Institutional pressures on financial services firms: the role of information systems in regulatory compliance

The financial crisis of 2008 led to new international regulatory controls for the governance, risk and compliance of financial services firms. Information systems play a critical role here as political, functional and social pressures may lead to the deinstitutionalization of existing structures, processes and practices. This research examines how an investment management system is introduced by a leading IT vendor across eight client sites in the post-crisis era. Using institutional theory, it examines changes in working practices occurring at the environmental and organizational levels and the ways in which technological interventions are used to apply disciplinary effects in order to prevent inappropriate behaviors. The results extend the constructs of deinstitutionalization and identify empirical predictors for the deinstitutionalization of compliance and trading practices within financial organizations.

Configurations institutionnelles de la protection de l’enfance: regards croisés de l’Afrique, de l’Europe et de l’Amérique du Nord

Cet article porte sur l’analyse de trois configurations institutionnelles de la protection de l’enfance : celle en place au Burkina Faso, en Belgique et au Québec. Pour chaque configuration, le texte explore les transformations qui ont marqué le passage de la prise en charge exclusive de l’enfant par la famille vers la présence accrue de l’État et la manière dont la Convention internationale des droits de l’enfant de 1989 a influencé ce passage. Il montre, au travers d’une lecture historique, que l’implication de l’État dans la protection des enfants a connu des formes et des modalités variables selon le temps et l’espace. L’approche actuelle en matière de protection de l’enfance au Nord et au Sud, approche largement inspirée de la perspective des droits, représente un défi tant pour les intervenants que pour les familles, car son application dépend à fois des ressources disponibles pour aider les enfants et les familles en difficulté, de la capacité d’action des institutions publiques et de l’efficacité des interventions. This article deals with the analysis of three institutional configurations of child protection: those in Burkina Faso, in Belgium, and in Québec. With respect to each configuration, the text explores the changes from situations in which the family had sole control of the child to those where the State played a greater role, and the manner in which the 1989 International Convention on the Rights of the Child has affected such changes. It shows, through a reading of history, that the involvement of the State in child protection has gone through different forms and stages over time and space. The current strategies as regards child protection in the North and in the South—an approach that is largely subject to a legal perspective—represent a challenge both for intervenors and for families, since their application depends on the resources available for helping children and families in difficulty, on the ability of the public institutions to intervene, and on the efficiency of such interventions.

A new pattern for historical geography: working with enthusiast communities and public history

This paper argues for the adoption of participatory approaches in historical geography, drawing on the author's experience in working with enthusiast communities in the UK in the context of collaborative research with the Science Museum and ideas of public history and geography.

Evaluation of film forming polymers to control apple scab (Venturia inaequalis (Cooke) G. Wint.) under laboratory and field conditions

A detached leaf bioassay was used to determine the influence of several film forming polymers and a conventional triazole fungicide on apple scab (Venturia inaequalis (Cooke) G. Wint.) development under laboratory in vitro conditions, supported by two field trials using established apple cv. Golden Delicious to further assess the efficacy of foliar applied film forming polymers as scab protectant compounds. All film forming polymers used in this investigation (Bond, Designer, Nu-Film P, Spray Gard, Moisturin, Companion PCT12) inhibited germination of conidia, subsequent formation of appressoria and reduced leaf scab severity using a detached leaf bioassay. Regardless of treatment, there were no obvious trends in the percentage of conidia with one to four appressoria 5 days after inoculation. The synthetic fungicide penconazole resulted in the greatest levels of germination inhibition, appressorium development and least leaf scab severity. Under field conditions, scab severity on leaves and fruit of apple cv. Golden Delicious treated with a film forming polymer (Bond, Spray Gard, Moisturin) was less than on untreated controls. However, greatest protection in both field trials was provided by the synthetic fungicide penconazole. Higher chlorophyll fluorescence Fv/Fm emissions in polymer and penconazole treated trees indicated less damage to the leaf photosynthetic system as a result of fungal invasion. In addition, higher SPAD values as measures of leaf chlorophyll content were recorded in polymer and penconazole treated trees. Application of a film forming polymer or penconazole resulted in a higher apple yield per tree at harvest in both the 2005 and 2006 field trials compared to untreated controls. Results suggest application of an appropriate film forming polymer may provide a useful addition to existing methods of apple scab management. (C) 2008 Elsevier Ltd. All rights reserved.

Antioxidant activity and protective effects of green and dark coffee components against human low density lipoprotein oxidation

The in vitro antioxidant activity and the protective effect against human low density lipoprotein oxidation of coffees prepared using different degrees of roasting was evaluated. Coffees with the highest amount of brown pigments (dark coffee) showed the highest peroxyl radical scavenging activity. These coffees also protected human low-density lipoprotein (LDL) against oxidation, although green coffee extracts showed more protection. In a different experiment, coffee extracts were incubated with human plasma prior to isolation of LDL particles. This showed, for the first time, that incubation of plasma with dark, but not green coffee extracts protected the LDL against oxidation by copper or by the thermolabile azo compound AAPH. Antioxidants in the dark coffee extracts must therefore have become associated with the LDL particles. Brown compounds, especially those derived from the Maillard reaction, are the compounds most likely to be responsible for this activity.

