description: Eisenbahnrahmenbrücken erfahren intensive dynamische Beanspruchungen. Aufgrund der massigen Bauteilabmessungen und der teilweise großen Steifigkeits-unterschiede zwischen Platte und Widerlagerwand ist das dynamische System häu-fig nicht eindeutig identifizierbar. In diesem Beitrag werden die maßgebenden Ein-flussfaktoren der Boden-Bauwerk-Interaktion auf das dynamische Verhalten des gebetteten Rahmens identifiziert. Dabei zeigt sich die vertikale Widerlagerfrequenz als maßgebender Parameter für das schwingende System. In den Untersuchungen werden verschiedene Modellierungsansätze verglichen. Hierbei zeigte sich, dass die Variante eines räumlichen mono-frequenzabhängigen Substrukturmodells un-ter bestimmten Bedingungen ähnlich genaue Ergebnisse liefert, wie mit einem re-chenintensiven, hybriden FEM-BEM Ansatz ermittelt werden.
Rules and Similarity in the Development of Category Learning in Children and Infants

Subjects: Developmental and Educational Psychology

description: Abstract Most theorists agree that adults can learn and use categories that are both rule- and similarity-based. There is less agreement about the mechanisms involved or on the distinction between rules and similarity. We begin by reviewing two recent theoretical positions, that of Pothos (2005) and of Ashby & colleagues (Ashby et al., 1998; Ashby and O’Brien, 2005). Identifying the notion of a rule to be the most problematic concept, we continue with a broader survey of rules in cognition. We propose that a developmental perspective could provide insight into these prob- lems. We review the existing literature from infancy and early childhood to show that previous studies have only tangentially investigated rules and similarity. We adapt and extend existing methods and present novel procedures and analyses that allow us to focus on a range of questions; When do rules emerge? What form do early rules take? Can statistical mechanisms give rise to rule-like performance? Is there a competition between rule and similarity processes? Four groups of experiments explore these questions. One set of experiments looks at 5-month-olds’ (and adults’) performance on several artificial grammar tasks devel- oped from Kirkham et al. (2002). We demonstrate that participants are sensitive to the complexity of certain sequence structures. Another pair of tasks investigate infants’ learning of abstract Same-Different relations. We find that 8-month-olds will learn the relation in both an habituation and an anticipation task, whereas 4-month-olds only succeed on the latter. A third group of tasks juxtapose unidi- mensional and family resemblance categorization using both rich and impoverished stimuli. We find that infants form flexible classifications. Finally, we present a set of computer games for young children that explore these questions in a more ecologically valid setting than traditional laboratory classification tasks.

description: Electron pulse trains with sub-femtosecond spike length offer novel possibilities to ultra-fast pump-probe experiments in free-electron lasers. The pulse train can be generated by an energy modulation which is converted to temporal bunching in a magnetic chicane. The source of the energy modulation is typically a resonant interaction with a co-propagating laser in a wiggler magnet. Alternatively, the modulation can be obtained by a dielectric laser accelerator (DLA). The implementation of the DLA modulation scheme at SwissFEL would be enabled by using the experimental chamber installed in the framework of the Accelerator-on-a-Chip International Program (ACHIP) and a magnetic chicane placed afterwards. In this contribution, we will focus on electron beam diagnostics for the DLA-modulated and compressed electron bunch train. Our simulation results predict that measuring the energy spread of the modulated beam and coherent diffraction radiation emitted from a foil with a hole provides a precise tool to characterize and optimize the laser-electron modulation. An absolute measurement of the longitudinal phase-space with a temporal rms-resolution of 350 as is possible with the planned X-band transverse deflecting cavity in Athos.
The tools of a cartographic poet: unmapping settler colonialism in Joy Harjo's poetry
Creators: name: Goeman, Mishuana
Publisher: name: Swinburne
Year: 2024

description: This essay looks at alternatives to the Cartesian forms of mapping that have come to structure settler colonial geographies. The poetry of Joy Harjo enables an engagement with concepts of spatial justice from an Indigenous feminist practice. I place Harjo's poetry into multiple conversations with various tribal stories and geographies, thus illuminating constellations of human relationships to each other and to land and their complexity. Settler colonialism is about putting into place settler understanding of geography. These are always gendered practices. Language and concepts of storied land enable us to push for a spatial justice that unpacks settler produced knowledges. It is this type of focus on land that engenders my desire to (re)map socialities that will materially and mentally sustain future Indigenous generations.

