description: The generation of microwaves from optical signals suffers from thermal and shot noise inherent in the photodetection process. This problem is more acute at lower pulse repetition rates where photodiode saturation limits the achievable signal-to-noise ratio. In this paper, we demonstrate a 10-15 dB reduction in the 10 GHz phase noise floor by multiplication of the pulse repetition rate. Starting with a 250 MHz fundamentally mode-locked erbium(Er):fiber laser, we compare two different approaches to repetition rate multiplication: Fabry-Perot cavity filtering and a cascaded, unbalanced Mach-Zehnder fiber-based interferometer. These techniques reduce the phase noise floor on the 10 GHz photodetected harmonic to -158 dBc/Hz and -162 dBc/Hz, respectively, for Fourier frequencies higher than 100 kHz.

description: We briefly present our version of noncommutative analysis over matrix algebras, the algebra of biquaternions ($\mathbb B$) in particular. We demonstrate that any $\mathbb B$-differentiable function gives rise to a null shear-free congruence (NSFC) on the $\mathbb B$-vector space $\mathbb{C}\bf M$ and on its Minkowski subspace $\bf M$. Making use of the Kerr--Penrose correspondence between NSFC and twistor functions, we obtain the general solution to the equations of $\mathbb B$-differentiability and demonstrate that the source of an NSFC is, generically, a world sheet of a string in $\mathbb {C}\bf M$. Any singular point, caustic of an NSFC, is located on the complex null cone of a point on the generating string. Further we describe symmetries and associated gauge and spinor fields, with two electromagnetic types among them. A number of familiar and novel examples of NSFC and their singular loci are described. Finally, we describe a conservative algebraic dynamics of a set of identical particles on the ``Unique Worldline'' and discuss the connections of the theory with the Feynman--Wheeler concept of ``One-Electron Universe''

description: We consider compressible pressureless fluid flows in Lagrangian coordinates in one space dimension. We assume that the fluid self-interacts through a force field generated by the fluid itself. We explain how this flow can be described by a differential inclusion on the space of transport maps, in particular when a sticky particle dynamics is assumed. We study a discrete particle approximation and we prove global existence and stability results for solutions of this system. In the particular case of the Euler-Poisson system in the attractive regime our approach yields an explicit representation formula for the solutions.

Doing business: students adding real business value in the Liverpool City Region via consultancy projects
Creators: name: Brown, Jan
Publisher: name: Student Experience Proceedings
Year: 2022

description: This presentation explores how students are adding real business value to organisations in the Liverpool City Region through their Level 6 business consultancy module. Based on a learning and teaching strategy of developing students knowing by apprehension a focus of doing business has been developed that puts students at the heart of the doing (Kolb 2015). By students working on real life projects that are unique to each student team or individual, students are provided with a supported opportunity to make the connection between the body of knowledge they have acquired through their undergraduate studies to concrete real life business problems (Schilpp 1949). As part of the strategy of the Liverpool Business School to develop business practice, this module has been developed and evolved over the past three years. In the academic year 2021/22 198 Level 6 students undertook 54 unique live projects from organisations in the Liverpool City Region and were supported by 1 of 10 bespoke business consultants who met with the student teams on a weekly basis. These projects were sourced by the LJMU Business Clinic and weekly progress was monitored to ensure adequate support was provided. A number of initiatives have been developed alongside Level 6 to develop and support students as they learn to do business. The key learning points are that using ecosystem thinking (Barile et al. 2016) has helped develop this module, many stakeholders have been included with the student voice being key to success. It is proposed that this type of thinking could be used to develop similar modules at LJMU. Reflections will also be provided on progress to date and details given of an emerging programme of research that is being developed to ensure that an appreciative inquiry approach to doing business is undertaken (Cooperrider & Srivastva 1987, 2017).

name: Michael-Phillips, Rob
Publisher: name: Student Experience Proceedings
Year: 2022

description: The session will focus on the cross-institutional change in approaches that may be needed to ensure appropriate and effective support for students with mental health concerns within LJMU. The Government has recently announced that it wants all HEIs to have achieved the Student Minds Mental Health Charter mark within the next 5 years. We will review internal data on disclosures, progress to date with the Office for Students Improving Student Pathways project, and the work needed to ensure that LJMU achieves the Student Minds Mental Health Charter mark. Moving to a whole institution approach will entail change at every level. We will explore what has been achieved to date, what change will be required over the interim period and where we hope to be in supporting students with mental health concerns. The session will update colleagues on the requirements of the Student Minds Charter and how this will impact on academic delivery as well as professional service delivery. It will also be a fact-finding exercise using the experiences of colleagues attending this session to inform the development of strategy and practice. In terms of university values, this session relates to all 4 values in that the work is student focused, ensuring inclusivity for those with mental health concerns, building community that supports all, and courageous as we will need to change the way we think about supporting students with mental health concerns.

