description: There is an increased prevalence of disordered eating in individuals with type 1 diabetes (T1DE). This includes behaviours such as binging, over-exercise and laxative use, as well as intentional misuse of insulin (“Diabulimia”), a behaviour unique to those with type 1 diabetes (T1D). T1DE carries risk of long-term complications such as blindness and nerve damage, and mortality rates are significantly increased.           Due to the dangers associated with T1DE, early identification and intervention are important. However, clinicians lack confidence and training in relation to the identification and management of T1DE. Furthermore, there is a lack of specialist services available. Part One of this portfolio presents a unique review of freely available webpages providing information and support for those with T1DE. The findings of the review suggest the webpages predominantly focus on information about Diabulimia and offer advice to individuals around speaking to those around them, including healthcare professionals, if they are experiencing difficulties. However, the webpages do not provide detailed information on other disordered eating behaviours and may be inaccessible due to their high reading levels and unclear action points.            Part Two presents an empirical study exploring healthcare professionals’ attitudes to screening for disordered eating in individuals with T1D. The findings suggest healthcare professionals find these conversations difficult due to fears such as triggering behaviours by asking questions and concerns about how those with T1D may react. Furthermore, the lack of specialist services and clinicians’ perceptions of a lack of knowledge contributed to a reluctance to ask questions and to use screening measures with this population.

The use of automatic speech recognition in cloud-based remote simultaneous interpreting

Subjects: Remote Simultaneous Interpreting (RSI)
Computer-assisted interpreting
Automatic speech recognition

description: The growing practice of remote simultaneous interpreting (RSI) via cloud-based digital platforms, which has gained momentum during the COVID-19 pandemic, has opened up new opportunities for interpreters to provide simultaneous interpreting (SI) services. While under-researched, cloud-based RSI may have similar implications to the ones associated with booth-based RSI. Research has shown that booth-based RSI can be more tiring and stressful than conventional simultaneous interpreting and that it is more demanding in terms of information processing and mental modelling (Moser-Mercer, 2003/2005), with perceived negative implications for interpreting quality (Roziner and Shlesinger, 2010). Bringing together research on RSI and on the use of automatic speech recognition (ASR) as a computer-assisted interpreting (CAI) tool, which has been advocated as a means to support interpreters in different SI configurations (e.g., Defrancq and Fantinuoli, 2020), this study investigates the application of full ASR-generated transcripts in cloud-based RSI settings, examining their effect on interpreters’ output quality and overall user experience. As part of the experimental design, 16 professional conference interpreters performed a controlled interpreting test consisting of a warmup speech (not included in the analysis), and four speeches, i.e., two lexically dense speeches (LD) and two fast speeches (F), presented with and without ASR support. With regards to interpreting quality, which was measured by the NTR Model (Romero-Fresco and Pöchhacker, 2017), a system originally devised for assessing the accuracy of interlingual respeaking performance, results show higher average NTR scores across both speech types when ASR support is available. However, while LD speeches benefit statistically from ASR, F speeches show less improvement. Besides, the application of ASR-generated live transcripts seems to entail a loss in stylistic quality. Interpreters’ experiences vary, with most participants using ASR transcripts randomly or when facing difficulties and having different opinions regarding their experiences and the integration of ASR in cloud-based RSI. The study recommends exploring the use of ASR as a CAI tool with different speech types and ASR displays, its cognitive implications, and the role of CAI training, in order to inform best practices for effective ASR integration in cloud-based RSI.

description: Wurtzite based materials have the advantages of being cheap, no-toxic and offering excellent opto-electrical, piezoelectric and pyroelectric properties. The nanocrystalline wurtzite ZnS, being a room temperature stable material unlike its bulk counterpart, is interesting because of its potential in piezoelectric and pyroelectric energy harvesting. In this work we aimed to tailor a simple synthesis method for nanocrystalline wurtzite production, which would be easy to scale up.
 We used the well-known reaction of zinc chloride with thiourea or sodium sulfide dissolved in ethyl glycol at a carefully controlled molar ratio in medium temperature conditions (140-150°C) to produce pure, nanocrystalline ZnS in the hexagonal (wurtzite) phase, via a series of consecutive experiments. The amount of solvent was kept the same (60 ml of ethyl glycol) by re-using what remained of the solvent from the previous reaction and topping up the quantity lost. The productivity yield increased over 6 successive reactions from 156 mg to 446 mg per batch at a constant mMZn/mMS = 1 ratio. The obtained nanopowder has been characterized using TG, BET, FTIR, TEM and SEM techniques. Our plan is to build an in-house pilot plant that should produce substantial amounts of wurtzite ZnS nano-powder in an environmentally friendly and cost effective way.

