The Roles We Played: Exploring Intimacy in Research
Intimate relationships can serve as catalysts impelling us to deeply interact with others, and, consequently helping us to develop a greater understanding of ourselves, those with whom we come into contact, and the wider world. This manuscript describes the challenges and constraints I faced when engaged in qualitative research with an intimate other. I borrow from Dr. Carolyn Ellis’ (2007) concept of relational ethics, which requires researchers to: (a) act from their hearts and minds, (b) acknowledge interpersonal bonds to others, and (c) take responsibility for actions and their consequences. Power is a part of intimate relationships, so exploring and discussing power issues is critical in developing a solid research design and research processes when we involve intimate others, not to mention a solid baseline for a familial relationship. In this manuscript, I share methods I developed to interrogate my own awareness of my situated power/authority
MIDDLEMARCH : Three Italian Journeys
In Middlemarch, Dorothea’s intense moment of disillusionment in Rome has been generally traced to Eliot’s own Italian journey of 1860, when, as Gordon S. Haight notes (324),1 the disappointment in many sights of the Eternal City paralleled her heroine’s. The comparisons are very compelling, especially those involving the joined responses of author and heroine to the interior landscape of St. Paul’s (“the lovely marble… was half-covered with hideous red drapery (Life 132: vol. 2, ch. 10);2 the red drapery which was being hung for Christmas spreading itself everywhere (was) like a disease of the retina (226; ch. 20)).3 However, the famous and almost surreal paragraph which shows, with such extraordinary power, the dimmer but yet eager Titanic life gazing and struggling on walls and ceilings (226)3 may, in fact, carry another, less direct reference
Methyl 2-(4-ferrocenylbenzamido)thiophene-3-carboxylate and ethyl 2-(4-ferrocenylbenzamido)-1,3-thiazole-4-acetate, a unique ferrocen
The conformations and hydrogen bonding in the thiophene and thiazole title compounds, [Fe(C₅H₅)(C₂₀H₁₄NO₃S)], (I), and [Fe(C₅H₅)(C₁₉H₁₇N₂O₃S)], (II), are discussed. The sequence (C₅H₄)-(C₆H₄)-(CONH)-(C₄H₂S)-(CO₂Me) of rings and moieties in (I) is close to being planar; all consecutive interplanar angles are less than 10°. An intramolecular N-H...O=Cester hydrogen bond [graph set S(6), N...O = 2.768 (2) Å and N-H...O = 134 (2)°] effects the molecular planarity, and aggregation occurs via hydrogen-bonded chains formed from intermolecular Car-H...O=Cester/amide interactions along [010], with C...O distances ranging from 3.401 (3) to 3.577 (2) Å. The thiazole system in (II) crystallizes with two molecules in the asymmetric unit; these differ in the conformation along their long molecular axes; for example, the interplanar angle between the phenylene (C₆H₄) and thiazole (C₃NS) rings is 8.1 (2)° in one molecule and 27.66 (14)° in the other. Intermolecular N-H...O=Cester hydrogen bonds [N...O = 2.972 (4) and 2.971 (3) Å], each augmented by a Cphenylene-H...O=Cester interaction [3.184 (5) and 3.395 (4) Å], form motifs with graph set R¹₂(7) and generate chains along [100]. The amide C=O groups do not participate in hydrogen bonding. Compound (II) is the first reported ferrocenyl-containing thiazole structure
Synthesis and characterisation of novel ferrocenyl thienyl and thiazolyl systems
Ferrocenyl derivatives are currently under investigation by our group and several series containing both amidothienyl and amidothiazolyl systems have been synthesised and characterised. The incorporation of thienyl/thiazolyl groups into a ferrocenyl- or ferrocenylphenyl system greatly enhances the number of potential donor atoms for coordination with metal fragments e.g. PtII, PdII with a view to platinum anti-cancer studies and/or interaction with guest molecules through suitable hydrogen bonding interactions.
In nature, thiazole has been found to be vital in certain natural products: examples include the antibiotic bacitracin and the siderophore yersiniabactin. In therapeutic studies the antitumour compound epothilone A and myxothiazole (inhibitor) have been extensively studied
The far field diffraction pattern for corner reflectors with complex reflection coefficients
The far field diffraction pattern of a geometrically perfect corner reflector is examined analytically for normally incident monochromatic light. The states of polarization and the complex amplitudes of the emerging light are expressed through transformation matrices in terms of those of the original incident light for each sextant of the face in a single coordinate system. The analytic expression of the total diffraction pattern is obtained for a circular face. This expression consists of three component functions in addition to the basic Airy function. The coefficient of each function is expressed in terms of complex coefficients of reflectance of the reflecting surface. Some numerical results for different reflecting surfaces, including total internal reflection, are presented. The iso-intensity contours of the diffraction pattern evaluated from the analytical expressions for an uncoated solid corner reflector are also presented along with the photographs of the pattern
The Effect of Teaching Sixth Graders with Learning Difficulties a Strategy for Solving Verbal Math Problems
This research was published by the KU Center for Research on Learning, formerly known as the University of Kansas Institute for Research in Learning Disabilities.In this study, subjects were taught a seven-step verbal problem-solving strategy. Results indicated an increase in percent correct on eight mathematics word problems for each subject following intervention. Baseline probes never overlapped with treatment probes indicating that generalization is possible to other students in the population studied