'Learning is experience. Everything else is just information' (Albert Einstein): a closer look at LJMU's work-based learning experience objectives
Creators: name: Anderson, Danielle
Publisher: name: Student Experience Proceedings
Year: 2022

description: Work Based and Placement Learning is important (WBPL). It provides opportunities to bring academic theory and workplace practices together, resulting in increased student employability and sustainable development goals (ASET, 2013; Wall & Hindley, 2018). The importance of this learning experience should be considered in the same manner as other forms of learning, teaching, and assessment. To do it right, this learning needs to be delivered through meaningful partnerships between students, employers, and the university (QAA, 2018). Knowing that this experience will be transformational for our students, we have taken on the challenge of embedding an assessed work-based learning experience as a core feature of every undergraduate programme. Therefore, programmes will blend with, and offer, real-world experiences to students. Experiences that are authentic and structured, complementing learning journeys and enhancing skills and knowledge needed to succeed in the graduate workforce. Not all students are able to access the traditional ‘placement’ which is why adopting the work-based learning experience approach is important. This approach allows for alternative experiences to occur in curriculum that are inclusive and embrace our student community. Some of the questions you may have include: What does this mean in relation to the traditional placement? What might this work-based learning experience look like? How do we achieve this with large cohorts of students? How do we on-board external stakeholders/ employers to support this? We would like to help answer these questions and pose some additional ones! Student Futures are here to support, collaborate and co-create with our colleagues in faculties. This is a bold and courageous move we are making, committing to this. It will be our courage to act on this together that will give our students the courage and power they need to chase after the things that are important to them.

description: With the aim to assess the role of dense environments in galaxy interactions, properties we present an analysis of close galaxy pairs in groups and clusters, obtained from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7). We identified pairs that reside in groups by cross-correlating the total galaxy pair catalogue with the SDSS-DR7 group catalogue from Zapata et al. (2009). We classify pair galaxies according to the intensity of interaction. We analysed the effect of high density environments on different classes of galaxy-galaxy interactions and we have also studied the impact of the group global environment on pair galaxies. We find that galaxy pairs are more concentrated towards the group centres with respect to the other group galaxy members, and disturbed pairs show a preference to contain the brightest galaxy in the groups. The color-magnitude relation exhibits significant differences between pair galaxies and the control sample, consisting in color tails with a clear excess of extremely blue and red galaxies for merging systems. In addition, pair galaxies show a significant excess of young stellar populations with respect to galaxies in the control sample; this finding suggests that, in dense environments, strong interactions produce an important effect in modifying galaxy properties. We find that the fraction of star forming galaxies decreases toward the group centre; however, galaxy pairs show a more efficient star formation activity than galaxies without a close companion. We have also found that pair galaxies prefer groups with low density global environments with respect to galaxies of the corresponding control sample. Blue, young stellar population galaxies prefer groups within low density global environments.

description: This session will bring together academics and professional service staff from Student Recruitment and Outreach along with two Roma students who have recently completed their study with LJMU. Using students' voices at the heart, the session will take participants on a journey to discover how students from the most disadvantaged BAME group, Gypsy, Traveller, Roma, Showman and Boaters (GTRSB), decided to come to university. The session will span their initial experiences at the recruitment stage, such as what helped and hindered, through to their study experience, again exploring what interventions supported their study, what they could have benefited more from and what, if anything, acted as a barrier. Through an exposé of their highs and lows at each stage of their learning journey we hope to encourage debate and action to enable more students from marginalised communities to select university as a first and important choice for them. We hope to also encourage participants to look at support that is both innovative and inclusive, driven by current students' feedback. We will share how building relationships in the Roma communities in Liverpool has been key to collaborations that are sustainable and long lasting with the community on our doorstep. The session will draw on the expertise from Outreach and Recruitment who will share lessons that are transferable to other groups who, like Roma, might benefit from experience of HE. While speaking directly to two LJMU values: inclusive and community, engaging the students as co-presenters also speaks to having a student focus and being courageous. This reflects our key tenet to put our research participants' own lived experience, Roma, at the heart of the presentation.

