description: Nucleation is the first step in the formation of a new phase in a thermodynamic system. The Classical Nucleation Theory (CNT) is the traditional theory used to describe this phenomenon. The object of this thesis is to investigate nucleation beyond one of the most significant limitations of the CNT: the assumption that the surface tension of a nucleating cluster of the new phase is independent of the cluster’s size and has the same value that it would have in the bulk of the new phase. In order to accomplish this, we consider a microscopic, two-dimensional Lattice Gas Automata (LGA) model of precipitate nucleation in a supersaturated system, with model input parameters Ess (solid particle-to-solid particle bonding energy), Esw (solid particle-to-water particle bonding energy), η (next-to-nearest neighbour bonding coeffiicent in solid phase), and Cin (initial solute concentration). The LGA method was chosen for its advantages of easy implementation, low memory requirements, and fast computation speed. Analytical results for the system’s concentration and the crystal radius as functions of time are derived and the former is fit to the simulation data in order to determine the system’s equilibrium concentration. A mean first-passage time (MFPT) technique is used to obtain the nucleation rate and critical nucleus size from the simulation data. The nucleation rate and supersaturation are evaluated using a modification to the CNT that incorporates a two-dimensional, radius-dependent surface tension term. The Tolman parameter, δ, which controls the radius-dependence of the surface tension, decreases (increases) as a function of the magnitude of Ess (Esw), at fixed values of η and Esw (Ess). On the other hand, δ increases as η increases while Ess and Esw are held constant. The constant surface tension term of the CNT, Σ0, increases (decreases) with increasing magnitudes of Ess (Esw) fixed values of Esw (Ess), and increases as η is increased. Together, these results indicate an increase in the radius-dependent surface tension, Σ, with respect to increasing magnitude of Ess relative to the magnitude of Esw. Σ0 increases linearly as a function of the change in energy during an attachment or detachment reaction, |ΔE|, however with a slope less than that predicted for a crystal that is uniformly packed at maximum density.

description: Prior research has shown that negative attitudes toward mathematics are linked to decreased achievement and participation, but it is unclear what factors influence children’s attitudes toward mathematics. Thus, the overarching goal of this study was to understand the relationship between outside sources and children’s views. Specifically, this study investigated elementary students’ experiences with and views of mathematics and mathematicians, and the ways that their views may be influenced by popular media representations, parents’ views, and teachers’ views of mathematics and mathematicians. Additionally, the study examined whether there were differences between girls’ and boys’ views and between younger (Grade 4) and older (Grade 8) elementary students’ views of mathematics and mathematicians. Framed by a social constructivist and feminist epistemological stance, the study employed a multi-method framework comprised of questionnaires (n = 156), drawings of mathematicians (n = 94), and focus group interviews (five interviews, involving 21 participants) with students; an analysis of children's media (43 examples across five media types); interviews with parents (11 interviews, involving 13 participants); and interviews with teachers (nine interviews, involving 10 participants). In terms of their relationships with mathematics, the student, parent, and teacher participants’ views were encouraging, both in terms of perceptions of themselves as learners of mathematics and of the utility of mathematics. However, the manner in which the participants conceptualized mathematics tended to lack breadth, often focusing on arithmetic and financial mathematics. Similar conceptions of mathematics were evident in the media representations. Moreover, media portrayals of mathematicians and mathematically proficient people tended to perpetuate stereotypes. Despite their awareness of these stereotypes, the participants often lacked alternative representations to challenge these views. Indeed, the lack of exposure to a variety of representations of both mathematics and mathematicians contributed to the participants’ reliance on views that were often narrow and stereotypical.

description: Mitochondrial dysfunction has been implicated as one of the primary causes of Parkinson's disease (PD). The proteins PINK1, a serine-threonine kinase, and Parkin, an E3 ubiquitin ligase, are mutated in many genetic cases of PD. In healthy individuals, Parkin is recruited to damaged mitochondria and leads to autophagic degradation of mitochondria in a process termed mitophagy. Following depolarization of the mitochondrial membrane, PINK1 is stabilized on the outer mitochondrial membrane, and triggers Parkin translocation from the cytosol to mitochondria. Precisely how this phenomenon is regulated is still unclear. We employed RNA interference (RNAi) technology in a 384-well format to identify novel genes that are required for Parkin recruitment to mitochondria. We identified ATPase inhibitory factor 1 (IF1) as the strongest hit required for Parkin recruitment following treatment with the protonophore CCCP. We show that IF1 is upstream of PINK1 and Parkin, and required to sense mitochondrial damage by allowing the loss of membrane potential. In cells treated with CCCP, the absence of IF1 permits the ATP synthase to run freely in reverse, consuming ATP to maintain potential across the inner mitochondrial membrane, thus blocking PINK1 and Parkin activation. Interestingly, Rho0 cells, that lack mitochondrial DNA, have downregulated endogenous expression of IF1 in order to maintain mitochondrial function. Overexpression of IF1 in Rho0 cells results in the depletion of mitochondrial membrane potential and the initiation of mitophagy. These data demonstrate a unique role for IF1 in the regulation of mitochondrial quality control that has not been explored in the etiology of PD.

