 (29.6%) non-native species that are naturalizing within the park. Despite its high percentage of alien species and urban setting, the park is …
Research Data: Who Will Share What, With Whom, When, And Why?, Christine L. Borgman
Research Data: Who Will Share What, With Whom, When, And Why?, Christine L. Borgman
Christine L. Borgman
The deluge of scientific research data has excited the general public, as well as the scientific community, with the possibilities for better understanding of scientific problems, from climate to culture. For data to be available, researchers must be willing and able to share them. The policies of governments, funding agencies, journals, and university tenure and promotion committees also influence how, when, and whether research data are shared. Data are complex objects. Their purposes and the methods by which they are produced vary widely across scientific fields, as do the criteria for sharing them. To address these challenges, it is necessary …

History Of Communication And Its Application In Multicultaral,Multilingual Social System In India Across Ages, Ratnesh Dwivedi Mr
Ratnesh Dwivedi
The history of communication dates back to the earliest signs of cavemen.Communication can range from very subtle processes of exchange, to full conversations and mass communication. Human communication was revolutionized with speech perhaps 200,000 years ago, Symbols were developed about 30,000 years ago and writing about 7,000. On a much shorter scale, there have been major developments in the field of telecommunication in the past few centuries.

Anyone associated with higher education will acknowledge that tenure track faculty have to perform a fantastic balancing act. Compared to an administrative or line role in an organization, higher education faculty have tremendous autonomy and freedom. However, they face competing demands of many different (and good) opportunities, and for them the stakes are always high. Help is here! This article introduces a powerful strategy for staying on track in the research strand of this competitive journey.

Synthesis And In Vitro Binding Of N,N-Dialkyl-2-Phenylindol-3-Ylglyoxylamides For The Peripheral Benzodiazepine Binding Sites, T. P. Homes, F. Mattner, Paul A. Keller, A. Katsifis
Paul Keller
A series of N,N-dialkyl-2-phenylindol-3-ylglyoxylamides bearing the halogens iodine and bromine were synthesised and their binding affinity for the peripheral benzodiazepine binding sites (PBBS) in rat kidney mitochondrial membranes were evaluated using [3H]-PK11195. Central benzodiazepine receptor (CBR) affinities were also evaluated in rat cortices using 3H-flumazenil to determine their selectivity for PBBS over CBR. The tested compounds had PBBS binding affinities (IC50) ranging from 7.86 nM to 618 nM, with all compounds showing high selectivity over the CBR (CBR IC50 > 5000 nM). Among the 12 compounds tested, those with a diethylamide group were the most potent. The highest affinity iodinated PBBS …
Synthesis Of Some Cyclic Indolic Peptoids As Potential Antibacterials, Vicki S. Au, John B. Bremner, Jonathan Coates, Paul A. Keller, Stephen G. Pyne
Synthesis Of Some Cyclic Indolic Peptoids As Potential Antibacterials, Vicki S. Au, John B. Bremner, Jonathan Coates, Paul A. Keller, Stephen G. Pyne
Paul Keller
The synthesis of cyclic peptoids containing an indole hydrophobic scaffold has been realised through the ring-closing metathesis of diallylated precursors. The precursors and their cyclic counterparts possessed poor antibacterial activity in contrast to previously reported cyclic peptoids containing hydrophobic scaffolds.

