description: Little research has focused on street-involved youths’ social relationships. As some scholars have suggested that leisure is inherently social, my research sought to understand whether participation in structured and/or unstructured leisure activities influence street-involved youths’ social relationships with other street-involved youths as well with members of the mainstream community. Written in the publishable paper format, this thesis is comprised of two papers, both of which utilize Foucauldian theory. In the first paper, I examine the impacts of street-involved youths’ participation in Health Matters, a leisure program for street-involved youths in Ottawa, Canada. In the second paper, I examine street involved youths’ unstructured leisure activities (e.g., leisure in non-programmed settings) and their subsequent social impacts. Based on my findings, I argue that street-involved youths use both structured and unstructured leisure to form crucial social connections to make their lives more bearable.

Die Autoren schlagen unter anderem Reformen bei der Besteuerung von Nahrungsmitteln vor: So sollte der ermäßigte Steuersatz für pflanzliche Produkte gesenkt und im Gegenzug die Mehrwertsteuervergünstigung für Fleisch und andere tierische Produkte gestrichen werden. Weitere Vorschläge werden analysiert, wie beispielsweise eine Reduzierung des Mehrwertsteuersatzes für kleinere Reparaturen und von Arbeitsleistungen für energetische Sanierung. Ein Teil der untersuchten Vorschläge betrifft auch Reformen, die sich erst nach europarechtlichen Änderungen umsetzen lassen. Quelle: www.umweltbundesamt.de

description: A major limitation of current reports on insect declines is the lack of standardized, long-term, and taxonomically broad time series. Here, we demonstrate the utility of environmental DNA from archived leaf material to characterize plant-associated arthropod communities. We base our work on several multi-decadal leaf time series from tree canopies in four land use types, which were sampled as part of a long-term environmental monitoring program across Germany. Using these highly standardized and well-preserved samples, we analyze temporal changes in communities of several thousand arthropod species belonging to 23 orders using metabarcoding and quantitative PCR. Our data do not support widespread declines of ÎÌ-diversity or genetic variation within sites. Instead, we find a gradual community turnover, which results in temporal and spatial biotic homogenization, across all land use types and all arthropod orders. Our results suggest that insect decline is more complex than mere ÎÌ-diversity loss, but can be driven by Î2-diversity decay across space and time. Quelle: Bericht
A software evaluation of the performance of both fixed and hybrid dynamic channel allocation schemes

Publisher: name: Swinburne
Year: 2024

description: This paper presents the results of a Monte-Carlo software simulation that evaluates the performance of a Fixed Channel Allocation (FCA) scheme for four different conditions namely, traffic distribution, terminal mobility, mean call duration and minimum call duration. The performance of the system has been assessed by evaluating the carried traffic and the call blocking percentage (including forced call termination) as a function of each of the four parameters. It is shown that knowledge of channel propagation alone is not sufficient enough for good frequency planning. Hence it is shown that the performance of a FCA scheme depends not only on channel propagation but also on traffic distribution, terminal mobility, mean call duration and minimum call duration. The performance of a Hybrid Dynamic Channel Allocation (HDCA) is also presented.
L’instant d’un ennui suivi d’Un parcours intertextuel et initiatique : des contes des frères Grimm à la poésie en prose
Creators: name: Chartrand, Marise
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2012

