Evaluation

description: Introduction: An injury surveillance system was piloted in 2011 to monitor injuries in Canadian Forces. This evaluation of the key system attributes examined system performance. Methods: A retrospective chart review, a coding reliability study, a completeness of forms study and a key informant interview. Results: Sensitivity was 0.36 (95% CI: 0.28, 0.46). The system was missing patients over age 35. Kappa coefficients over 0.80 demonstrated good agreement. Completeness of forms study demonstrated high percentages of response for most questions and lower rates for questions related to using protective equipment, and consent for information sharing. Interviews proved acceptability to stakeholders, usefulness for identifying clusters and trends, simple and complete data collection, and flexibility. Conclusion: The injury surveillance system had good potential for several reasons: data collection did not require additional work in clinics; the system was well accepted and partially proved usefulness and timeliness in identifying unusual injury events.
Self-Serving Biases In Students' Evaluations of Teaching: Examining the Impact of Self-Reported Narcissism and Shyness

description: Students’ evaluations of teaching (SETs) have been used as a primary means of evaluating the teaching quality at postsecondary institutions for a number of years. The research in this area has been consistently expanding in an effort to validate its use and efficacy. To date, there has been little consensus regarding the validity of these evaluations, especially with regards to the possible impact of extraneous factors. Researchers have previously found evidence of a link between the self-serving bias and grade expectations. The present study used an experimental design to examine the validity of SETs in the context of the self-serving bias. According to the self-serving bias, individuals will be more likely to attribute success internally but attribute failure externally. Specifically, the present study examined whether there were differences in the presence of the self-serving bias in relation to self-reported narcissism and shyness. Students at a large university aged 17 - 46 (N = 563) were asked to write a short essay on euthanasia and were randomly assigned to one of two conditions. In the first condition, students were assigned a low grade; in the second condition, they were assigned a high grade. When they were given their essay grade back, students had an opportunity to rate their evaluator. Results indicated that students were more likely to externalize their essay grade when in the negative condition whereby they attributed their grade to reasons outside their control versus the positive condition, irrespective of their level of self-reported narcissism or shyness. These results suggest that the self-serving bias does exist within SETs and calls into question the validity of these evaluations. The findings from this study highlight the need for further research into the role that student characteristics play with regards to SETs.

description: The influence of electronic percussion (in particular, the Simmons Drum Company’s innovations) on the compositions and evolution of 1980s Pop music can be examined through technological advancements as well as stylistic characteristics of drum partitions of the decade. Archived company catalogues in collaboration with Matt Dean’s historical timeline provide a clear understanding of the advancements during the time of the company’s tenure at the top of the electronic percussion industry. Definitions of the terms “style” and “genre” in both the primary and secondary approaches -by Allan Moore and other theorists- are used. The stylistic properties which create a genre are key in understanding the political, social, and cultural effects on the music. Ultimately, stylistic traits provide sufficient evidence in order to examine similar compositions which were sub-categorized differently on Billboard’s hit charts. Dave Carlton’s Hook Theory is a major resource in selecting pieces of music which share similarities. The differences in sub-categorization identified in this study are shown to derive from the transition to and the use of electronic percussion.
The 2007 Australian election: blue-collar voters, migrants and the environment
Creators: name: Betts, Katharine
Publisher: name: Swinburne

description: The 2007 Australian Election Study shows that many blue-collar voters, the so-called Howard battlers, returned to Labor. Combined with earlier surveys it also shows that non-English-speaking-background migrants have consistently been more likely to vote Labor than the Australia-born. They were particularly likely to do so in 2007, especially if they were in blue-collar occupations. The Howard Government’s Work Choices legislation probably played a role in these outcomes. However, the data also show that Labor’s environmental policy also played an important part. Thirty five per cent of voters were influenced by an environmental issue during the campaign, more than were affected by any other set of issues. Concern about the environment is spread across all occupational groups, though it is rather more pronounced among professionals.

description: Recently, our world witnessed major events that attracted a lot of attention towards the importance of automatic crowd scene analysis. For example, the COVID-19 breakout and public events require an automatic system to manage, count, secure, and track a crowd that shares the same area. However, analyzing crowd scenes is very challenging due to heavy occlusion, complex behaviors, and posture changes. This paper surveys deep learning-based methods for analyzing crowded scenes. The reviewed methods are categorized as (1) crowd counting and (2) crowd actions recognition. Moreover, crowd scene datasets are surveyed. In additional to the above surveys, this paper proposes an evaluation metric for crowd scene analysis methods. This metric estimates the difference between calculated crowed count and actual count in crowd scene videos.