All four allowed by symmetry even-parity phonons are identified. Phonon mode of B$_{1g}$ symmetry at 222 cm$^{-1}$, which is associated with the c-axis motion of Fe ions, is found to exhibit an anomalous frequency hardening at low temperatures, that signals non-vanishing electron-phonon coupling in the superconducting state and implies that the superconducting gap magnitude $2Δ_c < 27$meV.

Lessons from a pandemic: how can we make online learning more inclusive?
Creators: name: Chidlow, Stewart

Publisher: name: Student Experience Proceedings
Year: 2022

description: In the academic year 2018/19, 16.2% of home students declared a disability of some kind. This is an increase of 36% on the number of students who declared a disability in the academic year 2014/15 (Hubble and Bolton, 2020a). A survey conducted in 2018 also found that 21.5% of students had a current mental health diagnosis (Hubble and Bolton, 2020b). As many students with a disability do not feel able to disclose it due to the perceived stigma of doing so and because of difficulties in proving their disability (Toutain, 2016), the true number of students with a disability, particularly a hidden disability, studying at UK universities may be significantly higher. In this talk, we discuss the outcome of a curriculum enhancement project that sought to investigate students with hidden disabilities’ experience of online learning during the ongoing pandemic. Many research papers in the current literature point to the benefits and barriers that online learning can bring, and the project represented a first step in determining best practice in teaching and facilitating online learning. As many students with hidden disabilities, and indeed many students in general, find it hard to attend classes on a regular basis for a variety of reasons, this project also can inform how best to utilise VLEs, such as Canvas, to ensure that studying from a distance is a viable option for students when the need arises. In sharing this student-focused research, we will outline insights on what disabled students consider to be the key aspects of inclusive teaching and learning, to enable them to succeed and achieve their potential at this university.

description: In a multi objective setting, a portfolio manager's highly consequential decisions can benefit from assessing alternative forecasting models of stock index movement. The present investigation proposes a new approach to identify a set of nondominated neural network models for further selection by the decision maker. A new coevolution approach is proposed to simultaneously select the features and topology of neural networks (collectively referred to as neural architecture), where the features are viewed from a topological perspective as input neurons. Further, the coevolution is posed as a multicriteria problem to evolve sparse and efficacious neural architectures. The well known dominance and decomposition based multiobjective evolutionary algorithms are augmented with a nongeometric crossover operator to diversify and balance the search for neural architectures across conflicting criteria. Moreover, the coevolution is augmented to accommodate the data based implications of distinct market behaviors prior to and during the ongoing COVID 19 pandemic. A detailed comparative evaluation is carried out with the conventional sequential approach of feature selection followed by neural topology design, as well as a scalarized coevolution approach. The results on the NASDAQ index in pre and peri COVID time windows convincingly demonstrate that the proposed coevolution approach can evolve a set of nondominated neural forecasting models with better generalization capabilities.

Publisher: name: Student Experience Proceedings
Year: 2022

description: The iconic Littlewoods building on Edge Lane, Liverpool, is often referred to as the ‘Gateway to the City’. However, in spite of its prominence as a striking landmark, many are unaware of its amazing history. Beneath the bricks and mortar, the building reveals a fascinating tale about working life in the 20th Century. Completed in 1938, the site was originally used to house the Littlewoods Pools. John Moores and his brother Cecil were ahead of their time employing a workforce of mainly women. Over 30,000 employees worked for the company at its peak. The building was commandeered during WWII to make barrage balloons and Halifax bombers and they were one of the first companies in the UK to introduce IBM computers. This panel comprising of staff and student interns, will discuss how the team is collectively working with the community of former Littlewoods employees to create a digital archive and website in time for the centenary celebrations of 2023. We will discuss how student interns have been key in digitising and cataloguing the Littlewoods Archive held at National Football Museum (photographs, Pools coupons, letters and documents), along with vintage Mail Order catalogues donated to the project. We will also play clips from interviews with former employees that Film Studies students have recorded as part of the taught curriculum. Finally, we will discuss plans for forthcoming events involving the MA Immersive Media students creating content for the 100 year celebrations in the Anglican Cathedral and legacy artefact for the new Littlewoods Film Studios.

