A-level chemistry content

This document outlines the material covered by the main UK exam board specifications at A-level in chemistry. This is for the A-level taught up until and including June 2009 (i.e. relevant to undergraduates arriving at university in October 2009).

Review of A-level Chemistry content 2010

This document is a review of the content of the A-level Chemistry specifications from the main UK exam boards (Scottish highers not included - sorry!). These A-level specifications commenced teaching in September 2008. Students entering university in 2010 will have studied the new A-levels, and this document is intended to help academics to identify what students will have covered. The document also contains a summary of discussions which took place between teachers and academics at our annual Post-16 teachers' day in June 2010 regarding the nature of the 2010 intake and their capabilities in chemistry. Please inform us of any errors or typos that you spot and we'll update the document. LAST UPDATE at 13:15 on Aug 27th 2010.

Powerpoint to promote chemistry to A-level students

This presentation has been modified by a B.Sc final year project student to promote chemistry as a degree and a career option for youngsters. The original presentation was produced by the Biological and Medicinal Chemistry Sector or the Royal Society of Chemistry. The project student has polished the slides to make them more appealing to today's A-level students. She has also evaluated the impact of her work. A summary of her report will be added in due course.

Review of A-level Chemistry content 2015

ITEM DESCRIPTION After producing reviews of A-level Chemistry content in 2007 and 2010, we have updated the document to reflect the changes which have been introduced for first teaching in September 2015. We will be working with our network of teachers locally to monitor the impacts of the changes on teaching and the student experience with a view to releasing an updated version in the summer of 2017. This will aim to provide insights for university staff regarding the experiences of incoming students who will have been in the first cohort to have studied the new specifications. We are grateful to the Royal Society of Chemistry for support for the final stages of compiling this report. If you spot any errors or omissions, please don't hesitate to contact us.

Incidencia del cambio climático en la seguridad ambiental de las maldivas. Un desafío para la construcción de un régimen internacional de refugiados ambientales (2000-2012)

El interés de esta investigación diagnóstica es evaluar el tema de los refugiados ambientales en las legislaciones internacionales que se encuentran en vigencia actualmente. Es un elemento de análisis pertinente debido a que durante los últimos años el cambio climático y sus efectos adversos han causado estragos en algunas poblaciones, dando origen a lo que se conoce como refugiados ambientales. Así, la falta de inclusión del concepto en la normatividad internacional, representa una problemática, en tanto que estas personas no tienen ningún tipo de apoyo por parte de la Comunidad Internacional. En este trabajo se centra en el caso de las Islas Maldivas y refleja la necesidad de crear un nuevo régimen internacional que cubra a la figura de refugiados ambientales, para así hacer frente a esta problemática internacional.

Citizen safety at local level: fieldwork notes on performance and perception of the ‘Quadrant Plan’ in Cali (Colombia)

This article summarizes field notes related to the study of the actions performed by the Metropolitan Police of Santiago de Cali in the context of its ‘Plan Cuadrante’ (a micro-local security action plan) and the citizen’s perception towards it. Taking an ethnographic approach, it places special emphasis on the actions that imply identifying the main criminal and violent actors and activities. The study focuses on four local districts of the city: El Cortijo, Mariano Ramos, Terrón Colorado y Villa del Lago.

Frequency of Low-level Mosaicism in X-Cromosome in Couples with Antecedent of Recurrent Miscarriages

Recurrent miscarriage occurs in around 1 to 7 percent of couples. The etiology involves genetic, immunologic, anatomic, hormonal, metabolic, thrombophilic and infectious factors. With the aim of establishing the frequency of low-level mosaicism in the X-chromosome, in a population of couples with prior recurrent miscarriages, a prospective case-control cytogenetic study took place on 20 couples, at the biogenetic laboratory in CECOLFES (Colombian Center of Fertility and Sterility). Clinical pathologic evaluation, anatomic, hormonal, infectious, andrologic and genetic studies were performed. As a conventional method in cytogenetic techniques, banding GTG was used for the study of structural and numeric chromosomal abnormalities whereas the molecular method of Fluorescence In Situ Hybridization (FISH) was used to confirm the mosaicism in sexual chromosomes. According to paraclinic results from the participating couples, diagnosis showed immunologic (75%), anatomic (30%), hormonal (25%), male (25%), infectious (25%), genetic (15%) and idiophatic factors (10%). Results from the cytogenetic analysis, were 10% of low-level mosaicism in the X-chromosome in two women whose final diagnosis included genetic and infectious factors for one and genetic and immunologic factors for the other. Only 10 % of the total miscarriages from the couples were evaluated. Conclusions include aspects such as multifactorial evidence of pathogenesis in recurrent miscarriage, the sub-diagnosis of genetic factors and the need to focus future investigations on cytogenetic interpretation and the clinicalpathological association between low-level mosaicism in the X-cromosome and recurrent miscarriage.

Estudio de caso. “el papel de los refugiados en la implementación de la política de libre circulación de la cedeao: visto desde el flujo de Liberia a Ghana”

Este estudio de caso tiene como objetivo determinar las implicaciones del flujo de población refugiada en la implementación de la política de libre circulación de la CEDEAO; tomando como referente el flujo desde Liberia hacia Ghana generado por la Guerra Civil. Esta investigación defiende que las implicaciones pueden estar relacionadas a las dinámicas que se asocian al movimiento de personas, las cuales pueden ser negativas o positivas, razón por la cual los Estados pueden reaccionar endureciendo las políticas migratorias, la obtención de permisos laborales y de residencia, y el cierre de fronteras o la expulsión de refugiados; con el fin de evitar consecuencias a nivel político, económico o en materia de seguridad. Para comprobar lo anterior se va a realizará un análisis de texto, sobre posiciones nacionales y políticas comunitarias, así como una revisión de estudios y estadísticas relacionados con el tema.

Land Reform, Latifundia and Social Development at Local Level in Colombia, 1961-2010

The paper analyzes the effects of land reform on social development – poverty and land distribution-at the local level. Land reform in Colombia, understood as the allocation of public land to peasant, has granted 23 million hectares which comprises around 20% of Colombian territory and about 50% of usable productive land. Theoretically, the net impact of land reform on development is the combination of a poverty effect and a land distribution effect. Our findings suggest that land reform from 1961 onwards has slightly reduced poverty and mildly improved land distribution. Nonetheless,municipalities with strong presence of latifundia prior to1961 have experienced both a slower drop in poverty and a weaker improvement of land distribution .This paper finds that prevalence of latifundia partially offset the positive effect of land reform in promoting social development.
