Support in decision-making under uncertainty: a project risk assessment tool development and supplementary advances

A foremost dispute that persists on the contemporary world’s agenda is change. The on-going social/technological/economic changes create a competitive and challenging environment for companies to endure. To benefit from these changes, world economies partially depend on emerging Small and Medium Enterprises (SMEs) and their adaptability skills, and subsequently the development of an integrated capability to innovate has become the prime strategy for most of SMEs to subsist and grow. However, innovation and change are always somewhat bonded to an inherent risk development, which subsequently brings on the necessity of a revision of risk management approaches in innovative processes, whose importance SMEs tend to disregard. Additionally, little efforts have been made to improve and create empirical models, metrics and tools to assist SMEs managing latent risks in their innovative projects. This work seeks to present and discuss a solution to support SMEs in engaging on systematic risk management practices, which consists on an integrated risk assessment and response support web-based tool - Spotrisk® - designed for SMEs. On the other hand, an inherent subjectivity is linked with risk management and identification processes, due to uncertainty trait of its nature, for each individual perceives situations according to his own idiosyncrasy, which brings complications in normalizing risk profiles and procedures. This essay aims to bring insights concerning the support in decision-making processes under uncertainty, by addressing issues related with the risk behavior character among individuals. To address such issues, subjects of neuroscience or psychology are explored and models to identify such character are proposed, as well as models to improve presented tool. This work attempts to go beyond the restrictive aim of endeavoring on technical improvement dissertation, and in embraces an exploratory conceptualization concerning micro, small and medium businesses’ traits regarding risk characters and project risk assessment tools.

Bird-habitat associations in coastal rangelands of southern Brazil

Nearly all remnants of temperate grasslands in southeastern South America are used for livestock ranching and are subject to habitat degradation resulting from this activity. Exploring how habitat features affect the composition of grassland avifaunal communities is a first step to understand how current cattle-ranching management practices impact avian diversity. We used canonical ordination to test for relationships between five habitat variables and the composition of the bird community in coastal grasslands in southern Brazil. We sampled pastures with different heights, from overgrazed short-grass to tall herbaceous vegetation. We recorded 1,535 individuals and 27 species of birds. The first ordination axis indicated a strong contribution of mean vegetation height on the composition of the bird community, whereas the second axis revealed the influence of herbaceous vegetation patchiness and woody vegetation cover. Three groups of species were revealed by the ordination: one more diffuse associated with intermediate and tall herbaceous vegetation, another with short grass, and a third with vegetation patchiness and woody vegetation. Species restricted to tall herbaceous vegetation are negatively impacted from habitat degradation resulting from overgrazing and trampling by livestock, and mowing and burning of tall plants. Occurrence of these species in our study area is related with the presence of swales immediately behind the dune system and where remnants of tall vegetation persist. Birds of pastures with ample cover of short herbaceous plants, including one globally threatened species and six other restricted to short-grass habitat, apparently benefit from local livestock management practices. Woody vegetation possibly functions as a keystone structure, enabling the occurrence in grasslands of avian species that rely on shrubby habitat. Although livestock ranching promotes the diversity of habitats by creating distinct patches of vegetation height in grasslands, current management practices directed to the maintenance of short grass pastures may eliminate an entire subset of species, including regionally threatened taxa, and reduce avian diversity. The maintenance of large patches of tall herbaceous plants is needed to ensure the survival of species reliant on this type of grassland structure in our study area.

Percepción del riesgo de los agroquímicos en la localidad de Basavilbaso, Entre Ríos

El modelo agrario argentino actual se basa en el monocultivo de la soja para la exportación. Este cultivo aumentó de forma masiva a partir de la entrada de la soja transgénica resistente al herbicida glifosato, en los 90. Los plaguicidas han representado el gran sostén del crecimiento de la producción agropecuaria argentina. Debido al uso creciente que están teniendo y a la proximidad de los cultivos a los pueblos, los habitantes empiezan a percibir las prácticas de manejo y aplicación de plaguicidas como un riesgo para su salud y el medio ambiente de la zona. El clima de incertidumbre acerca de los impactos de los agroquímicos se percibe en las áreas productoras de soja, convirtiéndose en un conflicto entre expertos y población local. Con el estudio de este riesgo, del modo en que es percibido por la población y de los factores que causan dicha percepción, se ha observado que los problemas que generan la elevada percepción son principalmente las malas prácticas en la aplicación de los agroquímicos, la ausencia de regulación del organismo de control y la incertidumbre sobre los efectos que dichos productos pueden causar.