description: The goal of this work was to propose a novel, long-term stable, bifunctional, carbon-free (CF-)GDE design for alkaline energy converters. This is achieved by understanding how the electrochemical activity of GDEs is affected by the pore size and the surface properties (hydrophobic and hydrophilic) of the electrode. In addition, combinations of different pore sizes and surface properties (hydrophobic and hydrophilic) and their influence on electrochemical activity will also be investigated. It is also necessary to understand the difference between the designed CF-GDE and the state-of-the-art carbon-based GDEref. The goal of proposing a novel, long-term stable, bifunctional CF-GDE design for alkaline energy converters was successfully achieved. The benchmark of the developed CF-GDE revealed that it is a competitive bifunctional GDE for metal-air batteries and unitized regenerative fuel cells and potentially for electrolyzers. Therefore, it is among the most advanced gas diffusion electrodes for alkaline applications.

description: Rehearsal-based Continual Learning (CL) has been intensely investigated in Deep Neural Networks (DNNs). However, its application in Spiking Neural Networks (SNNs) has not been explored in depth. In this paper we introduce the first memory-efficient implementation of Latent Replay (LR)-based CL for SNNs, designed to seamlessly integrate with resource-constrained devices. LRs combine new samples with latent representations of previously learned data, to mitigate forgetting. Experiments on the Heidelberg SHD dataset with Sample and Class-Incremental tasks reach a Top-1 accuracy of 92.5% and 92%, respectively, without forgetting the previously learned information. Furthermore, we minimize the LRs' requirements by applying a time-domain compression, reducing by two orders of magnitude their memory requirement, with respect to a naive rehearsal setup, with a maximum accuracy drop of 4%. On a Multi-Class-Incremental task, our SNN learns 10 new classes from an initial set of 10, reaching a Top-1 accuracy of 78.4% on the full test set.

description: Abstract Background Opioid agonist therapy (OAT) uptake has been associated with multiple positive health outcomes among people who inject drugs (PWID). This study evaluated the pattern of OAT uptake among PWID in two consecutive national bio-behavioral surveillance surveys (2010 and 2014) in Iran. Methods Data were obtained from two national bio-behavioral surveillance surveys (N₂₀₁₀ = 1783 and N₂₀₁₄ = 2166) implemented using convenience sampling at the harm reduction facilities and street venues in 10 geographically diverse urban centers across Iran. Multivariable logistic regression models were built to determine the correlates of OAT uptake for the 2014 survey, and adjusted odds ratios (AORs) along with 95% confidence intervals (CI) were reported. Results The prevalence of OAT uptake decreased from 49.2% in 2010 to 45.8% in 2014 (P value = 0.033). OAT uptake varied across the studied cities ranging from 0.0 to 69.3% in the 2010 survey and 3.2 to 75.5% in the 2014 survey. Ever being married (AOR = 1.40; 95% CI 1.12, 1.75), having a history of incarceration (AOR = 1.56; 95% CI 1.16, 2.09), and human immunodeficiency virus (HIV) sero-positivity (AOR = 1.63; 95% CI 1.08, 2.50) were associated with OAT uptake. Conversely, PWID who reported using only non-opioid drugs (AOR = 0.43; 95% CI 0.26, 0.71) and those who reported concurrent use of opioid and non-opioid drugs (AOR = 0.66; 95% CI 0.51, 0.86) were less likely to uptake OAT. Conclusions Although OAT uptake among PWID in Iran is above the 40% threshold defined by the World Health Organization, there remain significant disparities across urban settings in Iran. Importantly, the OAT services appear to be serving high-risk PWID including those living with HIV and those with a history of incarceration. Evaluating service integration including mental health, HIV and hepatitis C virus care, and other harm reduction services may support the optimization of health outcomes associated with OAT across Iran.