description: Fluoxetine, a selective serotonin re-uptake inhibitor (SSRI) and the active ingredient in Prozac®, is found in the environment and disrupts feeding and metabolism in exposed fish. The objective of this research was to investigate the mechanisms involved in the feeding and metabolism disruption in the model goldfish (Carassius auratus). Two short-term waterborne fluoxetine exposures (7- and 14-days) were performed using two environmentally relevant doses of fluoxetine (0.5 and 1 μg/L) and metabolic effects at the level of the brain, liver, serum and bile in goldfish were investigated. Abundances of mRNA transcripts coding for six feeding neuropeptides were examined to determine which may be involved in the initial neural changes associated with decreased appetite in goldfish. The 7-day fluoxetine exposure at 1 μg/L caused corticotropin-releasing factor (CRF) mRNA levels to increase by 2-fold in female hypothalamus and telencephalon, indicating that CRF may be one of the first of the feeding neuropeptides to be altered. Six hepatic miRNAs were also evaluated in the goldfish liver that were previously associated with fluoxetine exposure in zebrafish (Danio rerio). Following the 7-day exposure at 1 μg/L, miR-22b, miR-140, miR-210, miR-301a and miR-457b levels increased in the female goldfish liver by 4-6 fold. The 14-day fluoxetine exposure at 1 μg/L caused 2-fold increases in miR-210, miR-301a, miR-457b and let-7d in male goldfish liver. These miRNAs were associated with the down-regulation of anabolic metabolic pathways in zebrafish, indicating a conservation of miRNA and fluoxetine effect between fish species. Serum and bile metabolite profiles of fluoxetine exposed goldfish were evaluated using ultra performance liquid chromatography coupled to quadrupole time of flight mass spectrometry. Following the 14-day exposure at 1 μg/L, the bile metabolite profiles of male goldfish were significantly different from controls as detected by cluster analysis and fluoxetine was tentatively identified in the serum. No other discriminant metabolites were identified as of yet. The data presented suggest that fluoxetine causes metabolic disruption in goldfish at multiple organ levels. Because of the widespread detection of fluoxetine and other emerging SSRIs in the aquatic environment, future research is required to firmly establish this pharmaceutical class as a metabolic and endocrine disrupting chemical.

Multilevel (random-intercept) logistic regression modelling

description: Innovativeness is one of the fundamental instruments of growth strategies that provide companies with a competitive edge. Only a few recent studies have examined marketing innovation and the factors that might encourage its adoption. This study investigates the factors that motivate marketing innovation and examines whether the occurrence of marketing innovation varies across industry sectors. This study uses data from surveys and a nationwide census conducted by Statistics Canada. They include: the Survey of Innovation and Business Strategies (SIBS) 2009, the Survey of Innovation and Business Strategies (SIBS) 2012, the Business Registry (BR) and the General Index of Financial Information (GIFI). Multilevel (random-intercept) logistic regression modelling is employed. The results show that if a firm has a strategic focus on new marketing practices, maintains marketing within its enterprise, acquires or expands marketing capacity, has competitor and customer orientations, and adopts advanced technology then it is more likely to carry out marketing innovation. However, breadth of long-term strategic objectives and competitive intensity do not have significant impacts on marketing innovation. In addition, product innovation and organizational innovation occur simultaneously with marketing innovation, but process innovation may not. Lastly, the occurrence of marketing innovation is found to vary across industry sectors. The theoretical and empirical implications of the results are discussed within this study.

description: By analysing a selection of productivity reports from four different countries (New Zealand, Australia, the United Kingdom and Canada) over a ten year period (2000-2009), we map the discursive representations of the concept “productivity” in order to gain insights into local strategies and global similarities in approaches to generating productive change. Using Leximancer we analysed five matched reports for each country, and argue that the reports contain a range of subtle and not-sosubtle nuances in the productivity discussions of each country. Despite this wide variation in local themes, we propose that the rhetorical strategies employed are evidence of significant mimetic isomorphism, driven by the uncertainty surrounding the notion of productivity.