Organisational status and efficiency: the case of the spanish SOE "Paradores"

The purpose of this paper is to provide new evidence on the issue of the effect on public enterprises economic performance of the introduction of some given changes in organisational status and management practices, while keeping the enterprises under public control. Our approach is case study type and relies on comparative efficiency literature. We identify relevant changes on the organisational status of a State owned large hotel group along a period of twenty years, next we measure its annual efficiency indicators, and then evaluate to which extent the observed changes in economic performance can be attributable to the corresponding management reforms carried out. As a result we find that the formally more relevant change in organisational status (the enterprise passing to be a Limited Company), which implied a substantial increase in the enterprise autonomy, did not produce a significant improvement in its economic performance; a finding contrary to what we expected according to agency theory. However, a second relevant organisational change –five years later- when both the principal (government) and the agent (firm’s CEO) changed is consistently related to a significant improvement in economic performance. As a research implication we abide for use more precise agency theory statements; and as a practical implication we argue here that potentialities of improvement brought about by a formal-legal change in the status of the enterprise may require also –in order to actually improve firm’s efficiency- some changes in the firm’s key personal positions: supervisor (principal) and CEO (agent), in the sense that a change to a greater-autonomy for the enterprise it seems should come together a parallel new ‘management culture’. Practical implications Management good practises to apply to other public enterprise’s restructuring in order to improve their efficiency. It’s the first study on organizational changes and efficiency for an important Spanish public enterprise.

"Public on the outside, private on the inside": the organizational hybridization, sense of belonging and identity strategies of the employees of a public unemployment insurance fund in Switzerland

A number of studies show that New Public Management reforms have altered the current identity benchmarks of public officials, particularly by hybridizing values or management practices. However, existing studies have largely glossed over the sense of belonging of officials when their organization straddles the concerns of public service and private enterprise, so that the boundary between public and private sector is blurred. The purpose of this article is precisely to explore this sense of belonging in the context of organizational hybridization. It does so by drawing on the results of research conducted among the employees of a public unemployment insurance fund in Switzerland. On the one hand, the analysis shows how much their markers of belonging are hybrid, multiple and constructed in negative terms (with regard to the State), while indicating that the working practices of the employees point to an identity that is nevertheless closely bound with the public sector. On the other hand, the analysis shows that the organization plays strategically with its State status, by exploiting either its private or public identity in line with the needs related to its external image. The article concludes with a discussion of the results highlighting the strategic functionality of the hybrid identity of the actors.

Effects of increased drought and selective thinning on growth and resprouting of two coexisting Mediterranean oaks with contrasting leaf habit (Quercus ilex and Quercus cerrioides)

According to the IPCC (2007), the Mediterranean basin is expected to suffer important changes in temperature and precipitation in the next few decades, leading the climate warmer and dryer. Therefore, it is necessary to determine the possible effects of increased drought on species with different structural and physiological traits, to be able to predict possible changes in the structure and composition of Mediterranean forests. Moreover, it will be necessary to assess whether traditional management practices can mitigate the effects of climate change on these forests. The main aim of this study has been to analyze the effects of increased drought on the mortality, growth and resprouting patterns of two co-occurring Mediterranean oak species with contrasting leaf habit (the evergreen Quercus ilex and the winter-deciduous Quercus cerrioides), and to assess the effects of selective thinning on their response to increased drought. Our results show a differential effect of increased drought between species: no differences were observed in the growth of Q. ilex while Q. cerrioides reduced its growth under increased drought conditions. Selective thinning reduced the negative effects of increased drought on tree growth, although this beneficial effect tended to decrease during the experiment. Our results show that increasing aridity in Mediterranean areas can be a constraining factor for deciduous oaks, thus potentially causing their decline in mixed forests and favouring their substitution by the evergreen congeneric species. However, as seen in this study, management can strongly encourage growth both for deciduous and evergreen species, thus reversing the effects of increased water stress on Mediterranean coppices.

