Community Based Coastal Monitoring: Developing Tools For Sustainable Management

Rickard, Darcel January 2008 (has links)
Burgeoning coastal development, recreational use, and the future affects of climate change are placing increasing strain on regulators to manage risk associated with coastal hazards. Low-lying coastal communities in particular are vulnerable to a range of natural hazards including coastal erosion, storm surge inundation, tsunami and water safety that come with varying levels of risk to life and property. New Zealand's coastal hazard monitoring network is patchy and resources are limited. As a consequence there is considerable potential for coastal communities are going to need to take a more active role in monitoring their environment and building data bases and knowledge that can be used to better manage their coast. This paper describes simple methodologies based on the needs of various community groups and sound science principles that can be used to monitor beaches and the coastal environment. By employing these tools councils, technical experts and community groups will be able to make better-informed decisions for managing activities in the coastal environment. One of the keys to the successful uptake of a monitoring programme by a community group is its relevance to the group. The programme and the tools provided must fit the interests, needs, capability and resources of the group. This project develops tools for coastal monitoring and targets coastal community groups such as Coast Care, Coastal Hapu, Secondary Schools, and Surf Life Saving Clubs. The monitoring methodologies have been developed in consultation with Tainui ki Whaingaroa hapu, Raglan Area School, and the Waikato Beach Care and Coast Care Bay of Plenty. Successful methodologies for measuring changes on the coast are also those that are matched to the type of beach, use appropriate equipment, collect structured data, provide data to which analysis can be applied, incorporate local knowledge of the environment, and feed results back to the community and other interested parties such as councils and science organisations. This project provides the target groups with simple monitoring methodologies, field forms/checklists, and appropriate survey and measurement equipment (which have undergone field trials) to carry out coastal monitoring. A web-based facility has been developed to input, check and store data; and provide immediate feedback using graphs and images. It also provides background information on coastal processes relevant to monitoring programmes. In this manner, a scientifically robust data set is collected and stored within a secure and future proofed archive, providing valuable information to coastal groups for years to come. Although the primary objective of this research is to develop a means for coastal communities to monitor changes in their environment, there are additional benefits associated with engaging communities in the study of their environment. These benefits include increasing awareness of coastal hazards, capacity building, providing valuable educational resources, and improving the temporal and spatial data coverage of information for the New Zealand coastline.

Améliorer l'exactitude de l'auto-évaluation : quels dispositifs pour quels apprenants ? / Improving self-monitoring accuracy : which tools for which learners?