description: Cette thèse de création regroupe, dans la première partie, trente poèmes en prose sous le titre L’instant d’un ennui. Ils contiennent tous des références intertextuelles aux contes de Jacob et Wilhelm Grimm mais rompent avec la tradition du conte de fées. Ancrés dans le contexte contemporain, ils sont exempts de morale et ne sont écrits qu’à la première et à la deuxième personne dans le but de renforcer l’implication du lecteur. De plus, ils ne contiennent pas d’éléments merveilleux et se terminent de façon énigmatique afin de contourner l’aspect enfantin des contes des frères Grimm où tout doit être in fine compréhensible. Si la poésie en prose est le genre retenu, c’est principalement pour garder un style textuel propre au conte tout en faisant le lien avec l’aspect poétique qui se fait jour chez les frères Grimm. Plusieurs citations, témoignant du style poétique de ces auteurs, ont été intégrées à la création. Elles sont mises en italiques, pour en accentuer la visibilité. De plus, le passage des contes aux poèmes permet de « reconfigurer » les histoires que ces contes contiennent afin de les adapter au contexte social contemporain. Un premier volet théorique, intitulé Un parcours intertextuel, propose un survol des notions de l’intertextualité au fil du temps en réfléchissant notamment sur la place qu’y occupe la poésie, une question qui a suscité de nombreuses controverses. Puis l’analyse se penche sur deux types de transtextualité ayant aidé à la rédaction des poèmes et proposés par Gérard Genette dans Palimpsestes, l’intertextualité et l’hypertextualité. Ensuite, sous le titre Un parcours raconté, le second volet théorique examine le conte comme genre littéraire et se concentre sur l’œuvre des frères Grimm. Les questions relatives au processus d’initiation dans les contes sont évoquées afin de bien comprendre l’entreprise de ces auteurs qui constituent la base de cette recherche. Finalement, Un parcours réflexif offre une analyse de trois contes, La Belle au bois dormant, Jeannot et Margot et Oustroupistache, à la lumière des questions étudiées dans la partie théorique sur le processus d’initiation et l’intertextualité. Cette analyse se fait respectivement en lien avec les trois poèmes créés à partir de ces contes : Un dernier mot, Comme une Aero et Le tisserand du soir. En somme, cette thèse offre une perspective à la fois créative et théorique sur le conte, à la lumière de l’intertextualité et des théories de l’initiation.
Pets, Intimate Partner Violence, and the Abuser's Perspective

description: Domestic violence remains a serious social issue. In North America, millions of women are victimized each year, and many of these women are victims of violence at the hand of their intimate partners. A small but growing body of research on domestic violence has shown that companion animals are among the victims of such violence. Abuse of or threats to the pets are used to control, manipulate and emotionally abuse the female partner. However, the majority of this research has focused on the perspective of the abused female partner; the male perspective is missing. Through semi-structured interviews with ten incarcerated men who have committed intimate partner violence (IPV), this thesis explores the abuser’s motivations for abuse of the pet as well as their perspective of pets in the context of a violent relationship. The findings indicate that, contrary to previous research, most men do not abuse pets in the relationship, and in fact have positive relationships with their pets. Just as pets are sources of comfort for women in abusive relationships, pets can be sources of comfort and support for the abusive men as well. When incorporated into violence intervention and treatment programs, relationships with pets can provide a venue for men construct a masculine identity in a positive way, and the treatment of animals can illustrate how violence is not an effective solution.

description: This work of theoretical articulation, anchored on bibliographic research, considers as algorithmic platforms those networks with controlled access in which the user is governed by algorithms and his identity is continually redefined based on data provided by him or extracted from his activity. In order to understand the circumstances surrounding the user’s interaction with these platforms, the article proposes and develops categories that adapt and reformulate conceptual elements from a variety of sources. Interpellation is the algorithm approach to the user, which is recalibrated at each iteration and whose agency can be distributed in instances of alterity represented by the algorithm or other actors. This approach operates through profiling, i.e., the ad hoc definition of profiles grounded on the combination of user traits. Profiling, in turn, is consolidated by virtue of its assumption by the user, which corresponds to performativity. / Este trabalho de articulação teórica, ancorado em pesquisa bibliográfica, considera como plataformas algorítmicas as redes de acesso controlado nas quais o usuário é governado via algoritmos e sua identidade é redefinida continuamente com base em dados fornecidos por ele ou extraídos de sua atividade. Para entender as circunstâncias em torno da interação do usuário com essas plataformas, o artigo propõe e desenvolve categorias que adaptam e reformulam elementos conceituais de diversas origens. A interpelação refere-se à abordagem do usuário pelo algoritmo, que é recalibrada a cada iteração e cuja agência pode distribuir-se em instâncias de alteridade representadas pelo algoritmo ou por outros atores. Tal abordagem opera por meio da definição ad hoc de perfis a partir da combinação de traços do usuário, o perfilamento. Este, por sua vez, consolida-se em virtude de sua assunção pelo usuário, que corresponde à performatividade.