description: The current rate of unemployment for individuals with enduring mental health difficulties has been a cause for debate in the current political world. Accessing psychological therapy and support is often vital to help individuals with overall quality of life. The complexity of accessing mental health support whilst in employment is not yet fully understood. This thesis aimed to determine the impact and experience of being in employment and having a mental health diagnosis or illness. Part one of this portfolio presents a reflexive thematic analysis of factors associated with accessing NHS mental health support whilst in employment. The findings suggested that perceived and experienced stigma, unpredictability and NHS structures often mean individuals face a choice of either accessing psychological help or going to work. Part two presents a policy review that investigated the current UK based policies aimed at employers and support for mental health in the workplace. The findings of the review suggested that policies are available with key recommendations for increased mental health awareness, embedded wellbeing practices and awareness of legislation. However, there is limited accountability to ensure these recommendations are followed.

Aspects of the manufacture and performance of a compression moulded carbon fibre composite for automotive applications.
Creators: name: Kite, Samuel F.
Publisher: name: University of Surrey
Year: 2020

description: A need for light-weighting in the automotive industry is leading to more widespread adoption of composite materials. The high cost of these materials, however, is leading to a search for lower cost solutions. Carbon fibre-reinforced sheet moulding compound (C-SMC) is proposed as a possible cost-effective solution but has several barriers to use; namely warpage of components, and high variability of mechanical properties. This thesis investigated possible factors affecting the distortion of components and found that the distortion, measured by a laser scanner on a ROMER arm, was related to the orientation distribution of the reinforcement affected by the flow, characterised by X-ray computed tomography. It was found that use of cooling jigs could control this warpage to produce in-tolerance components. These findings have already been implemented by the sponsor company to enable use of this material in multiple products. The effects of coupon width, thickness, and mould coverage on apparent tensile strength and Young’s modulus were investigated. This found that strength increases when the coupon width reaches twice the length of the reinforcement. The strength was found to increase with thickness according to a logarithmic relationship, with non-significant differences occurring after the thickness had reached 4 mm thickness. The strength was found to decrease with increasing mould coverage for the mould coverages tested. The modulus was found to not correlate to coupon width, although there was a decrease in variation at 50 mm width. Similarly, the Young’s modulus was not found to change with increasing thickness, but the variance did decrease. The Young’s modulus increased with decreasing mould coverage. This allowed definition of the geometry of a tensile test coupon to increase the confidence in the determined mechanical properties for future test programmes.

description: We consider the problem of extracting a specific feature from a noisy signal generated by a multi-channels Remote Field Eddy Current Sensor. The sensor is installed on a mobile robot whose mission is the detection of anomalous regions in metal pipelines. Given the presence of noise that characterizes the data series, anomaly signals could be masked by noise and therefore difficult to identify in some instances. In order to enhance signal peaks that potentially identify anomalies we consider an entropy filter built on a-posteriori probability density functions associated with data series. Thresholds based on the Neyman-Pearson criterion for hypothesis testing are derived. The algorithmic tool is applied to the analysis of data from a portion of pipeline with a set of anomalies introduced at predetermined locations. Critical areas identifying anomalies capture the set of damaged locations, demonstrating the effectiveness of the filter in detection with Remote Field Eddy Current Sensor.
How to Create and Maintain a Social Problem: Critically Deconstructing the Canadian National Drug Strategies 1987-2014

description: This thesis explores the evolution of the discourses that constitute the social problem of drug use in Canada as described throughout the three Canadian drug strategies: the National Drug Strategy 1987-1992, the Canadian Drug Strategy 1992-2007 and the National Anti-Drug Strategy 2007-2014. In order to do so the author engages with Foucaudian concepts of discourse, power and knowledge to conduct an archaeological analysis of government texts produced during each time period. In particular, the author places a focus on how drug use, drug users, the impact of drug use on Canadian society and the perceived necessary responses to the drug problem are constructed through various discourses. The findings help the author propose a framework to examine how social problems may be politicized in general. The framework highlights the tendency for social problems to emphasize appropriate social norms, be selective in their incorporation of evidence, marginalize those who are considered problematic and politicize objects in a vague manner.