description: This study evaluates the enhancement of anaerobic digestion (AD) of the organic fraction of municipal solid waste (OFMSW) by microwave pretreatment (MW) at high temperatures (115, 145 and 175°C). The highest level of solubilization was achieved at 175ºC, with a supplemental water addition of 30% (SWA30). Pretreatments combining two modalities; MW heating in presence or absence of hydrogen peroxide (H2O2) was also investigated. Biochemical methane potential (BMP) tests were conducted on the whole OFMSW, as well as on the liquid fractions. The whole OFMSW pretreated at 115 and 145 ºC showed little improvement in biogas production over control. When pretreated at 175 ºC, biogas production decreased due to formation of refractory compounds, inhibiting digestion. For the liquid fraction of OFMSW, the effect of pretreatment on the cumulative biogas production (CBP) was more pronounced for supplemental water addition of 20% (SWA20) at 145 ºC. Combining MW and H2O2 modalities did not have a positive impact on OFMSW stabilization and enhanced biogas production. Based on the BMP assay results, the effects of MW pretreatment (145 ºC) on the AD of OFMSW (SWA20) were further evaluated in single and dual stage semi-continuous digesters at hydraulic retention times (HRTs) of 20, 15, 12 and 9 days. Overall, MW pretreatment did not enhance the AD of the whole waste at the HRTs tested. However, the use of a dual stage reactor digesting non pretreated whole OFMSW had the best performance with the shortest HRT of 9 days. Conversely, for free liquid after pretreatment in two stage reactors at 20 day HRT methane production was tripled. In general, the performance of the dual stage digesters surpassed that of the single stage reactors. Cyclic BMP assays indicated that using an appropriate fraction of recycled effluent leachate can be implemented without negatively effecting methanogenic activity and biogas production. Based on the results obtained in this study, digestion of OFMSW by dual stage reactors without pretreatment appears to provide the best potential for waste stabilization in terms of biogas production and yield, process stability and volumetric loading rates.
Autoregression Models for Trust Management in Wireless Ad Hoc Networks

description: In this thesis, we propose a novel trust management scheme for improving routing reliability in wireless ad hoc networks. It is grounded on two classic autoregression models, namely Autoregressive (AR) model and Autoregressive with exogenous inputs (ARX) model. According to this scheme, a node periodically measures the packet forwarding ratio of its every neighbor as the trust observation about that neighbor. These measurements constitute a time series of data. The node has such a time series for each neighbor. By applying an autoregression model to these time series, it predicts the neighbors future packet forwarding ratios as their trust estimates, which in turn facilitate it to make intelligent routing decisions. With an AR model being applied, the node only uses its own observations for prediction; with an ARX model, it will also take into account recommendations from other neighbors. We evaluate the performance of the scheme when an AR, ARX or Bayesian model is used. Simulation results indicate that the ARX model is the best choice in terms of accuracy.

description: The ubiquity of Web 2.0 technologies has led to a seismic shift in the way educational services are delivered. It comes as no surprise then that e-tutoring—otherwise known as electronic or online tutoring—is quickly supplanting face-to-face tuition for reasons of both cost and convenience. While e-tutoring is an effective form of academic support for many students, its efficacy remains tenuous for those confronted with a digital divide that figures predominantly around geographic barriers, socio-economic status, and educational levels. Premised on diffusion research, this master's dissertation explores the implementation of an e-tutoring service known as Homework Help that has effected relatively low adoption rates. It uses a concurrent mixed-methods approach—including surveys, interviews, and focus groups—to examine the factors that have led to this low adoption rate. The results are presented via two journal articles situated within a larger meta-talk: The first article contrasts the adoption patterns apparent between rural and urban students, while the second article looks at the utility of diffusion research in examining educational technologies, as it explores the use of e-tutoring for applied stream students. The findings of this study suggest that rural and urban, as well as applied and academic student subgroups, differ in terms of their perception and adoption of e-tutoring. Implications for educational policy, especially in regards to rural education, are discussed.

description: Diurnal ﬂuctuations in volatility are a well-documented stylized fact of intraday price data. We investigate how this intraday periodicity (IP) aﬀects both ﬁnite sample as well as asymptotic properties of several popular realized estimators of daily integrated volatility which are based on functionals of M intraday returns. We demonstrate that most of the estimators considered in our study exhibit a ﬁnite-sample bias due to IP, which can however get negligible if the number of intraday returns diverges to inﬁnity. We suggest appropriate correction factors for this bias based on estimates of the IP. The adequacy of the new corrections is evaluated by means of a Monte Carlo simulation study and an empirical example.