description: This thesis examines the extent to which the development of expertise in diagnostic palpation in osteopathic medicine is associated with changes in cognitive processing. Chapter 2 and Chapter 3 review, respectively, the literature on the role of analytical and non-analytical processing in osteopathic and medical clinical decision making; and the relevant research on the use of vision and haptics and the development of expertise within the context of an osteopathic clinical examination. The two studies reported in Chapter 4 examined the mental representation of knowledge and the role of analogical reasoning in osteopathic clinical decision making. The results reported there demonstrate that the development of expertise in osteopathic medicine is associated with the processes of knowledge encapsulation and script formation. The four studies reported in Chapters 5 and 6 investigate the way in which expert osteopaths use their visual and haptic systems in the diagnosis of somatic dysfunction. The results suggest that ongoing clinical practice enables osteopaths to combine visual and haptic sensory signals in a more efficient manner. Such visuo-haptic sensory integration is likely to be facilitated by top-down processing associated with visual, tactile, and kinaesthetic mental imagery. Taken together, the results of the six studies reported in this thesis indicate that the development of expertise in diagnostic palpation in osteopathic medicine is associated with changes in cognitive processing. Whereas the experts’ diagnostic judgments are heavily influenced by top-down, non-analytical processing; students rely, primarily, on bottom-up sensory processing from vision and haptics. Ongoing training and clinical practice are likely to lead to changes in the clinician’s neurocognitive architecture. This thesis proposes an original model of expertise in diagnostic palpation which has implications for osteopathic education. Students and clinicians should be encouraged to appraise the reliability of different sensory cues in the context of clinical examination, combine sensory data from different channels, and consider using both analytical and non-analytical reasoning in their decision making. Importantly, they should develop their skills of criticality and their ability to reflect on, and analyse their practice experiences in and on action.

description: The nutrient and pesticide abatement efficiency of varying mixtures was examined in a vegetated free water surface constructed wetland. Three different agricultural chemical pollutant mixture conditions were assessed: nutrients only (N and P); pesticides only (atrazine, S-metolachlor and permethrin); and a mixture of nutrients and pesticides. With nutrients only, 672 h nutrient mitigation of 77–91% total phosphorous (TP) and 74–98% total nitrogen (TN) was associated with distance from the injection point and rainfall, whereas with nutrient and pesticide mixtures, 672 h nutrient mitigation of 11–71% TP and 84–98% TN were associated with distance and time. With pesticides only, 672 h pesticide mitigation of 50–99% was associated with distance and time, whereas with nutrients and pesticide mixtures, 672 h pesticide mitigation of 48–99% was associated primarily with distance. Dissipation half-lives were 2–10 times greater for P and 1.5–5 times greater for N when pesticides were present. Pesticide dissipation half-lives showed no clear differences with or without nutrients. While vegetated free water surface constructed wetlands can be effective best management practice tools to trap and abate agricultural run-off during rainfall events, efficiencies can be affected by different types of complex pollutant mixtures and wetland design and implementation should accommodate varying efficiencies.
Cross Boarder Interference on UMTS Mobile Network and Its Impact on Revenue: the Case of Border Town Togowchale

Year: 2018

description: Universal Mobile Telecommunications System (UMTS) which has been standardized by the 3rd Generation partnership project (3GPP) organization, utilizes Wideband Code Division Multiple Access (WCDMA) as radio access technology. UMTS are designed to meet the increasing demands for high data rate applications and greater mobility. High data rate applications include voice, video telephony, Video streaming, File Transfer protocol (FTP), high quality image and wireless internet access. But there are many factors like loading of cell, interference etc. that limits to access these high data rate services or limits the capacity of the systems. The uplink channel is, by nature, an interference-constrained multiple-access channel. Cross border interference is caused due to the usage of the same set frequencies between two adjacent boundaries of different operators. This is the case where other operator locates their base stations in close proximity in order to provide comparable coverage to their customers. This thesis attempts to identify cross boarder interference, analysis to its impacts to the uplink capacity of all service in UMTS systems and loss of revenues is presented. The work starts with UMTS overview and learn some important concept about UMTS uplink channel interference. Then go deep into uplink channel capacity and apply the two load analysis methods to estimate the capacity loss. In the end revenue is calculated using the tariff incurred for each types of service. Ethio telecom can use this research to gain a better understanding of the problem in order to plan a strategy required to be profitable. The results described in this thesis will be a valuable contribution towards the awareness of how interference of another operator's network (which we can' t control) affects the performance of the network elements at boarder town.