description: A 30.5 cm diameter, detonation driven shock tube facility has been designed, constructed and tested. The design goals of the shock tube were to reproduce free field blast wave profiles on a laboratory scale using atmospheric gaseous detonation as the energy source. Numerical simulations were utilized to explore the gas dynamic evolution inside detonation driven shock tubes and to select the optimal design parameters for the shock tube.The Friedlander profile was used to evaluate the generated pressure profiles as an approximation of free field blast waves. It has been found that the detonation driver length should be kept below 20% of the total length of the tube in order to produce Friedlander waves. Additionally, it has been found that an annular vent can be added to the shock tube to enhance the negative phase of the blast profile, more accurately reproducing real free field blast waves. The shock tube has been constructed in a modular fashion from 2.54 cm thick steel tubing. An adjustable bag type diaphragm has been employed to allow for a variable driver size and a high voltage ignition system is used to initiate detonation in the driver section. Due to the available location for the shock tube, tests using the vented configuration could not be accomplished for safety reasons. Conducted experiments produced results that agree well with corresponding numerical simulations. Overall, the shock tube design was successful in creating Friedlander blast waves. At the time of writing, a manufacturer error in correctly reporting the specifications of the clamps used on the shock tube resulted in a lower maximum pressure of operation.
Death, the doctor, and motor neurone disease : the lived experience of doctors working with people dying from MND.
Creators: name: Dilley, Sophie
Publisher: name: University of Surrey
Year: 2020

description: Working with patients who are dying has been perceived as emotionally challenging (Meier, Back & Sean Morrison, 2001), with increased awareness of concepts such as burnout and compassion fatigue pervading the media and general public. The ambiguity into the conceptualisation of these terms as well as their increasing embeddedness in the medical model risks pathologising existential responses to the givens shared by all of humanity; mortality, temporality, and making meaning. Research in the field of death and dying continues to focus on areas such as oncology despite increasing prevalence of neurodegenerative diseases among the population (Talbot & Marsden, 2008). This research seeks to contribute to the field of MND by exploring the lived experience of doctors working with patients with MND. Semi-structured interviews were conducted with six participants, and subsequently analysed using interpretative phenomenological analysis (IPA). This research found that doctors were engaged in various meaning-making processes regarding their relationship to self and the other as patient. The super-ordinate themes identified focused on the way in which tensions were borne out of a dynamic movement of the inter-subjective relational encounter between self and other. These yielded three super-ordinate themes consisting of ‘It’s enjoyable, it’s depressing, it’s important’, ‘The boundaries between self and other’, and ‘People die’. The findings highlighted that though participants were engaged in practices of experiential avoidance to possibly distance themselves from the impact of their work, the relationality of the doctor-patient encounter had the potential to transcend the boundaries created. Furthermore, the impact of working with patients dying from MND appeared to be mitigated by the meaning doctors attributed to their work and its existential context. The implications for Counselling Psychology and allied fields are discussed, as well as limitations and suggestions for future research.

description: Health professionals who engage in healthy lifestyle behaviors are more likely to promote their patients’ health. We evaluated health status, behaviors, and beliefs of students (future health professionals) and staff in four health sciences faculties, Kuwait University. In total, 600 students and 231 staff participated in this descriptive cross-sectional study. Questionnaire surveys were used to evaluate lifestyle-related practices and participants’ beliefs about these practices, in addition to health-related objective measures, e.g., heart rate, blood pressure, and body mass index. Overweight/obesity was prevalent among the participants (staff, 68.7%, students, 48.1%; p < 0.001); 57% of staff had suboptimal resting blood pressures. About half of the participants reported being moderately physically active (staff, 44.8%, students, 52.6%; p < 0.05), and most reported moderate/high stress (staff, 88.8%, students, 90.9%; p > 0.05). Only 25.1% of staff and 27.9% of students reported at least 8 h sleep nightly (p > 0.05). Staff reported healthier dietary practices than students (p-value range < 0.001–0.02). Overall, the participants had sub-optimal health indices. A marked gap existed between participants’ beliefs about healthy lifestyle practices and their actual health status. Healthy lifestyle programs are needed on campus with respect to diet, exercise, and stress management. As emerging health professionals, students in health sciences faculties, Kuwait University, need exposure to a health-promoting environment including healthy staff as role models.