description: In the race towards quantum computing, the potential benefits of quantum neural networks (QNNs) have become increasingly apparent. However, Noisy Intermediate-Scale Quantum (NISQ) processors are prone to errors, which poses a significant challenge for the execution of complex algorithms or quantum machine learning. To ensure the quality and security of QNNs, it is crucial to explore the impact of noise on their performance. This paper provides a comprehensive analysis of the impact of noise on QNNs, examining the Mottonen state preparation algorithm under various noise models and studying the degradation of quantum states as they pass through multiple layers of QNNs. Additionally, the paper evaluates the effect of noise on the performance of pre-trained QNNs and highlights the challenges posed by noise models in quantum computing. The findings of this study have significant implications for the development of quantum software, emphasizing the importance of prioritizing stability and noise-correction measures when developing QNNs to ensure reliable and trustworthy results. This paper contributes to the growing body of literature on quantum computing and quantum machine learning, providing new insights into the impact of noise on QNNs and paving the way towards the development of more robust and efficient quantum algorithms.

description: We present a simple cellular automaton based model of decision making during evacuation. Evacuees have to choose between two different exit routes, resulting in a strategic decision making problem. Agents take their decisions based on utility functions, these can be revised as the evacuation proceeds, leading to complex interaction between individuals and to jamming transitions. The model also includes the possibility to communicate and exchange information with distant agents, information received may affect the decision of agents. We show that under a wider range of evacuation scenarios performance of the model system as a whole is optimal at an intermediate fraction of evacuees with access to communication.

Collaborating with our Women’s Academic Network to develop the new maternity policy: influence and impact upon future staff policy development
Creators: name: Mannion, Amanda

Publisher: name: Student Experience Proceedings
Year: 2022

description: This session is focused on celebrating the collaborative approach that was taken by Human Resources and the Women's Academic Network to develop staff policy and the support provided to staff members before, during and after maternity leave. This inclusive approach represented a change as to how, as a University, we have adapted our policies to reflect the feedback from our staff community. This approach was successful due to the courage and honesty shown by our staff in sharing their maternity experience at the university. The network came together as a community to share, inform and support the recommendations for change. As an institution it was recognised that by committing to enhancing pay and leave and providing clearer, concise advice to staff, it would enable them to spend quality time with their family whilst also ensuring that they felt supported by, and connected to, the university. This approach also supports the University’s journey to become an employer of choice and therefore attract and retain the best talent for the institution. As our staff feel supported and we attract and retain the best talent this also provides an enhanced student experience. The outcome has been well received and the approach has led to further work on a breastfeeding initiative, which is being developed for our students and staff, and in further development work on sabbatical leave provoked by post maternity considerations. This inclusive approach of involving the staff community through our Networks in the development of policies that impact upon them is one that we will be looking to embrace within Human Resources.

Developing hybrid work-based learning placements to transform the university experience
Creators: name: Johnston, Wendy
name: Smith, Nicola
Publisher: name: Student Experience Proceedings
Year: 2022

description: The current economic climate dictates that students engage within the world of work to help them gain the knowledge, skills and experience needed to prepare them for their graduate careers (Huddleston and Stanley 2012). This is supported by The LJMU Student Employability, Enterprise and Employment Strategy 2019-2023, which states undergraduate students should undertake a meaningful work placement or Work-Based Learning (WBL) experience as part of their degree. BSc Nutrition students are required to complete four weeks WBL with an external provider. The COVID pandemic meant in-situ placements were suspended. Authentic virtual placement experiences, which enabled an equitable experiential learning experience for all students, therefore had to be provided. During the pandemic, students worked virtually with external partners, engaged in projects and explored future career options. Virtual placements added real value creating a modern student experience, enabled students to develop transferable skills including adaptability and digitally literacy, tailored in real-life opportunities and highlighted real-world applications of knowledge and skills. Changes from in-situ placements to virtual placements were successful and mirrored opportunities and constraints of a physical workplace. We recognised the positive outcomes for student employability, viewing the impact of COVID as an opportunity to re-evaluate our WBL offering. Building on the success of virtual placements and the relaxation of COVID restrictions, we have moved to student-focused hybrid placements designed in conjunction with all four LJMU values to provide a transformational student experience. Embracing LJMU’s vision, values and civic agenda and working in active partnership locally, nationally and globally, hybrid placements offer authentic, personalised student experiences outside the classroom. Hybrid placements allow students to learn actively, to work proactively, to drive innovation and to effect change which enhances the students’ academic and intellectual journey whilst supporting future aspirations. This will be presented collectively by Faculty staff, Professional Services staff and Students.