Apport de la systématique dans l'amélioration de la compréhension des systèmes de prise en compte des risques en entreprise

La gestion des risques est souvent appréhendée par l'utilisation de méthodes linéaires mettant l'accent sur des raisonnements de positionnement et de type causal : à tel événement correspond tel risque et telle conséquence. Une prise en compte des interrelations entre risques est souvent occultée et les risques sont rarement analysés dans leurs dynamiques et composantes non linéaires. Ce travail présente ce que les méthodes systémiques et notamment l'étude des systèmes complexes sont susceptibles d'apporter en matière de compréhension, de management et d'anticipation et de gestion des risques d'entreprise, tant sur le plan conceptuel que de matière appliquée. En partant des définitions relatives aux notions de systèmes et de risques dans différents domaines, ainsi que des méthodes qui sont utilisées pour maîtriser les risques, ce travail confronte cet ensemble à ce qu'apportent les approches d'analyse systémique et de modélisation des systèmes complexes. En mettant en évidence les effets parfois réducteurs des méthodes de prise en compte des risques en entreprise ainsi que les limitations des univers de risques dues, notamment, à des définitions mal adaptées, ce travail propose également, pour la Direction d'entreprise, une palette des outils et approches différentes, qui tiennent mieux compte de la complexité, pour gérer les risques, pour aligner stratégie et management des risques, ainsi que des méthodes d'analyse du niveau de maturité de l'entreprise en matière de gestion des risques. - Risk management is often assessed through linear methods which stress positioning and causal logical frameworks: to such events correspond such consequences and such risks accordingly. Consideration of the interrelationships between risks is often overlooked and risks are rarely analyzed in their dynamic and nonlinear components. This work shows what systemic methods, including the study of complex systems, are likely to bring to knowledge, management, anticipation of business risks, both on the conceptual and the practical sides. Based on the definitions of systems and risks in various areas, as well as methods used to manage risk, this work confronts these concepts with approaches of complex systems analysis and modeling. This work highlights the reducing effects of some business risk analysis methods as well as limitations of risk universes caused in particular by unsuitable definitions. As a result this work also provides chief officers with a range of different tools and approaches which allows them a better understanding of complexity and as such a gain in efficiency in their risk management practices. It results in a better fit between strategy and risk management. Ultimately the firm gains in its maturity of risk management.

Efecte de la recurrència dels incendis sobre la vegetació i el sòl a les zones de matollar del Macizo Central Ourensano

El matollar sec europeu format per Erica australis, Erica arborea, Pterosparum tridentatum, Halimium lasianthum i Calluna vulgaris com a espècies predominants és cremat en les serralades del Massís Central de forma repetida durant el pas dels anys. Això ha sigut, tradicionalment, a causa de la necessitat de mantenir-lo transitable per al bestiar, encara que altres circumstàncies s’han afegit actualment a aquesta necessitat, que incrementen el risc d’incendi d’aquesta comunitat, disparant-se el número d’incendis en els últims 30 anys. Sabent això, vam decidir realitzar un estudi a les zones de matollar que trobem al Massís Central situat a la zona del Concello de Villariño de Conso, a Ourense, per conèixer com es comporten les espècies característiques d’aquest tipus d’ecosistema després dels incendis, mitjançant la realització de mostrejos i perfils del sòl. D’aquesta manera hem volgut veure com es desenvolupen les espècies vegetals de matollar al llarg del temps, després de ser cremats. Gràcies a l’estudi hem pogut veure com el matollar observat te unes característiques que li permet sobreviure als incendis i tindre una capacitat de regeneració elevada després de patir aquesta pertorbació. Això es degut a la capacitat per rebrotar d’aquestes espècies arbustives i a la seva competitivitat. També hem vist com a necessari, donar un valor econòmic a la bona conservació de l’hàbitat, per tal de que la població local abandoni pràctiques de gestió forestal nocives, com el foc.