description: In 21st century, technology covered most of the segments of market, some ride-sharing companies made a turnaround in the taxi industry by the help of dynamic pricing system. This paper studies how Uber company attracting U.S. customers to work with them, moreover, how the surge pricing is influencing these processes. And also in paper, observed, how many driver-partners worked on the Uber platform and categorize them into particular groups according to their behavior types. And regular data of each the driver-partners from day they started work and quit or continued the work, the reasons why they worked in particular period, and why they made the Uber platform as their choice. And Uber has different services for both consumers and customers and some of them don’t use dynamic pricing system and so the reason is they try to give maximum comfort for its driver-partners. The Benenson Survey Group’s research work’s data is used in terms of show how attractive Uber platform.
Economic rationalism: short term gain for long term pain? A knowledge management analysis of the effect of organizational 'efficiency improvements' on competitive advantage

Year: 2024

description: Knowledge is, arguably, the most critical organizational resource affecting an organization's ability to develop, and sustain, a competitive advantage in the marketplace. Economic rationalism, it has been argued, with its focus on economic efficiency, will result in an increase in skills, capacities, and quality of the human resources of organizations, and a substantial improvement in the organization's productivity overall. Economic efficiency is also often defined as 'doing more with less'. This paper argues that three commonly practised efficiency practices - process reviews; downsizing; and internal competition - may result in a reduction of the organization's ability to learn and use knowledge, and therefore in the organization's ability to compete.

description: Oxidative stress (OS) drives cardiometabolic diseases. Intermittent hypoxia consistently increases oxidative stress markers. Obstructive sleep apnea (OSA) patients experience intermittent hypoxia and an increased rate of cardiovascular disease, however, the impact of OSA on OS markers is not clear. The objective was to assess relationships between OSA severity and biomarker levels. Patients with suspected OSA referred for a polysomnogram (PSG) provided fasting blood sample. Plasma levels of 8-isoprostane, 8-hydroxydeoxyguanosine (8-OHdG), and superoxide dismutase (SOD) were measured. The relationship between OSA and OS was assessed both before and after controlling for confounders (age, sex, smoking history, history of cardiovascular disease, ethnicity, diabetes, statin usage, body mass index (BMI)). 402 patients were studied (68% male, mean age ± SD = 50.8 ± 11.8 years, apnea-hypopnea index (AHI) = 22.2 ± 21.6 events/hour, BMI = 31.62 ± 6.49 kg/m²). In a multivariable regression, the AHI significantly predicted 8-isoprostane levels (p = 0.0008) together with age and statin usage; AHI was not a predictor of 8-OHdG or SOD. Female sex (p < 0.0001) and no previous history of cardiovascular disease (p = 0.002) were associated with increased antioxidant capacity. Circulating 8-isoprostane levels may be a promising biomarker of the severity of oxidative stress in OSA patients. Prospective studies are needed to determine whether this biomarker is associated with long-term cardiometabolic complications in OSA.

5-HT1A signaling

description: The 5-hydroxytryptamine (5-HT) system modulates numerous physiological and behavioural processes, and dysfunction within this system underlies many behavioural disorders, such as major depression. The 5-HT1A receptor is the primary somatodendritic autoreceptor that controls the firing rate of 5-HT neurons, but is also coupled to numerous signalling pathways. An understanding of 5-HT1A receptor signalling may lead to the development of antidepressant drugs that selectively target therapeutic pathways in treating depression. The 5-HT1A receptor is coupled to inhibitory G-proteins via its intracellular loops 2 and 3. Point mutations within these loops selectively uncouple receptor signalling pathways. In this thesis, I addressed whether mutant receptors’ uncoupling from signalling pathways is associated with alteration in G-protein interaction and coupling. Using bioluminescence resonance energy transfer (BRET) to monitor receptor-G-protein interactions, we show that both wild-type and mutant receptors demonstrate a saturable interaction with Gαi protein in unstimulated conditions. Addition of 5-HT increased the BRET signal for the wild-type 5-HT1A receptor, and this increase was blocked by a 5-HT1A receptor antagonist and G-protein blocker (pertussis toxin). Mutant receptors that were deficient in Gαi signalling, but not those that still signalled to Gαi, failed to respond to receptor activation with increased receptor-Gαi interaction. Pull down studies verified the basal and agonist-induced interaction of 5-HT1A receptors with Gαi proteins. In conclusion, we have shown that the 5-HT1A receptor interacts with Gαi consistent with a pre-coupled model and that 5-HT-induced activation enhances this interaction and requires specific residues in the intracellular loops.