The effects of ionizing radiation on p53 and p21CIP1
Creators: name: Blough, Michael Donald
Publisher: name: University of Calgary

description: Bibliography: p 160-187
description: Some pages are in colour.
description: In response to ionizing radiation (IR) cells undergo cell cycle arrest and/or apoptosis. These responses are mediated by the tumor suppressor protein p53, and are thought to be essential for maintaining genomic stability and integrity. Although it has long been assumed that the mechanisms by which p53 regulates these processes were ubiquitous, the advent of new experimental techniques and technologies has begun to demonstrate variations. As such, the purpose of this thesis was to re-investigate the effects of IR on p53, and one of its key downstream targets, the cyclin dependent kinase inhibitor p21 CIPl, with some of the more recent observations in mind. The results presented within this thesis contradict much of the previous data on the effects of IR on p53 and p21 CIPl; it is demonstrated that p53 activity and protein levels are unaltered in response to IR, and that p21 ClPl exists in a heterogeneous population of isoforms. Most importantly, it is shown that p21 CIPl may be differentially modified in response to IR. Based on the results contained within this thesis a theoretical model is proposed by which p53/p21ClPl mediated cell cycle arrest occurs in response to IR.

Optometrists refer patients but in many cases no referral outcome letter/reply is received. In the absence of a reply, patients often need to be re-referred unnecessarily, potentially increasing the number of other patients who lose sight whilst waiting on extensive hospital waiting lists. Sight loss could be irreversible. To increase/optimise the number of referral reply letters from secondary care it is necessary to understand what factors influence the optometric referral reply rate. Methods: Ethics approval was obtained for a multiphase sequential mixed methods primary research study (qual - QUAN - qual). Documentary analysis of 349 patient referral records from three optometric practice modalities (domiciliary practice, an independently owned group and an optical corporate chain) were quantitatively investigated using IBM SPSS Statistics 25 software. One-on-one, semi-structured interviews were used to obtain the views of thirteen stakeholders These were qualitatively analysed using NVivo 12 software. Results: A referral reply rate of 11.2% was calculated. Factors influencing the optometric referral reply rate included; technology, the GP, optometrists’ utility to and utility of the NHS, patient mobilisation and individual behavioural differences. Conclusion: Community optometrists can and should improve the referral reply rate by responding to the factors identified.

description: The roles of critical valence fluctuations of Ce and Yb are discussed as a key origin of several anomalies observed in Ce- and Yb-based heavy fermion systems. Recent development of the theory has revealed that a magnetic field is an efficient control parameter to induce the critical end point of the first-order valence transition. Metamagnetism and non-Fermi liquid behavior caused by this mechanism are discussed by comparing favorably with CeIrIn5, YbAgCu4, and YbIr2Zn20. The interplay of the magnetic order and valence fluctuations offers a key concept for understanding Ce- and Yb-based systems. It is shown that suppression of the magnetic order by enhanced valence fluctuations gives rise to the coincidence of the magnetic-transition point and valence-crossover point at absolute zero as a function of pressure or magnetic field. The interplay is shown to resolve the outstanding puzzle in CeRhIn5 in a unified way. The broader applicability of this newly clarified mechanism is discussed by surveying promising materials such as YbAuCu4, beta-YbAlB4, and YbRh2Si2.