description: Methylation is a post-translational modification which occurs on lysine and arginine residues. Methylation is difficult to detect due to its low abundance and lack of charge. Our laboratory previously developed a novel enrichment approach, ProMENADe, for lysine and arginine methylation in the human embryonic kidney (HEK) 293T cell line which is coupled with mass spectrometry. Simplifying a lysate with subcellular fractionation prior to enrichment increased the identification of methylation sites by 39.5% while using multiple proteases for digestion increased identification by 27%. Combining these methods yielded a 47.2% increase. Analysis at the 1% methylation level FDR filtered for C-terminal methylation identified 169 sites and further analysis revealed 74 of these sites overlap with the PhosphoSite database. This ProMENADe enrichment strategy yielded 95 novel methylation sites to the field and can be a key tool in the field of methylation allowing for the enrichment and identification of methylated proteins.

description: Due to its rising prevalence and associations with physical and mental health problems, loneliness is a public health concern (Office of National Statistics, 2021). This thesis aimed to explore factors involved in the aetiology of loneliness. Part one of this portfolio presents a systematic review examining how attachment styles relate to loneliness in adults. Findings suggest that individuals with insecure attachment styles, both anxious and avoidant types, are more likely to report loneliness. Part two of this portfolio presents an empirical paper that investigates whether adverse childhood experiences (ACEs) predict trajectories of loneliness over time, distinguishing between transient loneliness (episodic loneliness that comes and goes) and chronic loneliness (loneliness that is pervasive and enduring). Findings demonstrate that experiencing childhood adversity increases the likelihood of following a chronic loneliness trajectory but does not impact the likelihood of experiencing transient loneliness. This paper therefore sheds light on our understanding of chronic loneliness, which is important as chronic loneliness is associated with poorer health and wellbeing outcomes relative to transient loneliness. Together, both papers highlight that the way in which people appraise social relationships, and their past experiences with social relationships, are important predictors of loneliness which persists into adulthood. Clinically, this suggests that simply increasing the quantity of social contact will not be sufficient in tackling loneliness as this does not alter the way in which social relationships are appraised. This has important implications when we consider that social prescribing has been utilised as a primary means to tackle loneliness.

description: The dichotomy of contrastive and allophonic phonological relationships has a long-standing tradition in phonology, but there is a growing body of research (see Hall, 2013, for a review) that points to phonological relationships that fall between contrastive and allophonic. The criteria most commonly used to define phonological relationships or resolve cases of ambiguous phonological relationships – namely (a) predictability of distribution, and (b) lexical distinction – are not always able to account for observed sound patterns. The main goal of this dissertation is to identify and apply quantitative measures (relative frequency and minimal pair counts) to the traditional criteria in order to better account for cases of intermediate phonological relationships or, in other words, to account for different strengths and degrees of contrast. Twenty native speakers of Laurentian French (LF) participated in Experiment 1, an AX discrimination task, and Experiment 2, a four-interval AX (4IAX) task, which tested the broader relationships of allophony and contrast. It was hypothesized, based on previous experiments (Boomershine et al., 2008; Dupoux et al., 1997; Ettlinger & Johnson, 2009; Johnson & Babel, 2010; Kazanina et al., 2006; Peperkamp et al., 2003; Pruitt et al., 2006), that phones in an allophonic relationship would be more difficult to perceive than phones in a contrastive relationship. Results confirmed previous findings, with longer reaction times for allophonic pairs as compared to contrastive pairs in the AX task (p