Reactions Of Iminoglycines With C60 Fullerene And Their Unambiguous Characterisation Using Nmr Spectroscopy, Paul A. Keller, Stephen G. Pyne, Bill C. Hawkins
Reactions Of Iminoglycines With C60 Fullerene And Their Unambiguous Characterisation Using Nmr Spectroscopy, Paul A. Keller, Stephen G. Pyne, Bill C. Hawkins
Paul Keller
This review examines the addition of iminoglycine derivatives to C60, yielding protected fullerenyl pyrroline derivatives. Subsequent reduction with sodium cyanoborohydride produces ring-opening adducts which are protected fullerenyl α-amino acids. Pyrroline bisadducts can be produced using tethers to link two iminoglycine units together, and variations include combining with malonate reactive groups this giving rise to interesting observations as to the regioselectivity of such reactions. All derivatives are fully characterised by NMR spectroscopy, and in the case of bis-adducts, the regioselectivity is determined from 1H/13C and 13C/13C connectivity patterns using HMBC and INADEQUATE experiments, respectively, thus eliminating the need for comparative techniques …
New Cyclic Peptides Via Ring-Closing Metathesis Reactions And Their Anti-Bacterial Activities, Timothy P. Boyle, John B. Bremner, Jonathan Coates, John Deadman, Paul A. Keller, Stephen G. Pyne, David I. Rhodes
New Cyclic Peptides Via Ring-Closing Metathesis Reactions And Their Anti-Bacterial Activities, Timothy P. Boyle, John B. Bremner, Jonathan Coates, John Deadman, Paul A. Keller, Stephen G. Pyne, David I. Rhodes
Paul Keller
As part of a program investigating cyclic peptides with an internal aromatic hydrophobic scaffold as potential novel anti-bacterial agents, we explored the synthesis of simple tyrosine-based systems. These were prepared via key intermediates containing internal allylglycine and allyltyrosine residues for subsequent ring closing metathesis reactions. Although the resulting anti-bacterial activity against Staphylococcus aureus was modest, this represents a novel and simple route to this class of compounds. One intermediate acyclic dipeptide precursor showed good activity against S. aureus with an MIC of 7.8 µg/mL.
Regioselective Synthesis Of Novel E-Edge-[60]Fullerenylmethanodihydropyrroles And 1,2-Dihydromethano[60]Fullerenes, Leila Chaker, Graham E. Ball, James R. Williams, Glenn A. Burley, Bill C. Hawkins, Paul A. Keller, Stephen G. Pyne
Regioselective Synthesis Of Novel E-Edge-[60]Fullerenylmethanodihydropyrroles And 1,2-Dihydromethano[60]Fullerenes, Leila Chaker, Graham E. Ball, James R. Williams, Glenn A. Burley, Bill C. Hawkins, Paul A. Keller, Stephen G. Pyne
Paul Keller
Treatment of a tethered N-(diphenylmethylene)glycinate-malonate derivative with [60]fullerene under Bingel conditions yielded an e-edge-[60]fullerenylmethanodihydropyrrole adduct in a regioselective manner. The regiochemical outcome was independent of the order of addition of either the N-(diphenylmethylene)glycinate or the malonate moieties. This new bis-adduct was also prepared in 13C enriched form allowing for its unequivocal structural characterization by 2D INADEQUATE NMR experiments. Ring-opening of the dihydropyrrole functionality of the bisadducts under reductive conditions gave exclusively novel dihydromethano[60]fullerene derivatives.
The Role Of The Hpa Axis In Psychiatric Disorders And Crf Antagonists As Potential Treatments, Paul A. Keller, A. Mccluskey, J. Morgan, S. M. O'Connor
The Role Of The Hpa Axis In Psychiatric Disorders And Crf Antagonists As Potential Treatments, Paul A. Keller, A. Mccluskey, J. Morgan, S. M. O'Connor
Paul Keller
An overview of the links between the Hypothalamic-Pituitary-Adrenal (HPA) axis and psychiatric disorders is presented. The current treatments are outlined, indicating that they are insufficient to meet the needs of those that suffer from these affective disorders. Therefore, there is an urgent need for the generation of new therapeutics, in particular, against new targets. The association of the corticotrophin releasing factor (CRF) and the HPA axis indicates that CRF antagonists should be beneficial as potential therapeutics.

Aryl Nitro Reduction With Iron Powder Or Stannous Chloride Under Ultrasonic Irradiation, A. B. Gamble, James A. Garner, Christopher Gordon, S. M. J. O'Conner, Paul A. Keller
Aryl Nitro Reduction With Iron Powder Or Stannous Chloride Under Ultrasonic Irradiation, A. B. Gamble, James A. Garner, Christopher Gordon, S. M. J. O'Conner, Paul A. Keller
Paul Keller
The selective reduction of aryl nitro compounds in the presence of sensitive functionalities, including halide, carbonyl, nitrile and ester substituents under ultrasonic irradiation at 35 kHz is reported in yields of 39-98%. Iron powder proved superior to stannous chloride with high tolerance of sensitive functional groups and high yields of the desired aryl amines in relatively short reaction times. Simple experimental procedure and purification also make the iron reduction of aryl nitro compounds advantageous over other methods of reduction.
Control Of Hiv Through The Inhibition Of Hiv-1 Integrase: A Medicinal Chemistry Perspective, Christopher Gordon, R. Griffith, Paul A. Keller
Control Of Hiv Through The Inhibition Of Hiv-1 Integrase: A Medicinal Chemistry Perspective, Christopher Gordon, R. Griffith, Paul A. Keller
Paul Keller
This article reviews the current status of classes of HIV-1 integrase enzyme inhibitors. These classes include peptide-based inhibitors, natural products, polyhydroxylated aromatics, diketo acids, naphthyridines, and sulfonated compounds including sulfonic acids. Discussions of structure activity relationships are presented and include the current overview of the structure-based model, suitable for the further design and development. To date, the advances in the medicinal chemistry of HIV-1 integrase inhibitors have relied mostly on ligand-based designs leading to most displaying similar binding interactions within the active site or at the dimer interface. This paves the way for single enzyme mutations rendering entire compound classes …