description: Acrylamide, a substance potentially carcinogenic in humans, represents a very prevalent contaminant in food and is also contained in tobacco smoke. Occupational exposure to higher concentrations of acrylamide was shown to induce neurotoxicity in humans. To minimize related risks for public health, it is vital to obtain data on the actual level of exposure in differently affected segments of the population. To achieve this aim, acrylamide has been added to the list of substances of concern to be investigated in the HBM4EU project, a European initiative to obtain biomonitoring data for a number of pollutants highly relevant for public health. This report summarizes the results obtained for acrylamide, with a focus on time-trends and recent exposure levels, obtained by HBM4EU as well as by associated studies in a total of seven European countries. Mean biomarker levels were compared by sampling year and time-trends were analyzed using linear regression models and an adequate statistical test. An increasing trend of acrylamide biomarker concentrations was found in children for the years 2014-2017, while in adults an overall increase in exposure was found to be not significant for the time period of observation (2000-2021). For smokers, represented by two studies and sampling for, over a total three years, no clear tendency was observed. In conclusion, samples from European countries indicate that average acrylamide exposure still exceeds suggested benchmark levels and may be of specific concern in children. More research is required to confirm trends of declining values observed in most recent years. © 2022 by the authors

description: This paper presents results of an investigation into identifying reasons for students’ non-uniform assignment outcomes in a first year subject in the Civil Engineering discipline and proposees some effective measures to overcome this issue. The subject has been taught for three years since it was introduced in 2007. The assessment of the subject includes three assignments contributing 40% of the final result. In 2007 and 2008 the author observed that students performed well in the the first and third assignment, however student performance in Assignment 2 was poor. This observation was confirmed through statistical analysis of the students marks from these two years. In an attempt to rectify the less than satisfactory student results in assignment 2 a change was made to the amount of teaching and tutorial time allocated to preparing for this assignment in 2009. It was found that this increase in teaching time allocated to mathematical calculations produced significant positive outcomes. While student results in Assignment 2 improved to a satisfactory level, assignment 2’ remained the least performing assignment compared to other assignments in the subject. To gain a deeper understanding students were surveyed. The initial hypothesis of this study was that the mathematical calculation focus of Assignment 2 might be the reason for lower student performance, however results of the survey show that the majority of students did not agree with this hypothesis. Students reported that they found Assignment 2 interesting and they understood the concepts and theory that it was testing. It would appear that other factors, perhaps the timing of the assignment mid-semester competing with other subject assessment, may account for the dip in student results. The outcomes from this investigation inform a set of recommendations for future teaching of the subject.

description: Studies of recorded ground motions and simulations have shown that deep sedimentary basins can greatly increase the intensity of earthquake ground motions at medium and long periods, i.e. 1-4 s. While future earthquake design provisions are likely to account for basin amplification, the consequences of accounting for these effects are uncertain. By combining empirical and simulated seismic hazard characterizations that account for the effects of basins, this paper estimates key indicators of seismic performance, expressed in terms of earthquake-induced repair costs, for a series of 12-story reinforced concrete shear wall archetype buildings in Seattle, WA. The reference archetype is designed to comply with ASCE 7-16 minimum design requirements, which neglect basin effects. A series of code-prescriptive design enhancements, five in total, are also evaluated. The enhancements include: (a) increasing design forces, (b) decreasing in drift limits, and (c) a combination of these strategies. As an additional reference point, a performance-based design is also assessed. The performance of the archetype buildings is evaluated for the seismic hazard level in Seattle according to the 2018 National Seismic Hazard Model (2018 NSHM), which explicitly considers basin effects. Increasing design forces by 25% combined with a reduction in drift limits to 1.5% was found to be the most efficient of the seven design strategies considered, resulting in a 51% reduction in the average annual losses compared to the reference archetype. Incorporating physics-based ground motion simulations to represent the large-magnitude Cascadia subduction interface earthquake contribution to the hazard results in an average increase in annual losses of 28% compared to the 2018 NSHM.