description: Zeolite membranes are considered to be a promising alternative to polymeric membranes and they have the potential to separate gases under harsh conditions. Silicalite-1 membranes in particular are easy to prepare and suitable for several industrial applications. In this research project, silicalite-1/ceramic composite membranes were prepared using the pore plugging hydrothermal synthesis method and supports with zirconium oxide and/or titanium oxide as active layers. The effect of the support’s pore size on the morphology and permeation performance of the prepared membranes was investigated using five supports with different active layer pore sizes in the range of 0.14 – 1.4 m. The prepared membranes were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), electron diffraction spectrometer (EDS), single gas and binary gas mixtures permeation tests. The results confirmed the presence of a typical silicalite-1 zeolite structure with a high internal crystalline order grown inside the pores of the active layer of the supports, with a dense film covering most of the supports active layers. Silicalite-1 crystals in the prepared membranes were preferably oriented with either a- or b-axes perpendicular to the support surface. Single gas permeation results illustrated that the observed permeances were not directly related to the kinetic diameter of permeants. Instead, the transport of the studied gases through the prepared membranes occurred by adsorption followed by surface diffusion mechanism. Binary gas tests performed with CO2 and N2 mixtures showed that the prepared membranes were selective and very permeable with CO2/N2 permselectivities up to 30 and a CO2 permeances in the order of 10-6 mol m-2 Pa-1 s-1. A model was developed, based on Maxwell−Stefan equations and Extended Langmuir adsorption isotherm, to describe the transport of binary CO2 and N2 mixtures through the prepared silicalite-1 membranes. The model results showed that the exchange diffusivities (D12 and D21) were less dependent on the feed pressure and feed composition compared to the permeances and the permselectivities. Hence, they are more appropriate to characterize the intrinsic transport properties of the prepared silicalite-1 membranes.

High-precision observations of relativistic binary and millisecond pulsars

Publisher: name: Swinburne

description: The technique of pulsar timing reveals a wealth of new information when a precision of ~1 μs or better is reached, but such precision is difficult to achieve. This thesis describes a series of very high precision timing observations that improve our knowledge of the targeted pulsar systems. We begin by describing a newly-developed baseband recording and coherent dedispersion system (CPSR2), along with a new object-oriented software development environment for pulsar data processing. Data obtained with this new instrument during a 3 year observing campaign at the Parkes 64m radio telescope are analysed in a number of novel ways. The mean profile of PSR J1022+1001 is shown to be stable on timescales of a few minutes, in contrast with previously published claims. We obtain a level of precision an order of magnitude better than any previous timing of this pulsar. In addition, we observe dramatic changes in the mean profile of the relativistic binary pulsar J1141–6545, which broadens by ~50% over the time span of our observations. This is interpreted as evidence for secular evolution of the line of sight to the emission cone, caused by General relativistic geodetic precession which tilts the spin axis of the pulsar. High precision CPSR2 observations of the extraordinary double pulsar binary system are presented and we construct calibrated, mean polarimetric profiles for PSR J0737–3039A, in two frequency bands. These profiles provide a reference against which future profile evolution may be detected, given that we expect geodetic precession to alter the observed mean profile on an even shorter time scale than for PSR J1141–6545. The bulk of this thesis involves timing a selection of millisecond pulsars whose physical characteristics should allow the highest precision to be obtained. We measure several new proper motions and parallax distances. Shapiro delay is used to constrain the inclination angles and component masses of several of the binary systems in our source list. In addition, subtle periodic variations of the orbital parameters of two nearby binary millisecond pulsars are detected and attributed to annual orbital parallax, providing additional constraints on their three-dimensional orbital geometries. Future observations of these two sources may lead to more stringent tests of post-Keplerian gravitational theories. Finally, we use the timing residuals of one very stable source (PSR J1909–3744) as a reference against which we time PSR J1713+0747 with a root-mean-square precision of 133 ns, amongst the best timing residuals ever obtained. This result is an important step in the search for long-period gravitational waves using pulsar timing arrays.