description: Near-Real-Time (NRT) data transmission from distant observatory or sensor locations to data processing centre is a common feature shared by almost all ENVRIplus Research Infrastructures (RI) and is essential for rapid quality checking for the benefit of RI operators. NRT data transmission and quality control procedures are left to independent choices of the RIs responding to their specific needs and availability of infrastructural resources. However, a common approach to those NRT technologies would be extremely useful to coordinate response of RIs in case of environmental crisis.
 This document summarizes some key technologies used for data transmission, their availability, capabilities (in terms of bandwidth) and associated costs. It analyses requirements of research infrastructures and gives a summary of RIs best practises with respect to data transmission. Guided by the ENVRI Reference Model, further, potential harmonisation and standardisation approaches are discussed und special consideration of available sensor metadata standards and data transmission formats. In addition, common near real time quality routines and algorithms are presented.
 We will show in this deliverable that data transmission is not an easy task and hardly can be harmonized - in technical terms - across all ENVRIplus research infrastructures due to the diverse latency and bandwidth requirements and telecommunication availability e.g. at distant sites. However, emerging standards have a good potential to move the standardisation of data transmission and will move the standardisation level closer to the sensor which would in turn enable cross domain data processing services such as the identified common NRT quality control routines.

description: Data integration is a topic as old as environmental informatics, but still each single use case raises extensive individualefforts. We distinguish between organisational, methodical and technical issues. The Federal Environment Agency,Germany (Umweltbundesamt, UBA) has started a research and development project "Linked Environment Data"(LED) (UFOPLAN 3712 12 1003) in the summer of 2012, focussing on the applicability of Semantic Web technologyfor the technical integration. The resulting approach was named "semantic normalisationŁ. It is based on LinkedData patterns which are extended by shared RDF schemas and shared reference concept schemes. On top of this normalisation, applications can explore data from all participating datasets at one time, gathering knowledge fromdifferent sources.

description: The Poisson problem with homogeneous Dirichlet boundary conditions is considered on a triangle. The mapping between square and triangle is realized by mapping an edge of the square onto a corner of the triangle. Then standard Chebyshev collocation techniques can be applied. Numerical experiments demonstrate the expected high spectral accuracy. Further it is shown that finite difference preconditioning can be successfully applied in order to construct an efficient iterative solver. Then the convection-diffusion equation is considered. Here finite difference preconditioning with central differences does not overcome instability. However, applying the first order upstream scheme, we obtain a stable system. Finally a domain decomposition technique is applied to the patching of rectangular and triangular elements.
Lateral genetics: An approach to the cloning of potential human chorio-retinal X-linked genes.
Creators: name: Wong, Paul W.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1992
Subjects: subject: Biology, Molecular.

description: At present the cloning of disease genes relies on the application of forward and reverse genetics which requires prior knowledge of either the protein or the location of the gene locus underlying the disorder. In the present study a third alternative, a lateral approach, which focuses in at the level of expressed sequences (mRNA) is examined. This approach is used in the present study to explore its potential in the isolation of X-linked chorio-retinopathy candidate genes. The strategy developed for this approach uses a probe derived by the PCR amplification of a chorio-retinal cDNA library to screen a hamster/human X hybrid genomic library made in $\lambda$ phage vectors. The immediate achievement of this cross screen is the direct association of tissue expression with chromosome specificity. The initial application and evaluation of this approach is presented in the following thesis.

description: The increasing demand for polymer matrix composites (PMCs) from the airframe industry raises the issues of productivity, cost and reproducibility of manufactured PMC components. Performance reproducibility is closely related to the manufacturing technique. Resin transfer moulding (RTM) offers the advantage of flexible manufacturing of net-shape PMC components with superior repeatability starting from ready-to-impregnate dry reinforcements. An RTM apparatus was developed for manufacturing PMC plates and demonstrator components representative of actual, PMC components and PMC moulds made and used in the airframe industry. The RTM process developed in this work involved making net-shape dry carbon fibre preforms and impregnating them an epoxy resin, targeting mould applications. Thermal repeatability of different net-shape PMC components manufactured using the RTM apparatus developed in-house was investigated. Effects of bonding an outer copper plate onto the PMC material, targeting mould applications known as integrally heated copper tooling (IHCT), were explored. Heat conduction through the PMC components was studied using simulation models validated by experimental data obtained primarily by thermography. Manufactured PMC components showed good repeatability, particularly in terms of thermal behaviour. The IHCT technique was found to be well suited for mould applications. Expected advantages of thermography were materialised. Finally, the simulation models developed were in good agreement with experimental data.