Empirical Outdoor-to-Indoor Propagation Path Loss Models Investigation and Tuning for 900, 1800 & 2100 MHz Frequencies: the Case of Addis Ababa City
Creators: name: Zerihun, Teshome
Publisher: name: National Academic Digital Repository of Ethiopia

description: As trend of cellular traffic shifts from voice dominant to data and most of this traffic is being generated from indoor environment, providing optimal indoor solutions is becoming prime target of a radio planning task. But, it is a challenging task to meet the radio signal coverage target that ensures signal quality required by data traffic in indoor environment as radio propagation is impacted by building penetration loss (BPL) and in building propagation path loss. Hence, to ensure radio signal coverage target in such environment it is required to closely investigate and characterize these two losses. Investigating and characterizing these losses is prominently important for vertically expanding cities like Addis Ababa, Ethiopia, where outdoor macro sites are predominant solution to avail indoor environment signal coverage targets. This thesis aims to accomplish this critical task for city of Addis Ababa. Representative sample buildings based on morphology, purpose, building material types and building to transmitter antenna height relation are selected. Moreover, commonly used indoor propagation models are identified. Measurement is undertaken, based on measurement it is attempted to estimate BPL and tuned model parameters for the selected propagation models for various categories of indoor environments to determine unified outdoor-to-indoor propagation model. The results indicate that for a frequency of 900MHz, BPL for buildings made from hollow concrete blocks/bricks is identified as 12.01dB to 17.7dB; for building made from stone masonry the value ranges from 15.11dB to 17.81dB; and from 2.46dB to 8.81dB for buildings mainly made from glass. For 1800MHz frequency the identified BPL results are: 13.7dB to 17.51dB for buildings made from hollow concrete blocks/bricks; 16.38dB to 25.41dB for buildings made from stone masonry; and 0.89dB to 8.14dB for buildings mainly made from glass. Similarly, BPL for 2100MHz frequency is identified as 12.22dB to 13.36dB for buildings made from hollow concrete blocks/bricks; 14.16dB to 19..66dB for buildings made from stone masonry; and 6.25dB to 10.36dB for buildings mainly made from glass. Then, for the measured indoor path loss, parameters of the Path Loss Slope (PLS) model were tuned to capture radio signal propagation characteristics in the indoor environments. The results indicate that, the path loss exponent is found out to be in the range of 0.52 to 2.09 depending on the indoor environment considered. To validate the models, Root Mean Square Error (RMSE) is computed and it is found out it ranges from 1.06dB to 5.25dB depending on different building environments and selected models. The resulting outdoor-to-indoor propagation models can be used for coverage planning in the city of Addis Ababa.

description: Resumo A guerra civil é a forma de violência coletiva mais importante de nossa época. Embora pesquisas recentes tenham apontado alguns elementos como determinantes das guerras civis,a influência dos fatores políticos nos conflitos internos ainda é controversa. O presente estudo analisa, por meio de regressão estatística, a relação entre a competitividade do poder executivo e a incidência de guerras civis de 1976 a 2000. Os achados indicam que tanto eleições com candidatos únicos como votações multipartidárias reduzem a incidência de guerras civis. Ademais, os resultados dão apoio às hipóteses levantadas pela literatura recente de que terreno montanhoso, grande população, sistema políticos centralizados e a existência de conflitos anteriores aumentam significativamente o risco de incidência de guerras civis. Palavras-chave: guerras civis, poder executivo, regimes políticos, eleições Abstract Civil War is the most important form of collective violence of our time. Although recent research has yielded some determining elements to civil war, the influence of political factors on internal conflicts remains disputed. This study analyzes, by means of statistics regression, the correlation between the competitiveness in the Executive Branch and the incidence of civil war from 1976 to 2000. The findings indicate that both single-candidate and multi-party elections reduce the incidence of civil war. Furthermore, the results lend support to the hypotheses put forward by recent literature that mountainous terrain, large population, centralized political system, and the existence of former conflicts significantly heighten the risk of incidence of civil war.