Maillard, Adeline 27 November 2015 (has links)
L'auto-évaluation est un processus métacognitif central dans le cadre d'un apprentissage en autonomie. Des décennies de recherche ont montré, toutefois, que les apprenants n'auto-évaluaient pas leurs performances futures avec exactitude, conduisant les chercheurs à essayer de mieux comprendre le processus d'auto-évaluation afin d'en améliorer l'exactitude. La majeure partie des travaux effectués sur le sujet ont, toutefois, été réalisés dans des situations peu écologiques et impliquent des tâches d'apprentissage simples (e.g. l'apprentissage associatif) ou classiques (e.g. compréhension de textes linéaires). Cette thèse présente trois études qui se centrent autour de l'exactitude de l'auto-évaluation dans des contextes plus écologiques. Ces études testent l'efficacité de divers outils d'aide à l'auto-évaluation sur une tâche d'apprentissage intégrée aux enseignements des participants. Elles considèrent également des caractéristiques propres à la tâche ou à l'apprenant. Ainsi, la première étude combinait plusieurs outils d'aide à l'auto-évaluation (incitations à la prise de conscience des stratégies utilisées et de leur pertinence, et auto-explications) afin d'améliorer l'exactitude des auto-évaluations sur des connaissances déclaratives et procédurales. Une deuxième étude explorait l'effet des cartes conceptuelles en tant qu'outil d'aide à l'auto-évaluation. L'efficacité des cartes conceptuelles sur l'exactitude de l'auto-évaluation et l'apprentissage a été testée selon le mode de leur utilisation (construction vs. consultation), le moment de leur présentation (simultanément à l'apprentissage vs. en différé) et le niveau d'expertise des apprenants (experts vs. novices). Enfin, la troisième étude évaluait si un entraînement relativement long à l'utilisation des cartes conceptuelles permettait d'en faire un outil efficace pour améliorer l'exactitude de l'auto-évaluation et l'apprentissage. Les résultats obtenus lors de ces trois études n'ont pas confirmé nos hypothèses relatives à l'efficacité des outils d'aide à l'auto-évaluation sur l'exactitude de l'auto-évaluation. Les résultats montrent, cependant, que les participants auto-évaluaient avec plus d'exactitude des connaissances déclaratives que procédurales (Étude 1). Les résultats ont également répliqué, sur une tâche plus écologique, l'effet positif du niveau des connaissances antérieures dans le domaine d'apprentissage sur l'exactitude de l'auto-évaluation, généralement démontré dans la littérature sur des tâches de laboratoire (Étude 2). Finalement, les résultats ont révélé que la durée de l'entraînement à la réalisation de cartes conceptuelles n'avait pas d'effet sur l'efficacité des cartes conceptuelles (Étude 3). La discussion de ces résultats est organisée autour de quatre points principaux. Une première partie revient sur la question de l'adaptation des outils d'aide à l'auto-évaluation au niveau d'expertise des apprenants. Une seconde partie traite de l'adéquation des outils d'aide à l'auto-évaluation avec le type de connaissances évaluées. Une troisième hypothèse se centre sur la nature de l'exactitude de l'auto-évaluation mesurée, afin expliquer l'absence d'effet des outils d'aide à l'auto-évaluation testés. Finalement, le rôle des variables motivationnelles dans l'exactitude de l'auto-évaluation sera abordé comme une piste de travail pertinente. / Self-monitoring is a key metacognitive process in self-regulated learning. Decades of research, however, showed that learners are inaccurate in evaluating their own performance which led researchers to focus on understanding the self-monitoring process to ultimately improve self-monitoring accuracy. Most work on the topic was conducted in low ecological contexts and implied only easy (e.g., associative learning) or classical (i.e. comprehension of linear texts) learning tasks. The present thesis offers three studies that focused on self-monitoring in ecological contexts. These studies explored the efficiency of several self-monitoring tools on a learning task integrated in participant's school formation setting and took into account task and learner characteristics. The first study used several self-monitoring help tools jointly (prompts aimed to make the learner aware of the strategies is used and their relevance, and self-explanations) in order to improve self-monitoring accuracy about declarative and procedural knowledge. The second study explored concept maps as a self-monitoring tool and tested their effect on learning in different conditions. The experimental manipulations were presentation mode (construction vs. consultation), moment of presentation (simultaneously to learning vs. delayed) and learners' expertise level (experts vs. novices). Finally, the third study assessed whether a long training to concept maps use was efficient enough to make this tool a relevant one to improve self-monitoring accuracy and learning. Results of the three studies did not confirm our hypothesis about self-monitoring tools efficiency on self-monitoring accuracy in a subsequent task. Results, however, showed that participants were more accurate when they evaluated declarative knowledge than procedural knowledge (Study 1). They also replicate, in a more ecological task, the positive effect of prior knowledge level about the target learning content on self-monitoring accuracy traditionally highlighted in the literature relying on laboratory learning task (Study 2). Finally, the training duration to use concept maps did not affect concept map efficiency (Study 3). Discussion of the present findings is centered on four main points. A first point discusses the suitability of self-monitoring tools as a function of learners' level of expertise. A second line of discussion deals with the adequacy between self-monitoring tools and the nature of knowledge which is evaluated. A third hypothesis regards the nature of self-monitoring accuracy which was measured, in order to explain the absence of effect of the self-monitoring tools we tested. Finally, the role of motivational variables surrounding self-monitoring accuracy is discussed as a compelling avenue.

Embracing Transformative Technology to End Worker Exploitation : How Individual Resistance to Change Management Can Explain the Limited Adoption of Worker Monitoring Tools in Multinational Organizations.

Kahn, Alek, Jiang, Yiping, Nilsson, Måns January 2021 (has links)
Background: The unethical treatment of factory workers is widespread, especially in developing countries. There is no international legal body with the jurisdiction to uphold universal labor rights. Hence, the responsibility to ensure worker well-being falls upon the multinational organizations that operate the supply chain. These focal firms often use social auditing; however, recent research reveals that this approach does not incorporate workers' experiences on a consistent basis. To address these shortcomings, a new technology has enabled organizations to connect directly with factory workers, we term the technology digital reporting tools (DRT).  Problem: Even though DRT potential is supported, their adoption rate amongst multinational organizations remains minimal. The benefits of these tools cannot be leveraged without firm implementation. In fact, the estimated market size for socially sustainable tools in global supply chains significantly outweighs their investment rates. This discrepancy must be explained to advance the industry.  Purpose: This thesis intends to deepen the understanding of individual and group level resistance within the change management field by researching a phenomenon that combines technology and social sustainability: DRTs. By recognizing the internal subjective experiences of potential users of DRT technology, we ultimately hope to inform DRT-providers and focal firms of internal and unrealized bottlenecks that hinder the adoption of these tools.  Method: The thesis employs an inductive research approach with a qualitative research design based on 8 semi-structured interviews. All respondents are potential users of the technology within focal firms.  Result: Upon researching the experience of potential users, we find that their willingness to suggest DRT to upper management is the primary mechanism that impacts adoption. We partitioned willingness to suggest into two aggregate dimensions: perceived acceptance of upper management and organizational culture. We find potential users hold an internal need to pitch DRT to upper management in monetary terms. Furthermore, half of DRT utility was unknown by respondents. Lastly, we correlate the sub-theories of change management to the different factors we identified.