The impact of networking on business performance: a case study of Malaysian SMEs

Year: 2024

description: Business networking, including the sharing of knowledge and exchange of information, and its impact on business performance has received significant recent attention in the literature, but there is scant literature analysing the relationship between business networking and business performance within the context of business constraints. In this paper the authors argue that the impact of business networking on business performance should, most appropriately, be examined within such a context. Numerous measures are developed in the paper aimed at capturing the extent and nature of business networking, business performance, and business constraints in the context, specifically, of small and medium enterprises. Then, using exploratory factor analysis and multiple regression techniques, data from 150 Malaysian SMEs reveal that networking has a positive and significant impact on business performance, while other perceived business constraints are found to be negatively and significantly linked to business performance. The results presented suggest that measures adopted by policy makers aimed at enhancing business networking and reducing perceived business constraints will have significantly beneficial effects upon the business performance of SMEs.
A Two-Year Longitudinal Study of Emotionally Focused Therapy for Couples: Maintenance and Predictors of Relationship Change
Creators: name: Wiebe, Stephanie

Year: 2014

description: Emotionally Focused Therapy for Couples (EFT) is an evidence-based couple therapy with excellent outcomes (Johnson, Hunsley, Greenberg & Schindler, 1999) and strong results in follow-up (Cloutier, Manion, Walker & Johnson, 2002). Although EFT strives to create lasting change for couples through the creation of secure attachment bonds, research has had yet to clarify how couples maintain changes across time. According to EFT, relationship satisfaction improvements are associated with and arise from the creation of secure attachment bonds that allow couples to turn to each other in times of stress, fostering resilience in the relationship across time (Johnson & Whiffen, 1999). One goal of this study was to test this assumption by modeling the trajectory of how relationship satisfaction and self-reported and behaviourally measured attachment security progress during the course of two years after finishing therapy. The trajectory of relationship satisfaction, and relationship specific self-reported and behaviourally measured attachment were modeled across pre-therapy, post-therapy and 6, 12, 18 and 24 months follow-up in a sample of 32 couples who received an average of 21 sessions of EFT. Results demonstrated a significant growth pattern using Hierarchical Linear Modeling (HLM: Raudenbush & Bryk, 2002) demonstrating increases in relationship satisfaction and secure base behaviour, and decreases in attachment anxiety from pre to post therapy that levelled off during the follow-up period. Although these results demonstrated strong EFT outcomes across follow-up, there was variability in outcomes. A second goal of this study was to investigate predictors of relationship satisfaction across follow-up. Results indicated that decreases in relationship specific attachment anxiety and avoidance, and increases in trust as well as depth of experiencing during therapy predicted higher relationship satisfaction across follow-up.

description: As the number of Indigenous people/s in Canadian cities is increasing, more research in the field of decolonization is needed to advance conceptual and empirical understanding of how to decolonize urban settler space. This thesis takes a critical qualitative and decolonization approach to investigate how Indigenous people/s experience urban settler space by using a case study of Indigenous students at the University of Ottawa. Through sharing circles, personal interviews, and reflexive journaling, I centre my participants’ experiences and perceptions of the University of Ottawa campus as space. In the first results chapter (Chapter 3), I present my participants’ perceptions of the built environment of the campus and in turn identify the contours of a settler space. In the next chapter (Chapter 4), I examine the participants’ experiences of the campus as a social space. Their responses reveal that settler spaces are imbued with settler norms – what I call settlernormativity – that often reproduce unequal settler-Indigenous relations in and through space. Drawing from my participants’ views on how to decolonize campus space, in Chapter 5, I propose acts of decolonization in space-time as a strategy to decolonize settler urban spaces.

description: Lingering in the topic of literary engagement, this article follows a reader enthralled by words and the significant non-space where fiction and reality intersect. Using Terry Fallis’ political satire “The Best Laid Plans,” a physical map of the reading is followed as I amble through the Ottawa sites depicted in the novel. In this literary pilgrimage, reading is considered as a corporeal (re)action with a series of educative affects. Contrasting this experience with common in-school reading practices, this narrative encourages the honouring of the individualized relationship between reader and text as well as highlighting the pedagogical value of dallying in a work of fiction. Drawing on concepts of spatiality, I contemplate the notion of the home city as a familiar and yet capricious place, made more significant by a fantastic connection. Reading in significant spaces has a lasting, sprawling outcome whereby text, place and reader are all affected.