description: The purpose of this thesis is to uncover and examine the processes that start-up entrepreneurs go through while designing and then developing their business models. This is done with the intent of deciphering the kind of development that might ultimately lead to a unique or innovative business model. This study uses primary qualitative data generated from interviews with founding entrepreneurs and managers who still participate in running the organization. Each of these organizations participates in the men’s retail market. The research design and methodology of this research uses a grounded-theory coding procedure to analyze the data. Three questions guide this research forward and the findings are threefold. First, for these organizations two business model design paths were followed, herein referred to as the path to ‘Alleviate Pain’ and as the path to ‘Adopt and Modify.’ Second, entrepreneurial leaders tended to act as arbiters when developing their business models, mediating between the set of information accrued during operations and three identified factors. Thirdly, new research into whether or not business model innovations are the result of ex-ante insights or ex-post operational learning is presented. And the findings tend to indicate that both ex-ante insights and ex-post learning are important, but their importance is temporally induced. Lastly, a brief discussion is carried out on how this research informs the entrepreneurial business model creation process (see entrepreneurial practicum) and how it adds to the current literature on business models and business model innovation.

description: Disinfectants and preservatives used as biocides may contain or release active substances (a.s.) that can form by-products with the surrounding matrices during their application which may be released into the environment. Over the past 40 years, several hundred of these so-called disinfection by-products (DBPs) have been detected after applications of biocides used for disinfection. Due to intensive research and further development of analytical capabilities, many new DBP classes, such as iodinated DBPs (I-DBPs), halonitromethanes (HNMs), haloacetamides (HaAms), or halomethanesulfonic acids were detected worldwide in various matrices and applications. Due to the possible hazards and risks for humans and the environment, frequently occurring DBP classes, such as trihalomethanes (THM), haloacetic acids (HAA) and nitrosamines (NDMA), have already been included in many legislations and given limit values. In the European Union, biocides are assessed under the Biocidal Products Regulation 528/2012 (BPR) regarding their efficacy, potential hazards, and risks to human health and the environment. However, the available guidance for the environmental risk assessment (ERA) of DBPs remains vague. To identify knowledge gaps and to further develop the assessment scheme for the ERA of DBPs, a literature search on the multiple uses of biocides and their formation potential of DBPs was performed and the existing process for ERA was evaluated. The results show knowledge gaps on the formation of DBP in non-aqueous systems and DBP formation by non-halogen-based biocidal active substances. Based on the literature research on biocides, a possible proposal of grouping a.s. to consider their DBP formation potential is presented to simplify future ERAs. However, this also requires further research. Until then, a pragmatic approach considering the DBPs formation potential of the active substances and the identified knowledge gaps need to be established for the environmental risk assessment of DBPs in the EU. © The Author(s) 2023
An Energy-Efficient Data Dissemination Protocol for Wireless Sensor Networks
Creators: name: Zhang, Dipu

description: Fast, reliable and energy-efficient data dissemination is one of the essential features for applications of wireless sensor networks (WSNs). Since the mobile sink was first introduced to the WSNs to prevent the hot spot problem which usually exists in static sink approaches, a number of data dissemination protocols that support sink mobility have been proposed in recent years. In the first part of this thesis, we present a comprehensive state-of-art overview of the major mobile sink protocols. Although many of them have made an effort to minimize the overhead of sink location updates and to maximize the energy efficiency, most of the protocols failed to concern one important fact that sensor energy consumed during the idling state is a major part of the overall energy consumption and dominates the network lifetime. Moreover, the protocols themselves are faced with all kinds of pending issues. Therefore, in the second part of this thesis, we propose E-Trail, a new data dissemination protocol for WSNs with mobile sinks, which combines a simple yet efficient trail generation scheme with a novel sleep-wake mechanism that lets the redundant sensors turn off their radio and sleep for a certain period of time. Experiments are carried out with the network simulator ns-2 to evaluate the performance of the proposed protocol. The simulation results indicate that E-Trail significantly saves sensor energy and improves network lifetime, while its other network performances such as data delay, control overhead and delivery rate are still maintained at a similar or even better level compared to selected protocols.