Root Cause Analysis of Base Station Outage using Bayesian Network for Addis Ababa
Creators: name: Tesfaye, Fetene
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2020

description: For telecom operators, base station is one of the most important mobile network component from which messages are sent and received directly to/from users. The base station consists of different hardware and software components. Any of these components could experience various types of faults (critical, major and minor) that may cause partial or full failure of the base station until correction is made. Base station outage results in its users' service interruption or quality degradation that in turn brings to the operator churn of users/services and loss of revenue. Therefore, outage is needed to be monitor and its cause should be identified timely for timely maintenance actions. To reduce maintenance time and cost, different advanced outage root cause analysis methods have been studied and applied. However, there are limited studies in the context of Ethiopia. The objective of this thesis is to present root cause analysis of base station outage for Addis Ababa using Bayesian network empowered by trouble ticket, log file, and history alarm. Results show that application of root causes analysis can be achieved to identify, categorize and define appropriate supportive action for base station outage. By analyzing, the base station outage based on collected history alarm, log file and trouble ticket data can compute probability distribution and provide a priority checking. For instance, the result from historical data collected for year shows that the performance of Bayesian network with an accuracy of 94%.

description: A number of techniques are used for testing the anti-biofouling activity of surfaces, yet the correlation between different results is often questionable. In this report, the correlation between initial bacterial deposition (fast tests, reported previously) and biofilm growth (much slower tests) was analyzed on a pristine and a surface-modified reverse osmosis membrane ESPA-1. The membrane was modified with grafted hydrophilic polymers bearing negatively charged, positively charged and zwitter-ionic moieties. Using three different bacterial strains it was found that there was no general correlation between the initial bacterial deposition rates and biofilm growth on surfaces, the reasons being different for each modified surface. For the negatively charged surface the slowest deposition due to the charge repulsion was eventually succeeded by the largest biofilm growth, probably due to secretion of extracellular polymeric substances (EPS) that mediated a strong attachment. For the positively charged surface, short-term charge attraction by quaternary amine groups led to the fastest deposition, but could be eventually overridden by their antimicrobial activity, resulting in non-consistent results where in some cases a lower biofilm formation rate was observed. The results indicate that initial deposition rates have to be used and interpreted with great care, when used for assessing the anti-biofouling activity of surfaces. However, for a weakly interacting ‘low-fouling’ zwitter-ionic surface, the positive correlation between initial cell deposition and biofilm growth, especially under flow, suggests that for this type of coating initial deposition tests may be fairly indicative of anti-biofouling potential.

description: Cloud Computing (CC) is being accepted as one of the emerging technologies that create a new opportunity for enterprises with limited resources. It is promised that cloud can allow firms to reduce costs and to operate more flexibly than with a traditional Information Technology (IT) infrastructure. However, the promising opportunities go hand-in-hand with several challenges that can pose risks for a firm planning to adopt CC. A number of frameworks and models have been developed by prior studies to support cloud adoption process. However, these models and frameworks have been formulated to the context of developed countries. Though worldwide research may be applicable to at least some extent research regarding the adoption of cloud is not fully generalizable to corporate environment. In this study, we have proposed a conceptual cloud adoption model grounded by Technology Organization and Environment (TOE) and Diffusion of Innovation (DOI) frameworks. According to this model, six variables are influencing the Small and Medium Enterprises (SMEs)' decision to adopt CC. To test the proposed model, we have used dataset collected from 136 SMEs and analyzed using Multiple Linear Regression (MLR). The analysis revealed that the model is statistically significant [F (6,129) 73.631 and p <0.001]. Four out of the six determinants were found to be significant for their influence of cloud adoption. Moreover, a Cloud Deployment Selection Model (CDSM) has been also proposed to support SMEs' in predicting an appropriate cloud model for their business need. The model is generated by refining the MLR output and using the established principles of Analytic Hierarchy Process (AHP).