Towards Explainable Strategy Templates using NLP Transformers

description: This paper bridges the gap between mathematical heuristic strategies learned from Deep Reinforcement Learning (DRL) in automated agent negotiation, and comprehensible, natural language explanations. Our aim is to make these strategies more accessible to non-experts. By leveraging traditional Natural Language Processing (NLP) techniques and Large Language Models (LLMs) equipped with Transformers, we outline how parts of DRL strategies composed of parts within strategy templates can be transformed into user-friendly, human-like English narratives. To achieve this, we present a top-level algorithm that involves parsing mathematical expressions of strategy templates, semantically interpreting variables and structures, generating rule-based primary explanations, and utilizing a Generative Pre-trained Transformer (GPT) model to refine and contextualize these explanations. Subsequent customization for varied audiences and meticulous validation processes in an example illustrate the applicability and potential of this approach.
Examining wasta from a sensemaking perspective: comparing public and private universities in Saudi Arabia

description: Wasta is a social practice that dates back to tribal times in Saudi Arabia before the establishment of the country in 1744 and involves reliance on personal relationships and connections to get things done either directly or through a third party. This thesis examines individual experiences of Wasta in the context of Saudi Arabia and Saudi universities more specifically. To investigate the complexities surrounding the phenomenon, the thesis adopts a multiple level perspective drawing on Bourdieu's approach to social and cultural capital, Weick and others' framing of sensemaking, D'Iribarne's approach to national culture and scholarship on organizational culture. This multi-level and multifaceted approach make it possible to analyze how individuals negotiate institutional norms when encountering requests for Wasta. The thesis applies qualitive methods, including a comparative case study of two public universities and two private universities, and forty interviews with managers, academics, and administrative staff from all four targeted universities. On this basis, the study compares interpretations of Wasta and Wasta practices following the changes brought about by the Saudi Government's Vision 2030 at national and organizational levels. In this regard, attention is focused on the Vision's anti-corruption campaign, which involved a privatization program targeting several sectors, including higher education. At the macro level, the study examines the origins, norms and practices associated with Wasta as well as the impact of the Saudi government's reforms and Islamic teachings on institutions and on interpretations of Wasta. At the meso level, attention is given to the case study organizations and sub-cultures within each, made up by managers, academic and administrative staff. At this level and also at the micro level, consideration is given to the role played by social, cultural, and symbolic capital in the practice and experience of Wasta. This study found that methods applied by universities ostensibly to eradicate Wasta, such as privatization, centralization, and automated systems, were not sufficient. Accordingly, the study found that a more effective approach would be for universities to adopt formal policies to outlaw Wasta practices. This thesis concludes that tensions and to some extent conflict between institutional frames, cultural norms and legal consequences relating to Wasta require continuous negotiation by university staff in different occupational subcultures to identify which institutional norms to follow when encountering Wasta requests.

Emission of correlated photon pairs from superluminal perturbations in dispersive media

description: We develop a perturbative theory that describes a superluminal refractive perturbation propagating in a dispersive medium and the subsequent excitation of the quantum vacuum zero-point fluctuations. We find a process similar to the anomalous Doppler effect: photons are emitted in correlated pairs and mainly within a Cerenkov-like cone, one on the forward and the other in backward directions. The number of photon pairs emitted from the perturbation increases strongly with the degree of superluminality and under realizable experimental conditions, it can reach up to ~0.01 photons per pulse. Moreover, it is in principle possible to engineer the host medium so as to modify the effective group refractive index. In the presence of "fast light" media, e.g. a with group index smaller than unity, a further ~10x enhancement may be achieved and the photon emission spectrum is characterized by two sharp peaks that, in future experiments would clearly identify the correlated emission of photon pairs.

Embracing the voices of people with autism: a participatory study
Creators: name: Coney, Karen

Publisher: name: Student Experience Proceedings
Year: 2022

description: A recent study of the destinations of graduates found that of all disabled graduates, autistic individuals are least likely to be employed (Allen & Coney 2021). Unfortunately, these findings are widely recognised in literature (Vincent 2020, Remington & Pellicano 2019). The disappointing outcomes for autistic graduates in the UK highlight the way in which these individuals are in danger of being marginalised. In this session, a careers practitioner and a student will outline the participatory activities and study conducted here at LJMU which explored how to provide effective careers and employability support for autistic students. Understanding that in order to create such support, it would be important to involve the intended recipients, the careers practitioner recruited volunteers to act as consultants. These autistic student consultants were engaged in all stages of the project, from analysing an initial survey of all autistic students in the University, to co-designing the careers-related activities, to evaluating the effectiveness of these activities. This participatory method not only provided the careers practitioner with real insights into what provision to include in the future, but also had a transformational impact on some of the student consultants and others involved. In addition to the creation of a community, there are signs of a ‘ripple effect’ within the university, as those students and staff involved continue to seek to make courageous and positive changes for the sake of autistic students and disabled students as a whole.