description: The aim of this study is to understand how leaders in the Canadian radio industry perceive the nascent personalized music streaming service industry, and how those perceptions inform their current business decisions. Over the last few years, Internet-based music services like Deezer and Rdio have launched in Canada, providing listeners with the opportunity of an alternative music experience to conventional broadcast radio. Through five interviews with experts representing terrestrial radio, on-demand services and regulation, three scenarios are presented for the future of conventional radio. In addition, a conceptualized listener profile is created using Grounded Theory Method. This profile buttresses the central finding of this research: should key political, economic and social factors remain in place, conventional radio is likely to continue to dominate as the leading commercial audio platform for Canadians in the years to come.

description: Background: Sepsis is the leading cause of death and disability in children. Every hour of delay in treatment is associated with an escalating risk of morbidity and mortality. The burden of sepsis is greatest in low- and middle-income countries where timely treatment may not occur due to delays in diagnosis and prioritization of critically ill children. To circumvent these challenges, we propose the development and clinical evaluation of a digital triage tool that will identify high risk children and reduce time to treatment. We will also implement and clinically validate a Radio-Frequency Identification system to automate tracking of patients. The mobile platform (mobile device and dashboard) and automated patient tracking system will create a low cost, highly scalable solution for critically ill children, including those with sepsis. Methods: This is pre-post intervention study consisting of three phases. Phase I will be a baseline period where data is collected on key predictors and outcomes before implementation of the digital triage tool. In Phase I, there will be no changes to healthcare delivery processes in place at the study hospitals. Phase II will involve model derivation, technology development, and usability testing. Phase III will be the intervention period where data is collected on key predictors and outcomes after implementation of the digital triage tool. The primary outcome, time to treatment initiation, will be compared to assess effectiveness of the digital health intervention. Discussion: Smart technology has the potential to overcome the barrier of limited clinical expertise in the identification of the child at risk. This mobile health platform, with sensors and data-driven applications, will provide real-time individualized risk prediction to rapidly triage patients and facilitate timely access to life-saving treatments for children in low- and middle-income countries, where specialists are not regularly available and deaths from sepsis are common.

description: Öffentlichkeitsbeteiligung ist ein wesentlicher Aspekt der modernen Lärmminderungsplanung. Dieser zielorientierte Ansatz ist in der EU-Umgebungslärmrichtlinie implementiert. Dementsprechend sind Bürger bereits bei der Erarbeitung von Lärmminderungsmaßnahmen und der Festsetzung ruhiger Gebiete angemessen zu beteiligen. Die zunehmende Forderung nach akustischer Lebensqualität lässt auch das juristische Interesse in den Vordergrund treten. So hat sich die Rechtsprechung insbesondere damit befasst, ob subjektive Rechte bei der Aufstellung eines Lärmaktionsplanes bestehen und welche Bindungswirkung durch diesen eintreten könnte. Um die Öffentlichkeitsbeteiligung zu stärken, hat das Umweltbundesamt zwei Projekte des ćÖkolöwe Ń Umweltbund Leipzig e. V̮. gefördert. ćMach´s leiser Ń Mitwirken bei der Lärmaktionsplanung in Leipzig̮ ist ein Modellprojekt, das in mehreren Stadtteilen Leipzigs durchgeführt wurde und gezeigt hat, wie Öffentlichkeitsbeteiligung als effektives Instrument zum Schutz vor Umgebungslärm in Deutschland definiert und umgesetzt werden kann. Es kann somit als Vorbild für andere Kommunen dienen. Quelle: zeitschrift-fuer-laermbekaempfung.de
description: Summary Public participation is a key aspect of modern noise abatement planning. This goal-oriented approach is implemented in the European Environmental Noise Directive. Citizens are already involved by the developing of concrete proposals of noise reduction measures and the determination of quiet areas. Moreover, the growing demand for acoustic quality of life indicates a higher juridical interest. Therefore, the courts have to answer several questions in this context. For example, the subjective right in the arrangement a noise action plan and its binding effect for private companies. In order to strengthen public participation further, the German Environment Agency supports two projects of the environmental alliance ̮Ökolöwe e.V. ̮Do it quieter Ń Participation of noise action planning in LeipzigŁ. These model projects demonstrate in several districts of Leipzig how public participation can be used as an effective instrument to protect the inhabitants against noise pollution. This model project may serve as an example in this respect. Quelle: zeitschrift-fuer-laermbekaempfung.de

description: This paper reports the findings of a qualitative study undertaken by the authors to investigate what students see when participating in a computer simulation session designed to support the development of conceptual understanding of the role of the sampling distribution in hypothesis testing. We have observed and documented the students’ assisted interaction with a dynamic and interactive computer simulation, and looked for patterns and themes arising from the data. On the basis of the data collected, we have identified four developmental stages through which the students progressed during the activity, and we have termed these stages as recognition, integration, contradiction and explanation. The identification of the stages has given us some direction for the development of further computer interactions.