description: The cryopreservation of cells and tissues requires the addition of a cryoprotectant in order to prevent cellular damage caused by ice. Unfortunately, common cryoprotectants such as DMSO and glycerol exhibit significant toxicity which makes their use unfeasible for many clinical procedures. Our laboratory is interested in the development of alternative, non-toxic cryoprotectants which possess ice recrystallization inhibition (IRI) activity. Potent IRI activity has recently been discovered in certain small molecules, but the structural features required for this process are unclear. Herein we report the development of a library of O-aryl glycosides in order to probe the importance of electron density and hydrophobic moieties for IRI activity. It was found that the degree of electron density at the anomeric oxygen does not correlate with IRI ability in para-substituted aryl glycosides, nor does changing the position of the aryl substituent impart a predictable effect on activity. However, the addition of hydrophobic alkyl or acyl chains was beneficial for IRI activity; generally, increasing chain length was found to correlate with increasing activity. In some instances, an optimal alkyl chain length was identified, after which continued lengthening results in a loss of potency. We conclude from this study that a certain extent of hydrophobic character is beneficial for the IRI activity of aryl glycosides, and that a balance between hydrophobicity and hydrophilicity is required for optimum IRI ability. It is hoped that these findings will aid future efforts towards the rational design of novel cryoprotectants.

Diagnosis —Shells are conical with an overall oval outline, with or without inclined sides, topped by a centrally-placed apex wholly absorbed by an oval foramen in mature specimens. The foramen is bordered inside by a ring of callus that is not truncated or excavated posteriorly. Sculpture is chiefly radial.
Type species — Fissurella nimbosa Linnaeus (1758), by monotypy.
Remarks —The difference between Fissurella and the closely related genus Diodora is in the shape of the foramen at the apex and from the interior. In Fissurella the foramen is oval, while in Diodora the posterior end of the foramen is truncated. The interior of the shell described here is not available so the genus determination is questioned.

Understanding accounting students' learning and its relation to academic achievement: Exploratory case study
Creators: name: Elijido-Ten, Evangeline
Publisher: name: Swinburne
Year: 2024

description: This exploratory study aims to understand and uncover the contextual factors influencing accounting students' learning conception and approach and how it relates to their academic achievement. Three students who achieved different levels of overall mark (High Distinction, Credit and Pass) were interviewed and was taken as a case study to identify and analyse their learning conception and approach. The findings suggest that the way students approach and perceive their learning experience may not always tantamount to an excellent overall mark. Further investigation is needed to understand how other contextual factors may affect student learning. Some of the factors identified by the respondents associated to 'surface' learning are time constraint, poor organisation, work and family commitment and the assessment structure. It appears that putting too much emphasis on the end of semester examination encourage students to defer learning until the assessment is fast approaching. On the other hand, the factors associated with 'deep' learning are: personal habit and/or previous experience, personal commitment to improve, perceived relevance to career, peer pressure and pressure to achieve good grades.

description: This thesis, comprising two studies, investigated whether negative expectations and self-perceptions relating to the aging process are associated with less physical activity (Study 1), and whether less active adults are likely to report age as a cause for physical activity failure than more active adults (Study 2). Using Sarkisian et al.’s (2002) Expectations Regarding Aging (ERA-38) survey, Study 1 first developed reliable and valid sub-factors for constructs relating to general aging expectations (GAE) and aging self-perceptions (ASP) by conducting exploratory factor analyses on 167 adults (M age = 59.5). Results revealed three acceptable GAE sub-factors relating to satisfaction/contentment, physical function and cognitive function, and three ASP sub-factors pertaining to functional, social, and sexual health. Subsequent MANOVA analyses showed that active adults reported higher GAE for satisfaction/contentment and cognitive function than less active adults. Regression analyses revealed that physical activity levels positively predicted satisfaction/contentment and physical function expectations among 45-54 yr olds. In Study 2, 177 adults (M age = 60.1) completed our Causal Dimension Scale for Aging (CDSA) and a survey asking whether age was a likely cause of failure in various physical activity contexts. Responses on the CDSA were used to validate ‘General Attributions towards Age’ (GATA), a measure which captured how adults view the aging effects. Subsequent analyses of variance determined that GATA interacted with physical activity status (active, less active) to influence the reported likelihood of age as a cause for failure. Less active adults with stable/uncontrollable GATA reported greater likelihood of age as a cause for failure than all other groups in gym, recreational/community program, and unstructured/spontaneous activity settings. Separate age group analyses indicated that these trends were pronounced in an unstructured/spontaneous activity setting for 45-54 yr olds, and in a generally recently inactive scenario for 55-64 yrs.