description: A business process is a defined collection of linked structured tasks, activities, and decisions performed together to produce a desired set of results in order to achieve business goals on behalf of the organization. Companies are increasingly moving their business processes online using Business Process Management (BPM) tools and technologies. With BPM, online business processes are defined by an explicit business process model that flexibly combines and orchestrates forms delivered through a web browser to integrate tasks performed by people, and web services accessible through Internet protocols to integrate tasks performed by software. Often the approach to quality assurance for online business processes is similar to what would be done with any other web application. This is insufficient since it only provides rudimentary verification of single user behavior whereas the orchestration of tasks across many users and software systems can be quite complex. As well, a simple web application testing approach does not leverage the defined model for a business process to ensure consistency, completeness and enable automation. Nor will such an approach validate that a business process is contributing towards the achievement of business goals. A more systematic approach is required. This thesis proposes a quality assurance framework to provide a repeatable, systematic, cost-efficient approach to quality assurance for BPM. A prototype framework was implemented and evaluated using two case studies, including one case study that was developed in collaboration with a local hospital to support a business process for cancer care assessment.
Voice-hearers’ understanding and experience of help: an interpretative phenomenological analysis.
Creators: name: McFie, Clare L.
Publisher: name: University of Surrey
Year: 2020

description: Objectives: The literature on voice-hearers’ experience of help is relatively scant and the forms of help studied tend to be defined by researchers. The present study aims to contribute to the extant literature by exploring what help means to voice-hearers and how they experience it in the context of their lives. Method: Six participants who identified as voice-hearers and who had experiences of help took part in semi-structured interviews. The interviews were transcribed verbatim and analysed using Interpretative Phenomenological Analysis (IPA). Results: The analysis produced four superordinate themes representing different facets of voice-hearers’ lived experience of help. These were: 1. Treat me like a human being; 2. The darker side of help; 3. Like moving to a new country; and 4. Becoming agents of change. Conclusions: Voice-hearers are very aware of and sensitive to the interpersonal nature of help and this can have a profound influence on whether their experiences of help are positive or negative. Importantly, voice-hearers’ relationship with their voices can be a source of help as well as distress. It is possible that voice-hearers do not need help for voices but rather for the underlying trauma of which voices may be a manifestation. Finally, help can be experienced as a journey and this conceptualisation may usefully inform clinical practice.

description: Commercial ebullated bed hydroprocessors, such as the LC-Finer, are used for the production of synthetic crude oil by upgrading bitumen extracted from the Canadian oil sands. The objectives of this thesis were to experimentally determine bubble characteristics at industrially relevant operating conditions for the design and optimization of the reactor’s recycle pan, as well as to investigate the impact of a catalyst density distribution on the reactor’s fluidization behaviour. High gas holdups have been reported for this type of industrial unit. As a result, high gas holdup conditions were required to assess the commercial unit fluid dynamics. Industrial conditions for the bubble characteristics in the reactor freeboard were simulated in a high pressure gas-liquid bubble column operating at 6.5 MPa using nitrogen and a 0.5 wt.% aqueous ethanol solution. Local bubble characteristics, including gas holdups, bubble rise velocities, and chord lengths, were investigated under various operating conditions using a novel monofibre optical probe designed for high gas holdup and elevated pressure. High gas holdups were achieved (up to 60%) and relatively narrow chord length distributions were observed, where 90% of the bubbles diameters were 1.0 mm or less. The energy dissipated through the distributor plate was shown to have a significant impact on the initial bubble size generated and high gas holdups were also achieved at atmospheric pressure by varying the open-surface area of the distributor. As a result, the impact of catalyst density distribution on local fluidization behaviour was investigated at atmospheric pressure using the previously designed high energy dissipation gas-liquid distributor plate and a 0.5 wt.% aqueous ethanol solution. Fresh and spent hydroprocessing catalysts having relatively narrow and wide density distributions were compared. The introduction of gas greatly impacted the fluidized bed dynamic by rendering the bed-freeboard interface diffuse at low superficial liquid velocity. Bed interface fluctuations were significantly reduced at elevated liquid flow rate due to average bubble size reduction caused by high shearing through the gas-liquid distributor plate. Solid holdup was most affected by the density distribution where bed expansion/contraction was dependent of the liquid flow rate due to varying particle-bubble dynamics.