description: Many-body quantum dynamics is a challenging problem that has induced the development of many different computational techniques. One powerful technique is the multiconfiguration time-dependent Hartree-Fock (MCTDHF) method. This method allows proper consideration of electronic correlation with much less computational overhead compared to other similar methods. In this work, we present our implementation of the MCTDHF method on a non-uniform cylindrical grid. With the one-body limit of our code, we studied the controversial topic of tunneling delay, and showed that our results agree with one recent experiment while disagreeing with another. Using the fully correlated version of the code, we demonstrated the ability of MCTDHF to address correlation by calculating the ground state ionization energies of a few strongly correlated systems.
Quantifying Basin Amplification in Southwest BC from Simulated M9 Cascadia Subduction Zone Earthquakes

description: Southwest British Columbia has the potential to experience large-magnitude earthquakes generated by the Cascadia Subduction Zone. Buildings in Metro Vancouver are particularly vulnerable to these earthquakes because the region lies above the Georgia sedimentary basin, which can amplify the intensity of earthquake ground motions. Studies of recorded ground motions and simulations have shown that deep sedimentary basins can greatly increase the intensity of earthquake ground motions at medium and long periods. Earthquake design provisions in Canada neglect basin amplification and the consequences of accounting for these effects are uncertain. By leveraging physics-based simulations of a suite of M9 Cascadia Subduction Zone earthquake scenarios, this paper develops site-specific and period-dependent basin amplification factors throughout Metro Vancouver. The M9 simulations, which explicitly account for basin amplification, are benchmarked against ground motion models (GMMs), i.e. BC Hydro, which neglect such effects. The results indicate that for sites outside the basin, the empirical and simulated seismic hazard estimates are consistent. However, for sites within the basin and periods in the range of 1 to 4 s, GMMs significantly underestimate the hazard. The simulated M9 ground motions are also benchmarked against probabilistic estimates of the hazard from the 2015 National Building Code of Canada. Four different hazard levels are considered: 2%, 5%, 10% and 40% probability of exceedance in 50 years. At sites within the Georgia basin, the M9 simulations, which have a return period of approximately 500 years, far exceed the 10% in 50-year probabilistic estimates of the hazard. The proposed basin amplification factors vary across the region as a function of basin depth, reaching values as high as 9.2 at a 2 s period. The proposed factors are intended for use in design until basin amplification is explicitly considered within Canada’s national seismic hazard model.

description: In this paper, the conjugate gradient (CG) algorithm is modified using the RLS normal equation and new data windowing scheme. It is known that CG algorithm has fast convergence rate and numerical stability. However, the existing CG algorithms still suffer from either slow convergence or high misadjustment compared with the RLS algorithm. In this paper, the parameter beta for CG algorithm is redesigned from the RLS normal equation and a general data windowing scheme reusing the data inputs is presented to solve these problems. The optimal property of parameter alpha is also analyzed using the control Lyapunov function (CLF) of the square deviation of weight error vector. The superior performance of the proposed algorithms over the RLS algorithm and the other existing CG algorithms is demonstrated by computer simulations.

description: The antibacterial behavior of HA-Ag (silver-doped hydroxyapatite) nanopowder and their composite coatings were investigated against Escherichia coli (DH5α). HA-Ag nanopowder and PEEK (poly-ether-ether-ketone)-based HA-Ag composite powders were synthesized using in-house powder processing techniques. Bacteria culture assay of HA-Ag nanopowder and their composite powders displayed excellent bacteriostatic activity against E. coli. The antibacterial activity increased with increasing concentration of HA-Ag nanoparticle in these composite powders. These nanocomposite powders were subsequently used as feedstock to generate antibacterial coatings via cold spray technology. The ratios of HA-Ag to PEEK in their composite powders were 80:20, 60:40, 40:60, and 20:80 (wt.%). Microstructural characterization and phase analysis of feedstock powders and as-deposited coatings were carried out using FESEM/EDX and XRD. Antibacterial nanocomposite HA-Ag/ PEEK coatings were successfully deposited using cold spraying parameters of 11-12 bars at preheated air temperature between 150 and 160 °C. These as-sprayed coatings of HA-Ag/PEEK composite powders comprising varying HA-Ag and PEEK ratios retained their inherent antibacterial property as verified from bacterial assay. The results indicated that the antibacterial activity increased with increasing HA-Ag nanopowder concentration in the composite powder feedstock and cold-sprayed coating.

description: This thesis examines the corporate appropriation of human right to water and sanitation discourse. David Harvey’s concept of accumulation by dispossession provides the political- economic basis for this analysis while enabling a discussion of water conflicts that looks at neoliberalization strategies beyond the privatization of services. Inspired by Gramsci’s notion of a “war of position”, this thesis investigates the role of corporate appropriation of human right to water and sanitation discourse in legitimating strategies of accumulation by dispossession. Through content and critical discourse analysis of publications of a corporate policy consortium called the 2030 Water Resources Group the investigation concludes that this lobby group simultaneously undermines human rights while actively using key elements of rights discourse to advance its neoliberal water policy objectives.

