Student expectations and perceptions of feedback in Chemistry

These documents show the outcomes of surveys conducted by David Read in the School of Chemistry to find out about our students' expectations and perceptions of feedback, with a view to enhancing our provision and ensuring that student learning is maximised.

Complementación del diseño de un sistema de información para la toma de decisiones caso FNA

La solución a las necesidades de vivienda de los colombianos, ha ocupado espacios importantes en las políticas públicas de diferentes gobiernos a lo largo del tiempo. Para ello, se han implementado diversas estrategias, que han ido desde la creación de entidades responsables de la administración de proyectos habitacionales, pasando por la incorporación de entidades oficiales y privadas que se vinculan a través de la otorgación de créditos, estimulo a la construcción de diferentes soluciones habitacionales y llegando al diseño de medidas financieras que buscan el estimulo al desembolso de créditos exequibles a través instituciones financieras. El FNA, desempeña un papel trascendental en la solución a las necesidades de los colombianos en su aspiración a tener vivienda propia, ahí se ha entendido que la vivienda usada también hace parte de la solución, para ello, se busca integrar dentro de los estudios de financiamiento del crédito, este proyecto, con el fin de que enlace vendedores y compradores, clasificados por rangos de precio de inmuebles y montos de crédito aprobado, con el fin de optimizar la labor del FNA y disminuir los casos de devolución del crédito por parte del beneficiario, a causa de ausencia de opciones de vivienda que se ajusten a su presupuesto. Así mismo dentro del marco de la Responsabilidad Social Empresarial y para dar respuesta a las expectativas de uno de los Grupos de Interés prioritario del FNA, en concordancia con una de las siete materias fundamentales que consagra la Norma ISO 26.000, denominada “Asunto de los Consumidores”, es un valor agregado a las funciones y servicios brindados por el FNA a sus afiliados para facilitarles la adquisición de su vivienda.

The False Expectations of Michael Porter's Strategic Management Framework

El artículo busca demostrar las inconsistencias del pensamiento estratégico de Porter desde el punto de vista metodológico y epistemológico. De igual manera, muestra que las propuestas praxológicas de Porter son imposibles de operacionalizar y normativizar. Además, la teoría carece de factores fundamentales que permitan a las organizaciones perdurar y ser exitosas en el tiempo teniendo ventaja defendible y difícilmente imitable.

Does uncertainty cause inertia in decision making? An experimental study of the role of regret aversion and indecisiveness

Previous research has shown that often there is clear inertia in individual decision making---that is, a tendency for decision makers to choose a status quo option. I conduct a laboratory experiment to investigate two potential determinants of inertia in uncertain environments: (i) regret aversion and (ii) ambiguity-driven indecisiveness. I use a between-subjects design with varying conditions to identify the effects of these two mechanisms on choice behavior. In each condition, participants choose between two simple real gambles, one of which is the status quo option. I find that inertia is quite large and that both mechanisms are equally important.

The representation of conditional expectations of non-Gaussian noise

For Wiener spaces conditional expectations and $L^{2}$-martingales w.r.t. the natural filtration have a natural representation in terms of chaos expansion. In this note an extension to larger classes of processes is discussed. In particular, it is pointed out that orthogonality of the chaos expansion is not required.

Rational modification of the hierarchy of intermolecular interactions in molecular crystal structures by using tunable halogen bonds

A family of 16 isomolecular salts (3-XpyH)(2)[MX'(4)] (3-XpyH=3-halopyridinium; M=Co, Zn; X=(F), Cl, Br, (I); X'=Cl, Br, I) each containing rigid organic cations and tetrahedral halometallate anions has been prepared and characterized by X-ray single crystal and/or powder diffraction. Their crystal structures reflect the competition and cooperation between non-covalent interactions: N-H center dot center dot center dot X'-M hydrogen bonds, C-X center dot center dot center dot X'-M halogen bonds and pi-pi stacking. The latter are essentially unchanged in strength across the series, but both halogen bonds and hydrogen bonds are modified in strength upon changing the halogens involved. Changing the organic halogen (X) from F to I strengthens the C-X center dot center dot center dot X'-M halogen bonds, whereas an analogous change of the inorganic halogen (X') weakens both halogen bonds and N-H center dot center dot center dot X'-M hydrogen bonds. By so tuning the strength of the putative halogen bonds from repulsive to weak to moderately strong attractive interactions, the hierarchy of the interactions has been modified rationally leading to systematic changes in crystal packing. Three classes of crystal structure are obtained. In type A (C-F center dot center dot center dot X'-M) halogen bonds are absent. The structure is directed by N-H center dot center dot center dot X'-M hydrogen bonds and pi-stacking interactions. In type B structures, involving small organic halogens (X) and large inorganic halogens (X'), long (weak) C-X center dot center dot center dot X'-M interactions are observed with type I halogen-halogen interaction geometries (C-X center dot center dot center dot X' approximate to X center dot center dot center dot X'-M approximate to 155 degrees), but hydrogen bonds still dominate. Thus, minor but quite significant perturbations from the type A structure arise. In type C, involving larger organic halogens (X) and smaller inorganic halogens (X'), stronger halogen bonds are formed with a type II halogen-halogen interaction geometry (C-X center dot center dot center dot X' approximate to 180 degrees; X center dot center dot center dot X'-M approximate to 110 degrees) that is electrostatically attractive. The halogen bonds play a major role alongside hydrogen bonds in directing the type C structures, which as a result are quite different from type A and B.

Supply, demand and a failure of understanding: addressing the culture clash between archaeologists' expectations for training and employment in 'academia' versus 'practice

A university degree is effectively a prerequisite for entering the archaeological workforce in the UK. Archaeological employers consider that new entrants to the profession are insufficiently skilled, and hold university training to blame. But university archaeology departments do not consider it their responsibility to deliver fully formed archaeological professionals, but rather to provide an education that can then be applied in different workplaces, within and outside archaeology. The number of individuals studying archaeology at university exceeds the total number working in professional practice, with many more new graduates emerging than archaeological jobs advertised annually. Over-supply of practitioners is also a contributing factor to low pay in archaeology. Steps are being made to provide opportunities for vocational training, both within and outside the university system, but archaeological training and education within the universities and subsequently the archaeological labour market may be adversely impacted upon by the introduction of variable top-up student fees.