description: The objective of this study is to investigate the feasibility of depositing 1.5 mm thick titanium coatings, as a repair method for aerospace Ti-6Al-4V substrates, using two new commercially available processes: Low Pressure Cold Spray (LPCS) and Pulsed Gas Dynamic Spray (PGDS). The coatings produced were examined and characterized by their porosity level, microhardness, adhesion strength, particle flattening ratio, wipe tests, fracture surface type and wear tests. Phases and chemical composition were determined using X-Ray diffraction analysis and energy dispersive spectroscopy, respectively. It was found that both spraying processes are capable of producing dense, hard and oxide-free coatings using specific parameters. Finally, as a first step towards repair implementation of these processes, damages were simulated on Ti-6Al-4V samples, which were successfully repaired with low porosity and high hardness levels. The feasibility of repairs was confirmed, the next step will consist in qualification testing to assess coating performances under real life application.
Mobile phones and sustainable agriculture based livelihoods: a case study of smallholder farmers in the Ashanti and Brong-Ahafo regions, Ghana

description: This study investigates the role of mobile phones in the livelihood development of farmers in the Ashanti and Brong-Ahafo Regions, Ghana. It seeks to uncover how farmers use their mobile phones and the outcomes associated with that use, as well as the factors that make mobile phones more or less useful. In order to answer these questions, a grounded theory approach was carried out using both qualitative interviews (n=48) followed by a manual content analysis, and a quantitative questionnaire (n=160) that provided for a statistical analysis of 4 communities in the Ashanti region and 4 communities in the Brong-Ahafo Region, Ghana. In doing so it was possible to identify critical challenges within important aspects of the production process and evaluate the use and usefulness of mobile phones in addressing these challenges. Findings show that mobile phones were generally useful for sending and receiving financial capital, seeking information on pesticides and fertilizers, organising farm labour, and searching for yam sale pricing information when carrying out temporal sales arbitrage. Mobile phones were seen as somewhat useful for liaising with extension officers and less useful for the critical processes of obtaining subsidized fertilizer. It was also found that individuals carry out the processes of transferring money, organising labour, and obtaining yam sale pricing information using combinations strategies defined as: (1) heavily focused on the use of the phone, (2) selective use of the phone, and (3) not making use of the phone. Individuals implementing strategies heavily focused on mobile phone use tended to have smaller farms and lower monthly incomes when compared to individuals employing alternative combinations of strategies. According to these results and subsequent theory building, this research presents a framework for the ICT related capital required for ICT related strategies to be carried out, as well as the external structural barriers occurring in the study area, and resulting in a failure to translate the use of mobile phone within strategies and processes into larger outcomes. While the study group as a whole is experiencing a progressive trend of decreased vulnerability and positive livelihood development, the widespread and complex use of the mobile phone has not resulted in a transformation of livelihood outcomes.

description: The Baltic Sea is under considerable ecological pressure from nutrient input originating from land-based diffuse sources and nutrient losses caused by agricultural land use. Significance of the latter source is increasing especially as within the framework of HELCOM, all Contracting Parties have made considerable efforts to build and extend municipal wastewater treatment plants and have declared in a binding manner to introduce phosphate free laundry detergents during upcoming years. Nutrient inputs are responsible for causing eutrophication, toxic algae blooms, hypoxic and anoxic zones at the sea bottom and thus jeopardize the economic basis of both fishery and tourism. The environmental burden from nutrient loads is reduced if nutrients in agriculture are applied in a more efficient manner. Fertilizers are meant to optimize crop yields and not to end up in ground and surface waters. Comprehensive nutrient bookkeeping provides a basic prerequisite (tool) for efficient nutrient use in agricultural holdings; this applies as well for fertilizer planning ex ante as for nutrient balancing ex post. Therefore in October 2013 the environment ministers of the HELCOM countries decided during their conference in Copenhagen to introduce nutrient bookkeeping on farm level in all Contracting Parties by the end of 2018. A platform for these activities should be provided by the HELCOM Group on Sustainable Agricultural Practices, a subsidiary body of HELCOM. Germany is currently holding the chairmanship of this group. This report is a record of the event, produced by the Chamber. It contains all presentations and identifies relevant steps for upcoming years to be taken by and in the HELCOM countries.