The role of the corticotropin releasing hormone in the onset of labour and the subsequent medicinal chemistry implications of CRH antagonists for the prevention of premature birth, and identification of the CRH type 1 receptor as the target for this drug design, are reviewed here.
A New Methodology For The Simulation Of Flexible Protein – Ligand Interactions, James A. Garner, John Deadman, David I. Rhodes, Renate Griffith, Paul A. Keller
A New Methodology For The Simulation Of Flexible Protein – Ligand Interactions, James A. Garner, John Deadman, David I. Rhodes, Renate Griffith, Paul A. Keller
Paul Keller
A methodology has been developed for the simulation of induced fit between a ligand and its target protein. It utilizes constrained molecular dynamics where atoms determined to be immobile from difference distance matrix studies are fixed. Application of this methodology to HIV-1 reverse transcriptase (RT) as the example target protein has demonstrated its robustness. Short simulation times are sufficient to achieve good refinement of docking poses resulting from exchange of structurally dissimilar inhibitors between crystal structures.

Corticotropin Releasing Hormone - A Gpcr Drug Target, C. Hemley, A. Mccluskey, Paul A. Keller
Paul Keller
Corticotrophin Releasing Hormone (CRH) is a primary hormone in the fight or flight response targeting a membrane bound G-protein coupled receptor (GPCR). Many people worldwide stand to benefit by the development of CRH agonists and antagonists for the treatment of anxiety and depression, with additional therapeutic targets including Alzheimer’s, pain and the prevention of premature birth: so why the delay in development? In this review, we will discuss not only CRH, related proteins, receptors and ligands, but some of the obstacles that have arisen, as well as strategies being pursued to overcome these problems in the pursuit of this GPCR …
Combining Structure-Based Drug Design And Pharmacophores, Renate Griffith, T. T. T. Luu, James A. Garner, Paul A. Keller
Combining Structure-Based Drug Design And Pharmacophores, Renate Griffith, T. T. T. Luu, James A. Garner, Paul A. Keller
Paul Keller
Development towards integrated computer-aided drug design methodologies is presented by utilising crystal structure complexes to produce structure-based pharmacophores. These novel pharmacophores represent the ligand features that are involved in interactions with the target protein, as well as the space around the ligand occupied by the protein. The protein-ligand complexes can also yield information about all interactions that ligands could potentially form with the binding site, as well as about the size of the binding cavity. Together, these describe a 'superligand', which can also be viewed as a pharmacophore. Various types of novel pharmacophores are discussed and compared, using HIV-1 Reverse …

Functional Principal Components Analysis And The Capacity Coefficient, D. Burns, Joseph W. Houpt, M. J. Endres, J. T. Townsend
Joseph W. Houpt
The capacity coefficient is a well established measure of the efficiency of processing combined sources of information. It has been applied to measure cognitive processes ranging from audio-visual integration to face perception. Recently, the capacity coefficient has also been applied in various clinical situations. Typical clinical analysis, such as structural equation modeling, use scalar values or vectors with limited length as input. We explored the use of functional principal component analysis (fPCA) to allow researchers to describe the capacity coefficient, a continuous function of time, with a small set of discrete values. The fPCA approach was compared with two simple …
Estimating Confidence Intervals For Eigenvalues In Exploratory Factor Analysis, Ross Larsen, Russell Warne
Estimating Confidence Intervals For Eigenvalues In Exploratory Factor Analysis, Ross Larsen, Russell Warne
Russell T Warne
Exploratory factor analysis (EFA) has become a common procedure in educational and psychological research. In the course of performing an EFA, researchers often base the decision of how many factors to retain on the eigenvalues for the factors. However, many researchers do not realize that eigenvalues, like all sample statistics, are subject to sampling error, which means that confidence intervals (CIs) can be estimated for each eigenvalue. In the present article, we demonstrate two methods of estimating CIs for eigenvalues: one based on the mathematical properties of the central limit theorem, and the other based on bootstrapping. References to appropriate …

Multirelational Organization Of Large-Scale Social Networks In An Online World, Renaud Lambiotte
Renaud Lambiotte
The capacity to collect fingerprints of individuals in online media has revolutionized the way researchers explore human society. Social systems can be seen as a nonlinear superposition of a multitude of complex social networks, where nodes represent individuals and links capture a variety of different social relations. Much emphasis has been put on the network topology of social interactions, however, the multidimensional nature of these interactions has largely been ignored, mostly because of lack of data. Here, for the first time, we analyze a complete, multirelational, large social network of a society consisting of the 300,000 odd players of a …