description: In this study, a hydroponics experiment was conducted to investigate the characteristics of Cd tolerance and accumulation of Elsholtzia argyi natively growing on the soil with high levels of heavy metals in a Zn/Pb mining site. Seedlings of E. argyi grown for 4 weeks and then were treated with 0(CK), 5, 10, 15, 20, 25, 30, 40, 50, 100 μM Cd for 21days. Each treatment had three replications. No visual toxic symptoms on shoots of E. argyi were observed at Cd level ≤50 μM. The results indicated that the dry biomass of each tissue and the whole plants of the treatments with ≤40 μM cadmium were similar to that of the control, implying that E. argyi was a cadmium tolerant plant. The results also showed that the shoot Cd concentration significantly (P < 0.05) increased with the increase in the Cd level in nutrient solution. The shoot Cd concentration of the treatment with 40 μM Cd was as high as 237.9 mg kg–1, which was higher than 100 mg kg–1, normally used as the threshold concentration for identifying the Cd hyperaccumulating plant. It could be concluded that E. argyi was a Cd tolerant and accumulating plant species.

description: The Arafura and Timor Seas (ATS) comprise both near pristine and highly threatened marine ecosystems. There are four littoral nations (Indonesia, Timor-Leste, Australia, and Papua New Guinea), which have independently established Marine Protected Areas (MPAs). We design the first resilient MPA network for the entire region to protect critical habitats and species by considering transboundary features (i.e., connectivity of fisheries, rare, threatened, and protected species), uses and threats (i.e., fishing and climate change). We used Geographic Information System processing to identify gaps in the regional network based on existing and proposed MPAs and Areas of Interest (AOIs: previously identified as potential new MPAs) in each country, followed by systematic conservation planning to identify new AOIs for establishing MPAs to fill these gaps. The ATS MPA Network design (301,055 km2) has been endorsed by all four countries and includes all 93 existing (265,405 km2) and proposed (6,264 km2) MPAs, 13 previously identified AOIs (14,773 km2), and seven new AOIs identified in this study (14,613 km2). Of the new AOIs, three have been incorporated in Indonesia’s national MPA network plan, one is in a new MPA currently being developed in Timor-Leste, and Australia is considering two as potential areas for new MPAs.

description: Nanoparticles (NPs) contained in commercial products are released and enter into the aquatic ecosystem, posing serious possible risks to the environment and affecting the food chain. Therefore, investigating the potential toxicity of NPs on aquatic organisms has become an important issue. This study assessed the toxicity and trophic transfer of metal oxide NPs from marine microalgae (Cricosphaera elongata) to the larvae of the sea urchin Paracentrotus lividus. Larvae (24 h old) were fed on 2000 cell mL−1 48 h of microalgae contaminated with 5 mg L−1 of several metal oxide NPs (SiO2, SnO2, CeO2, Fe3O4) for 15 days. Larval viability and development were monitored from the 4-arm stage to the 8-arm pluteus stage. A significant decrease in survival was observed in larvae fed with microalgae exposed to SiO2 and CeO2 NPs. Abnormal development, characterised by skeletal degeneration and altered rudiment growth, was observed in all larvae fed with contaminated NP algae. Our findings revealed that SiO2 and CeO2 NPs exerted a toxic effect in the trophic interaction analysed, by reducing sea urchin larval viability, and all metal oxide NPs induced toxicological effects. In conclusion, metal oxide NPs may enter the food chain and become bioavailable for marine organisms, affecting their development.

description: The use of an abundant and widely distributed seagrass species, Posidonia oceanica, as a biosorbent for the direct dye Yellow 44 was successfully shown. The studies were performed on the single dyestuff dissolved in water and in a dyebath containing agents commonly used in the textile industry, i.e. a surfactant (Lavotan TBU), a sequestring agent (Meropan DPE), a softening agent (Eurosoft CI10) and a salt (NaCl). The colour reduction results showed that P. oceanica was found to be more efficient for removal of Yellow 44 from an aqueous solution (162 mg g−1) than from a dyebath solution (135 mg g−1), according to the Langmuir isotherm model. For the single dyestuff sorption, Fourier transform infrared and X-ray photoelectron spectroscopy studies highlighted chemical sorption between the dye alcohol function and the sorbent acid function. The chemical oxygen demand removal percentages were found to be 54.9 and 76.6% for Yellow 44 dissolved in aqueous solution and in dyebath solution, respectively. This confirmed the both sorption of the chemical auxiliaries and the dye on P. oceanica.