description: The state-of-the-art industrial fabrication of silicon solar cells requires significant handling of wet processes and large amounts of wet chemicals. On the other hand, dry etching processes mostly require plasma and vacuum sources as well as use of process gases with high global warming potentials (GWP). In this work, an alternative plasma-free and mask-less dry etching technique of single-sided in nature is investigated. This novel dry etch process uses fluorine (F2), a low to zero GWP gas as etchant, diluted at atmospheric pressure condition to facilitate nanoscale texture of monocrystalline silicon (mono-Si). The etched surface morphology is optimized in terms of surface roughness or enlargement and surface reflection followed by the optimization of phosphorus oxychloride (POCl3) based n-type emitter diffusion and front surface passivation. Such optimization enables improved emitter homogeneity with minimum standard deviation of 3% and front passivation with just silicon nitride (SiNx) by plasma-enhanced chemical vapor deposition. Altogether this optimized nanotexture-emitter combination is integrated into the inline fabrication of the passivated emitter and rear solar cell or PERC-architecture allowing improved energy conversion and increased cell efficiency up to an absolute 0.6%.

description: Social anxiety disorder (SAD) is one of the most common anxiety disorders and understanding its symptoms and risk factors is vital for developing treatments and prevention strategies. Atypical physiological responses have been observed in anxious individuals and their consequences present a human and economic burden. This dissertation includes two studies that explore the subjective and physiological responses to an acute stress in the context of treatment and risk factors for SAD. The goal of the first study was to examine whether cognitive behavioural group therapy (CBGT) and a mindfulness-based stress reduction (MBSR) program differentially influenced the subjective and physiological response to a speech task. Participants in the treatment groups performed two speech tasks, before and after treatment, while a healthy control group completed it only once. Results indicated significant differences for the subjective, but not the physiological measures of stress. Patients with SAD reported higher subjective anxiety than the healthy control group and these scores were significantly reduced following treatment. Greater improvements were noted in the CBGT group; nonetheless, the study did indicate promising results for MBSR. The second study aimed to explore the effects of behavioural inhibition (BI), parental bonding variables and their interaction on the subjective and physiological responses to a similar speech task in healthy children. BI was related to subjective anxiety in a predictive manner, but was generally unrelated to the physiological measures. Parental bonding variables were not related to any of the stress responses and no interaction between BI and parental bonding was observed. These studies contribute to the literature by demonstrating treatment differences and their subjective and physiological consequences on stress reactions and exploring the extent to which risk factors for SAD affect the stress response in healthy children.

description: Lithium-ion batteries are exposed to a variety of degradation effects which negatively impact their lifetime. Due to the small spatial scale of these effects and the electrochemical complexity of the batteries, experimental insights are limited. Thus, numerical simulations of physical models can yield valuable insights into the underlying processes, while also providing a supplementary tool for digital prototyping. In this thesis, a model of nonlinear partial differential equations is considered which describes the lithium-ion concentration and the electric potential within the spatially resolved microstructure of the battery. Furthermore, the model accounts for one of the major contributors to capacity fade: the solid electrolyte interphase (SEI). The thesis extends on a previous monolithic solver using a fully implicit finite volume formulation by investigating an alternative flux approximation scheme for the coupled transport inside the electrolyte and developing a novel semi-implicit solution scheme. This semi-implicit scheme addresses handling of the SEI model within the coupled formulation and shows a significant improvement in robustness and performance for the considered simulations.

description: Abstract Data visuals (scientific images) display and express various amounts and types of information, and, as the saying goes,“an image is worth 1,000 words.” Based on a review of two studies, a new estimation of how many words an image is actually worth was calculated in an attempt to quantify the complicated biological process of image perception. The result revealed that an image is actually worth more than 30,000 words. This new value estimation provides insight into the power of images. Given that figures, graphs, and data visualizations are types of images commonly used in research and publications, every produced figure is important and must be carefully considered during the publication process.

description: This thesis examines evolving trends within public administration which have spurred the rise of privatized services in areas of governance traditionally provided by governments. One such area of governance in the United States has been the nation’s criminal justice system, specifically, the privatization of correctional facilities. Given what many would argue is an axiomatically different, profit-maximizing, goal-orientation among private sector actors from their public counterparts, many are questioning what impacts this could have on the dispersal of services within prisons, and specifically, the observed rates of recidivism once inmates are brought back into life outside of the institution. In assessing this development, the fields of New Public Management, Alternative Service Delivery, and Public-Private Partnerships are considered. The paper then conducts an historical review on the use, and prevalence, of privatized correctional facilities in the United States, including considerations of economic and academic debates. In assessing the academic debates, it is found that research on the use of private prisons and their relationship to recidivism rates have provided mixed results. It is also illustrated that the studies employ a variety of methodological differences. This paper seeks to understand whether the methodological differences between the studies have impacted the outcomes of the studies’ results. This is realized through a meta-analysis of existing studies in the field using statistical tools. In concluding, measurement and methodological considerations are found to have impacts on the results of the researchers’ studies.