description: The UV filters octocrylene (OC) and 2-ethylhexyl salicylate (EHS) are commonly used in sunscreens and frequently detected in environmental media. However, knowledge on human exposures is scarce. In this human biomonitoring (HBM) study, we analyzed concentrations of exposure biomarkers specific to OC (CPAA, DOCCA, 5OH-OC) and EHS (5OH-EHS, 5oxo-EHS, 5cx-EPS) in 24-h urine samples (n=420) from the German Environmental Specimen Bank (ESB). These samples were collected from German students (20-29 years; 30 males/30 females per year) between 1996 and 2020 (4-year intervals; collection in winter). We found continuously increasing OC and EHS exposures (Jonckheere-Terpstra; p < 0.001) documented by very few to no samples with concentrations of the most sensitive biomarkers CPAA and 5cx-EPS above the limit of quantification (LOQ) in 1996 (5 % and 0 %, respectively) and reaching 100 % and 93 % above the LOQ in 2016, with median concentrations of 4.79 and 0.071 (micro)g/L, respectively. In 2020, biomarker concentrations slightly decreased to 3.12 (micro)g/L CPAA (97 %>LOQ) and 0.060 (micro)g/L 5cx-EPS (88 %>LOQ). This general trend was confirmed by the other biomarkers, however at lower detection rates. Based on metabolite excretion in the 24-h urine samples and human toxicokinetic data, we calculated maximum daily intakes (DI) of 17 (micro)g/(kg bw * d) OC and 59 (micro)g/(kg bw * d) EHS. Based on a derived no-effect level (DNEL) of 0.8 mg/(kg bw * d), the OC exposures of individuals in our study did not indicate any health risk. Similarly, for EHS all biomarker concentrations were well below the HBM-I values of 12 (micro)g/L 5OH-EHS and 11 (micro)g/L 5cx-EPS. Our data proves the general applicability of specific OC and EHS metabolites for HBM in the general population and shows clearly increasing exposures. Higher (co-)exposures must be expected in populations with increased sunscreen use such as (summer) vacationers, children and outdoor workers. © 2023 The Author(s).
A systematic approach for designing a HBM Pilot Study for Europe

description: The objective of COPHES (Consortium to Perform Human biomonitoring on a European Scale) was to develop a harmonised approach to conduct human biomonitoring on a European scale. COPHES developed a systematic approach for designing and conducting a pilot study for an EU-wide cross-sectional human biomonitoring (HBM) study and for the implementation of the fieldwork procedures. The approach gave the basis for discussion of the main aspects of study design and conduct, and provided a decision making tool which can be applied to many other studies. Each decision that had to be taken was listed in a table of options with their advantages and disadvantages. Based on this the rationale of the decisions could be explained and be transparent. This was important because an EU-wide HBM study demands openness of all decisions taken to encourage as many countries as possible to participate and accept the initiative undertaken.Based on this approach the following study design was suggested: a cross-sectional study including 120 children aged 6-11 years and their mothers aged up to 45 years from each participating country. For the pilot study the children should be sampled in equal shares in an urban and a rural location. Only healthy children and mothers (no metabolic disturbances) should be included, who have a sufficient knowledge of the local language and have been living at least for 5 years at the sampling location. Occupational exposure should not be an exclusion criterion. Recruitment should be performed via inhabitant registries or schools as an alternative option. Measures suitable to increase the response rate should be applied. Preferably, the families should be visited at home and interviewed face-to-face. Various quality control measures to guarantee a good fieldwork performance were recommended.This comprehensive overview aims to provide scientists, EU officials, partners and stakeholders involved in the EU implementation process full transparency of the work carried out in COPHES. Thus this report presents the discussion and consensus in COPHES on the main aspects of designing and conducting fieldwork of a human biomonitoring study. Furthermore, it provides an example for a systematic approach that may be useful to other researchgroups or pan-European research initiatives. In the study protocol that will be published elsewhere these aspects are elaborated and additional aspects are covered (Casteleyn et al., 2012). Meanwhile the respective pilot study DEMOCOPHES had been conducted and assessed. The results and lessons learned will be published elsewhere.