description: Surface-active polymers derived from styrene monomers containing siloxane (S), fluoroalkyl (F) and/or ethoxylated (E) side chains were blended with an elastomer matrix, either poly(dimethyl siloxane) (PDMS) or poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS), and spray-coated on top of PDMS or SEBS preformed films. By contact angle and X-ray photoelectron spectroscopy measurements, it was found that the surface-active polymer preferentially populated the outermost layers of the coating, despite its low content in the blend. However, the self-segregation process and the response to the external environment strongly depended on both the chemistry of the polymer and the type of matrix used for the blend. Additionally, mechanical testing showed that the elastic modulus of SEBS-based coatings was one order of magnitude higher than that of the corresponding PDMS-based coatings. The coatings were subjected to laboratory bioassays with the marine alga Ulva linza. PDMS-based coatings had superior fouling-release properties compared to the SEBS-based coatings.

description: In this study, a hydroponics experiment was conducted to investigate the characteristics of Cd tolerance and accumulation of Elsholtzia argyi natively growing on the soil with high levels of heavy metals in a Zn/Pb mining site. Seedlings of E. argyi grown for 4 weeks and then were treated with 0(CK), 5, 10, 15, 20, 25, 30, 40, 50, 100 μM Cd for 21days. Each treatment had three replications. No visual toxic symptoms on shoots of E. argyi were observed at Cd level ≤50 μM. The results indicated that the dry biomass of each tissue and the whole plants of the treatments with ≤40 μM cadmium were similar to that of the control, implying that E. argyi was a cadmium tolerant plant. The results also showed that the shoot Cd concentration significantly (P < 0.05) increased with the increase in the Cd level in nutrient solution. The shoot Cd concentration of the treatment with 40 μM Cd was as high as 237.9 mg kg–1, which was higher than 100 mg kg–1, normally used as the threshold concentration for identifying the Cd hyperaccumulating plant. It could be concluded that E. argyi was a Cd tolerant and accumulating plant species.

description: Nanoparticles (NPs) contained in commercial products are released and enter into the aquatic ecosystem, posing serious possible risks to the environment and affecting the food chain. Therefore, investigating the potential toxicity of NPs on aquatic organisms has become an important issue. This study assessed the toxicity and trophic transfer of metal oxide NPs from marine microalgae (Cricosphaera elongata) to the larvae of the sea urchin Paracentrotus lividus. Larvae (24 h old) were fed on 2000 cell mL−1 48 h of microalgae contaminated with 5 mg L−1 of several metal oxide NPs (SiO2, SnO2, CeO2, Fe3O4) for 15 days. Larval viability and development were monitored from the 4-arm stage to the 8-arm pluteus stage. A significant decrease in survival was observed in larvae fed with microalgae exposed to SiO2 and CeO2 NPs. Abnormal development, characterised by skeletal degeneration and altered rudiment growth, was observed in all larvae fed with contaminated NP algae. Our findings revealed that SiO2 and CeO2 NPs exerted a toxic effect in the trophic interaction analysed, by reducing sea urchin larval viability, and all metal oxide NPs induced toxicological effects. In conclusion, metal oxide NPs may enter the food chain and become bioavailable for marine organisms, affecting their development.

description: The nutrient and pesticide abatement efficiency of varying mixtures was examined in a vegetated free water surface constructed wetland. Three different agricultural chemical pollutant mixture conditions were assessed: nutrients only (N and P); pesticides only (atrazine, S-metolachlor and permethrin); and a mixture of nutrients and pesticides. With nutrients only, 672 h nutrient mitigation of 77–91% total phosphorous (TP) and 74–98% total nitrogen (TN) was associated with distance from the injection point and rainfall, whereas with nutrient and pesticide mixtures, 672 h nutrient mitigation of 11–71% TP and 84–98% TN were associated with distance and time. With pesticides only, 672 h pesticide mitigation of 50–99% was associated with distance and time, whereas with nutrients and pesticide mixtures, 672 h pesticide mitigation of 48–99% was associated primarily with distance. Dissipation half-lives were 2–10 times greater for P and 1.5–5 times greater for N when pesticides were present. Pesticide dissipation half-lives showed no clear differences with or without nutrients. While vegetated free water surface constructed wetlands can be effective best management practice tools to trap and abate agricultural run-off during rainfall events, efficiencies can be affected by different types of complex pollutant mixtures and wetland design and implementation should accommodate varying efficiencies.
The Orang Ulu and the museum: investigating traces of collaboration and agency in ethnographic photographs from the Sarawak Museum in Malaysia
Creators: name: Horn, Christine
Publisher: name: Swinburne
Year: 2024