description: Impulsive differential equations are useful for modelling certain biological events. We present three biological applications showing the use of impulsive differential equations in real-world problems. We also look at the effects of stability on a reduced two-dimensional impulsive HIV system. The first application is a system describing HIV induction-maintenance therapy, which shows how the solution to an impulsive system is used in order to find biological results (adherence, etc). A second application is an HIV system describing the interaction between T-cells, virus and drugs. Stability of the system is determined for a fixed drug level in three specific regions: low, intermediate and high drug levels. Numerical simulations show the effects of varying drug levels on the stability of a system by including an impulse. We reduce these two models to a two-dimensional impulsive model. We show analytically the existence and uniqueness of T-periodic solutions, and show how stability changes when varying the immune response rate, the impulses and a certain nonlinear infection term. The third application shows how seasonal changes can be incorporated into an impulsive differential system of Rift Valley Fever, and looks at how stability may differ when impulses are included. The analysis of impulsive differential systems is crucial in developing more realistic mathematical models for infectious diseases.

description: Die begrenzten Testkapazitäten in Speziallaboren stellen einen limitierenden Faktor in der Bekämpfung einer Pandemie dar. Kann der Einsatz von Biosensoren dabei helfen, diese Kapazitäten zu vergrößern? Ein Lab-on-chip Ansatz wurde untersucht, der sowohl Quantifizierung von Nukleinsäure-Amplifizierung, als auch Schmelzkurvenanalyse von Amplifikaten ermöglicht. Dabei wurde die Methode der Schleifen-vermittelten, isothermalen Amplifizierung (LAMP) betrachtet. Es konnte gezeigt werden, dass der Prozess der Synthetisierung und der Denaturierung von Nukleinsäure mithilfe der Biosensoren gemessen werden kann. Die Integration geeigneter Komponenten im Biosensor erlaubt die Durchführung der benötigten Temperaturprofile für beide Prozesse. Die vorgestellte Methode beschreibt ein Lab-on-Chip-System für den Einsatz der Datenerhebung von quantifizierter LAMP und angehängter Schmelzkurvenanalyse und legt den Grundstein für ein miniaturisiertes und valides Point-of-care Nukleinsäure-Testinstrument. The capacity of centralized clinical diagnosis laboratories represents a significant limiting factor in the fight against a pandemic. Can these capacities be extended by the use of electrochemical biosensors? A lab-on-chip system was investigated that allows the execution a monitoring of nucleic acid amplification and melt curve analysis of the resulting products. Here in, the method of loop-mediated isothermal amplification (LAMP) was used. It is shown that the processes of synthetization and denaturation of cDNS can be measured by the applied biosensors. The integration of appropriate components inside the biosensor allows the conduction of the necessary thermal profiles for both processes. The presented method describes a lab-on-chip system for the application in quantitative LAMP and consecutive melt curve analysis and opens the way for the development of a miniaturized, high-valid point-of-care nucleic acid test device.

description: Die Stickstoffoxidbelastung in den Städten, insbesondere an verkehrsreichen Standorten, zählt zu den großen Herausforderungen in der Luftreinhaltung. Bei der Feinstaubproblematik konnte die Einführung der Umweltzone maßgeblich zur Belastungsminderung beitragen. Nunmehr ist eine Fortentwicklung der Umweltzone erforderlich, damit auch die NOx-Belastungen deutlich vermindert werden können. Deshalb sollten im Bundesrecht die Voraussetzungen geschaffen werden, damit Städte die blaue Plakette einführen können. Nicht nur aus Gründen des vorsorgenden Gesundheitsschutzes besteht erheblicher Handlungsbedarf, sondern auch, um ein Vertragsverletzungsverfahren wegen mangelnder Umsetzung der Luftqualitätsrichtlinie zu verhindern. Die Einführung der blauen Plakette wäre außerdem ein Signal an die Industrie, die Abgasreinigung und die Entwicklung emissionsarmer Fahrzeuge ernsthaft voranzubringen. Sie kann darüber hinaus einen wichtigen Schritt hin zu einer Verkehrswende darstellen, die neben dem Klima- und Gesundheitsschutz auch die Verbesserung der Lebensqualität in den Städten als Ziel verfolgen sollte.