description: Dynamic balancing of computation and communication load is vital for the execution stability and performance of distributed, parallel simulations deployed on shared, unreliable resources of large-scale environments. High Level Architecture (HLA) based simulations can experience a decrease in performance due to imbalances that are produced initially and/or during run-time. These imbalances are generated by the dynamic load changes of distributed simulations or by unknown, non-managed background processes resulting from the non-dedication of shared resources. Due to the dynamic execution characteristics of elements that compose distributed simulation applications, the computational load and interaction dependencies of each simulation entity change during run-time. These dynamic changes lead to an irregular load and communication distribution, which increases overhead of resources and execution delays. A static partitioning of load is limited to deterministic applications and is incapable of predicting the dynamic changes caused by distributed applications or by external background processes. Due to the relevance in dynamically balancing load for distributed simulations, many balancing approaches have been proposed in order to offer a sub-optimal balancing solution, but they are limited to certain simulation aspects, specific to determined applications, or unaware of HLA-based simulation characteristics. Therefore, schemes for balancing the communication and computational load during the execution of distributed simulations are devised, adopting a hierarchical architecture. First, in order to enable the development of such balancing schemes, a migration technique is also employed to perform reliable and low-latency simulation load transfers. Then, a centralized balancing scheme is designed; this scheme employs local and cluster monitoring mechanisms in order to observe the distributed load changes and identify imbalances, and it uses load reallocation policies to determine a distribution of load and minimize imbalances. As a measure to overcome the drawbacks of this scheme, such as bottlenecks, overheads, global synchronization, and single point of failure, a distributed redistribution algorithm is designed. Extensions of the distributed balancing scheme are also developed to improve the detection of and the reaction to load imbalances. These extensions introduce communication delay detection, migration latency awareness, self-adaptation, and load oscillation prediction in the load redistribution algorithm. Such developed balancing systems successfully improved the use of shared resources and increased distributed simulations' performance.

description: This thesis begins with the hypothesis that the role of ideas in urban and global development is understudied and understated in comparison to studies that privilege economic and political analyses. The thesis generates two related models that seek to provide a comprehensive means of analyzing both the political economic constraints of development as well as the ideational limits that are overlooked by conventional models. The political economic model adapts constructivist principles to explain the structural limits on urban development that emerge from the contemporary global political economy. The second model draws on previous work done in the field of policy diffusion to posit four relational ways in which ideas are adapted and localized. The thesis argues that political economy analyses provide a comprehensive but mostly macro-level analysis and often fail to adequately understand individual thinking outside of the rational actor model. The ideational adaptation model corrects for this, providing a detailed micro-level analysis that is founded on the political economic framework. Together, the two models provide a comprehensive understanding of the ideational limits and political economic constraints at work in any given development scenario. In order to demonstrate the utility of the combined models (termed combined conceptual approach), the thesis applies the models to four different applications. Three examples are historical secondary source examples (educational philosophy, international business councils, and water sanitation) related to the history of Shanghai and China, and the impact of foreigners on their development vision, strategies, and practice. One application is a case study of Shanghai’s Expo 2010, which uses original data established through high-level interviews with Expo participants. The use of the combined conceptual approach shows how the interpersonal and inter-institutional adaptation and localization of ideas affect the way we understand the concept of legitimate best practice in urban development. The combined conceptual approach highlights the role that human thought, emotions, and psychology play in urban development. It links political economic activity to constructed bonds of trust, learning, the mentality of competition, and soft forms of coercive power (hegemonic ideas, leadership, and conditionality). Finally, the most important contribution of the combined conceptual approach is that it allows for an analysis of both the macro- and micro-levels of development in a relational and holistic fashion.
