Staff and students co-creating curricula in UK higher education: exploring process and evidencing value

Student engagement in learning and teaching is receiving a growing level of interest from policy makers, researchers, and practitioners. This includes opportunities for staff and students to co-create curricula, yet there are few examples within current literature which describe and critique this form of staff-student collaboration (Bovill (2013a), Healey et al (2014), Cook-Sather et al (2014). The competing agendas of neoliberalism and critical, radical pedagogies influence the policy and practice of staff and students co-creating curricula and, consequently, attempt to appropriate the purpose of it in different ways. Using case-based research methodology, my study presents analysis of staff and students co-creating curricula within seven universities. This includes 17 examples of practice across 14 disciplines. Using an inductive approach, I have examined issues relating to definitions of practice, conceptualisations of curricula, perceptions of value, and the relationship between practice and institutional strategy. I draw upon an interdisciplinary body of literature to provide the conceptual foundations for my research. This has been necessary to address the complexity of practice and includes literature relating to student engagement in learning and teaching, conceptual models of curriculum in higher education, approaches to evidencing value and impact, and critical theory and radical pedagogies. The study makes specific contributions to the wider scholarly debate by highlighting the importance of dialogue and conversational scholarship as well as identifying with participants what matters as well as what works as a means to evidence the value of collaborations. It also presents evidence of a new model of co-creating curricula and additional approaches to conceptualising curricula to facilitate collaboration. Analysis of macro and micro level data shows enactment of dialogic pedagogies within contexts of technical-rational strategy formation and implementation.

Investigating disease persistence in host vector systems: dengue as a case study

The investigation of pathogen persistence in vector-borne diseases is important in different ecological and epidemiological contexts. In this thesis, I have developed deterministic and stochastic models to help investigating the pathogen persistence in host-vector systems by using efficient modelling paradigms. A general introduction with aims and objectives of the studies conducted in the thesis are provided in Chapter 1. The mathematical treatment of models used in the thesis is provided in Chapter 2 where the models are found locally asymptotically stable. The models used in the rest of the thesis are based on either the same or similar mathematical structure studied in this chapter. After that, there are three different experiments that are conducted in this thesis to study the pathogen persistence. In Chapter 3, I characterize pathogen persistence in terms of the Critical Community Size (CCS) and find its relationship with the model parameters. In this study, the stochastic versions of two epidemiologically different host-vector models are used for estimating CCS. I note that the model parameters and their algebraic combination, in addition to the seroprevalence level of the host population, can be used to quantify CCS. The study undertaken in Chapter 4 is used to estimate pathogen persistence using both deterministic and stochastic versions of a model with seasonal birth rate of the vectors. Through stochastic simulations we investigate the pattern of epidemics after the introduction of an infectious individual at different times of the year. The results show that the disease dynamics are altered by the seasonal variation. The higher levels of pre-existing seroprevalence reduces the probability of invasion of dengue. In Chapter 5, I considered two alternate ways to represent the dynamics of a host-vector model. Both of the approximate models are investigated for the parameter regions where the approximation fails to hold. Moreover, three metrics are used to compare them with the Full model. In addition to the computational benefits, these approximations are used to investigate to what degree the inclusion of the vector population in the dynamics of the system is important. Finally, in Chapter 6, I present the summary of studies undertaken and possible extensions for the future work.