adult skeletal myogenesis

description: Adult skeletal muscles can regenerate after injury due to the presence of satellite cells, a quiescent population of myogenic progenitor cells characterized by expressing the transcription factor Pax7. Once activated, satellite cells repair the muscle damage and replenish the stem cell niche due to the coordinated function of several transcription factors including Pax7 and the myogenic regulatory factors (MRFs). MRFs are skeletal muscle-specific transcription factors that can convert non-muscle cells into the myogenic lineage. MRFs are known to cooperate with other transcription factors in regulating the complex transcriptional network driving myogenic differentiation of muscle progenitors. The Six4 transcription factor emerges as a strong candidate for cooperating with MRFs. Six4 is expressed in skeletal muscles; the lack of a muscle development phenotype in Six4-null mice has been attributed to compensation by other Six family members. However, this did not exclude a critical role for Six4 during muscle development as Six1;Six4 double mutant mice show a more severe muscle phenotype than Six1 mutant mice. Nevertheless, the role of Six4 during adult muscle regeneration has never been addressed. I combined a partial loss-of-function of Six4 with high-throughput approaches to address the role of Six4 during adult skeletal muscle regeneration. I observed an important function of Six4 during muscle regeneration in vivo and in in vitro cell models. Using RNA interference assays against Six4 in tibialis anterior muscle regeneration after cardiotoxin-induced muscle damage, I observed for the first time that Six4 plays a role in proper muscle regeneration. The ability of the MRF MyoD, a central regulator of skeletal myogenesis, to convert a non-muscle cell model into the myogenic lineage was impaired with attenuated Six4 expression. I employed genome-wide approaches by combining ChIP-sequencing with gene expression profiling and identified a set of muscle genes coordinately regulated by both Six4 and MyoD. Throughout the genome, the cooperation between Six4 and MyoD was associated with binding of the H3K27me3 demethylase Utx and depletion of the H3K27me3 repressive chromatin mark. Together, these results reveal an important role for Six4 during adult muscle regeneration, and suggest a widespread mechanism of cooperation between Six4 and MyoD that correlates with modifying the epigenetic landscape of the regulatory regions of a large set of genes needed for efficient myogenesis.

Agents in a multi-cultural world: towards ontological reconciliation
Creators: name: Lister, Kendall

Publisher: name: Swinburne
Year: 2024

description: In order to function effectively, agents, whether human or software, must be able to communicate and interact through common understandings and compatible conceptualisations. In a multi-cultural world, ontological differences are a fundamental obstacle that must be overcome before inter-cultural communication can occur. The purpose of this paper is to discuss the issues faced by agents operating in large-scale multi-cultural environments and to argue for systems that are tolerant of heterogeneity, illustrating the discussion with a running example of researching and comparing university web sites as a realistic scenario representative of many current knowledge management tasks that would benefit from agent assistance. We then discuss the efforts of the Intelligent Agent Laboratory toward designing such tolerant systems, giving a detailed presentation of the results of several implementations.

description: The mental health of children and young people has garnered increasing attention within public health initiatives, psychological research, and clinical practice. Young people with more complex presentations are suggested to have significantly worse health and social outcomes than their mainstream counterparts, which are reported to persist and increase in severity across the lifespan. There exists a dearth of attention afforded to some heterogeneous groups, including young people who present with harmful sexual behaviours (HSB). This portfolio contains two papers exploring this group.                        
Part A presents a conceptual review and narrative synthesis of research exploring the conceptualisation of ‘problematic sexual behaviours’ (PSB) of typically developing children and young people within the literature, to assess definitional clarity and consistency. The papers were considered through the lens of Hackett’s (2010) prominent model and continuum of sexual behaviours and this review tells the story of the extent to which current literature aligns with Hackett’s conceptualisation of PSB. The findings raised an important question regarding the sufficiency and utility of a single model, the necessity of a model that is workable and practical and identified implications for researchers, policymakers, legislators, services, and communities.
Part B presents a qualitative paper, exploring how community-based multi-agency and multi-disciplinary professionals make sense of girls (under 18 years) with HSB. The final themes elucidated pertinent individual and societal attitudes and assumptions that may influence professional approaches and responses to this population. Likewise, findings identified theoretical and clinically relevant implications, including for children and young people and their communities, service delivery and professional practice.