The impact of ICT on the work patterns of managers and their organisations

Purpose – The main aim of this paper is to present the results of a study examining managers' attitudes towards the deployment and use of information and communications technology (ICT) in their organisations. The study comes at a time when ICT is being recognised as a major enabler of innovation and new business models, which have the potential to have major impact on western economies and jobs. Design/methodology/approach – A questionnaire was specially designed to collect data relating to three research questions. The questionnaire also included a number of open-ended questions. A total of 181 managers from a wide range of industries across a number of countries participated in the electronic survey. The quantitative responses to the survey were analysed using SPSS. Exploratory factor analysis using Varimax rotation was used and ANOVA to compare responses by different groups. Findings – The survey showed that many of the respondents appeared equipped to work “any place, any time”. However, it also highlighted the challenges managers face in working in a connected operation. Also, the data suggested that many managers were less than confident about their companies' policies and practices in relation to information management. Originality/value – A next step from this exploratory research could be the development of a model exploring the impact of ICT on management and organisational performance in terms of personal characteristics of the manager, the role performed, the context and the ICT provision. Also, further research could focus on examining in more detail differences between management levels.

Carbon monoxide protects against oxidant-induced apoptosis via inhibition of Kv2.1

Oxidative stress induces neuronal apoptosis and is implicated in cerebral ischemia, head trauma, and age-related neurodegenerative diseases. An early step in this process is the loss of intracellular K(+) via K(+) channels, and evidence indicates that K(v)2.1 is of particular importance in this regard, being rapidly inserted into the plasma membrane in response to apoptotic stimuli. An additional feature of neuronal oxidative stress is the up-regulation of the inducible enzyme heme oxygenase-1 (HO-1), which catabolizes heme to generate biliverdin, Fe(2+), and carbon monoxide (CO). CO provides neuronal protection against stresses such as stroke and excitotoxicity, although the underlying mechanisms are not yet elucidated. Here, we demonstrate that CO reversibly inhibits K(v)2.1. Channel inhibition by CO involves reactive oxygen species and protein kinase G activity. Overexpression of K(v)2.1 in HEK293 cells increases their vulnerability to oxidant-induced apoptosis, and this is reversed by CO. In hippocampal neurons, CO selectively inhibits K(v)2.1, reverses the dramatic oxidant-induced increase in K(+) current density, and provides marked protection against oxidant-induced apoptosis. Our results provide a novel mechanism to account for the neuroprotective effects of CO against oxidative apoptosis, which has potential for therapeutic exploitation to provide neuronal protection in situations of oxidative stress.

Flight of Meligethes aeneus at a range of altitudes

The pollen beetle, Meligethes aeneus, is a significant pest of oilseed rape crops and there is considerable research effort focused on developing novel, sustainable methods of integrated control. These insects rely on flight for all dispersal movements and we have investigated their flight patterns using a novel combination of data from suction traps, vertical-looking radar and field counts. Analysis of these preliminary data will help determine the best timing for different control measures within an integrated pest management strategy.

Travail des enfants et droit à l’éducation au Burkina Faso: L’exemple de la carrière de Pissy

Cet article décrit et analyse le travail des enfants dans une carrière de granit d’un quartier de la ville de Ouagadougou, interroge le rapport entre l’école et le travail du point de vue des acteurs du site pour apprécier l’argument de la scolarisation comme solution alternative au travail des enfants. Les données proviennent d’une enquête réalisée dans le cadre de notre recherche doctorale au Burkina Faso, de février à avril 2009, dont la carrière de Pissy a été un des terrains d’enquête1. Les enquêtés sont constitués de parents et de leurs enfants âgés de moins de 16 ans ayant des trajectoires différentes : non scolarisés,scolarisés, déscolarisés et à la fois écoliers et travailleurs. Les personnes ont été choisies aléatoirement selon leur accord et disponibilité, en variant leur emplacement. L’approche choisie privilégie le point de vue des différents acteurs du site,l’analyse de leurs discours et l’observation de leurs pratiques de travail. La prise en compte du point de vue des enfants s’appuie sur la perspective théorique développée par James & Prout (1997), où les enfants sont des acteurs compétents dans la sphère du travail et de la vie sociale. L’article présente d’abord le processus d’institutionnalisation de l’école et la situation du travail des enfants au Burkina Faso, puis décrit les logiques autour du travail des enfants dans la carrière en montrant que celui-ci n’est pas seulement lié à la nécessité économique. Enfin, il confronte les alternatives au travaildes enfants invoquées par les enfants et leurs parents aux solutions d’éducation proposées par l’état et la société civile. This article is about a particular case of children in working situation: children crushing the granite in the quarry of Pissy. Their working conditions are considered as dangerous by national and international legal texts. This article aims to grasp the experience of children who work in this frame in order to test the hypothesis according to which schooling would be an effective tool of struggle against child labour. The fieldwork reveals that child labour in the quarry is not only guided by economic aspects. The wish of the parents (and of some children and teenagers) to find another job for working children reopen the debate on “the right to work” for children.