description: The Sarawak Museum archive in Malaysia contains thousands of photographic prints and negatives from the region. From the early 1950s onwards, museum staff documented their work in Indigenous communities by taking photographs of people, traditional practices, material artifacts and environments. Such colonial photographs have been criticized for their role in establishing cultural stereotypes and supporting the political frameworks of domination that enabled their production. My thesis examines how their institutional origins affected the ways in which people in the source communities interpreted the photographs. The research involved returning 1500 photographs from the archive to Orang Ulu communities in northern Sarawak.

description: In contrast to the national-level policies found in most developed nations, in the USA, sub-national governments have emerged as leaders in formulating climate change policy. Yet participation is uneven, and little is understood about why some act and others do not. This paper examines two sets of factors for their influence on climate change adaptation planning in communities of the Great Plains. Using survey data collected from a range of natural resources managers in 900+ jurisdictions in 12 states, the study examines the impact of perceived barriers to climate change planning and the natural environment on the probability that jurisdictions will engage in adaptation planning. The findings show that most jurisdictions remain sceptical of climate change and see no need to engage in adaptation planning. Among those that have begun to plan or have a plan in place already, the strongest influence comes from changes in the physical environment itself.

description: The use of an abundant and widely distributed seagrass species, Posidonia oceanica, as a biosorbent for the direct dye Yellow 44 was successfully shown. The studies were performed on the single dyestuff dissolved in water and in a dyebath containing agents commonly used in the textile industry, i.e. a surfactant (Lavotan TBU), a sequestring agent (Meropan DPE), a softening agent (Eurosoft CI10) and a salt (NaCl). The colour reduction results showed that P. oceanica was found to be more efficient for removal of Yellow 44 from an aqueous solution (162 mg g−1) than from a dyebath solution (135 mg g−1), according to the Langmuir isotherm model. For the single dyestuff sorption, Fourier transform infrared and X-ray photoelectron spectroscopy studies highlighted chemical sorption between the dye alcohol function and the sorbent acid function. The chemical oxygen demand removal percentages were found to be 54.9 and 76.6% for Yellow 44 dissolved in aqueous solution and in dyebath solution, respectively. This confirmed the both sorption of the chemical auxiliaries and the dye on P. oceanica.

description: The ‘sustainable remediation’ concept has been broadly embraced by industry and governments in recent years in both the US and Europe. However, there is a strong need for more research to enhance its ‘practicability’. In an attempt to fill this research gap, this study developed a generalised framework for selecting the most environmentally sustainable remedial technology under various site conditions. Four remediation technologies were evaluated: pump and treat (P&T), enhanced in situ bioremediation (EIB), permeable reactive barrier (PRB), and in situ chemical reduction (ISCR). Within the developed framework and examined site condition ranges, our results indicate that site characteristics have a profound effect on the life cycle impact of various remedial alternatives, thus providing insights and valuable information for determining what is considered the most desired remedy from an environmental sustainability perspective.
Media and migration: a review of the field

Publisher: name: Swinburne

description: The interrelationships between media and migration is not a new field of study, but it is a rapidly growing and not unproblematic one. The migration process itself generates a reliance on mediated forms of communication. Yet, while, traditionally, public service broadcasting has addressed an audience that was imagined on the national scale, society in immigration countries is becoming increasingly heterogeneous. At the same time, massive advances in the technology of communication have opened up transnational communication channels of a speed, scale, and level of accessibility never seen before. Technological advances, changes in regulatory regimes, and increasing audience demand are also fundamentally transforming the patterns of production, distribution, and consumption of media content. This paper examines how these three processes are combining to drive change in global media and communications patterns, and considers the implications for such changes on the democratic ideal of the public sphere.