Monitorovanie činností zamestnancov – praktiky a používané nástroje / Monitoring employee activity - practices and tools

Zdechovan, Ján January 2015 (has links)
This thesis discusses surveillance in the work environment. The topic is too extensive, that´s the reason its focus is mainly on electronic employee monitoring. The basic concepts are explained in the beginning of the thesis, which is subsequently followed by a simple survey oriented on the opinions on employee surveillance. The center of this thesis is an analysis of legal, technical and ethical aspects, which also reviews different monitoring practices. Identified practices are used for defining monitoring possible scenarios. The contribution of this work is the evaluation of employee monitoring practices and establishing a ranking of monitoring tools that can serve as a decision making tool for organizations. This thesis uses not only theoretical knowledge from literature, but also incoporates comments and opinions from experts.

Traçage des intrusions de CO2 dans les aquifères d'eau douce par les méthodes multi-isotopiques / Development of indirect indicators for CO2 intrusion into freshwater

Humez, Pauline 20 December 2012 (has links)
Cette étude porte sur l'impact des fuites de CO2 provenant d'un réservoir géologique de stockage de CO2 sur un aquifère d'eau douce. Elle se distingue des autres études, réalisées sur le même thème, par la recherche et l'application, depuis l'échelle du laboratoire jusqu'à celle d'un site pilote, de nouveaux outils de monitoring et d'approche isotopique destinés à la détection précoce de fuite de CO2. Afin de tester ces outils, des échantillons solides et liquides provenant de l'aquifèrestratégique de l'Albien du Bassin de Paris ont été prélevés, analysés et utilisés pour une étude expérimentale en batch. Cette expérience permet de contraindre et de comprendre précisément les interactions eau-roche-CO2 et les réponses isotopiques. Une application grandeur nature en Norvège a permis de mettre en place ce programme isotopique et de suivre l'évolution de la composition isotopique en distinguant les processus et phénomènes naturels et les processus reliés à l'injection de CO2. Ces deux cas d'étude appliqués au contexte de détection de fuite de CO2 ont permis de choisir les outils isotopiques les meilleurs comme indicateurs indirects de la présence de CO2, dans le cas particulier des systèmes étudiés. L'efficience de ces outils isotopiques réside dans l'enregistrement de la trace laissée par la présence de CO2 au cours d'interactions eau/roche/CO2. L'utilisation de tels outils nécessite une méthodologie rigoureuse abordée dans ce manuscrit et nécessite d'être adaptée aux spécificités des sites envisagés. / This study deals with the impact of CO2 leakages out of geological storage into overlying freshwater aquifers. Compared to other existing studies, the major added value of this study lies, on the one hand, in the research of new monitoring tools and isotopic approach in the context of CCS aiming at early and sensitive detection of CO2 leakage and, on the other hand, in the application of these tools at the (limited) laboratory scale as well as at field scale. In order to test these tools, solid and liquid materials were sampled out of the major strategic drinking water Albian aquifer in the Paris Basin (France). We have then precisely characterized and used them within a batch experiment. This experiment yields interesting results which help understanding and constraining precisely the water-rock-CO2 interactions as well as the isotopic responses. A real scale application of the method was then performed in Norway. It was an opportunity to develop this isotopic program and to track the isotopic evolution composition, while differentiating the natural processes and the system response tothe CO2 injection. When applied to the detection of CO2 leakage context, the two case studies open the way for choosing the “best” isotopic tools as indirect indicators of CO2 presence in these specific systems. The efficiency of these isotopic tools comes from the recording of the CO2 footprint all along the water-rock-CO2 interactions. Using such tools imposes a rigorous methodology, which is tackled inthis manuscript. Furthermore, future application will require adapting to the specifics of a proposed site.
