• Safeguarding children in the National Health Service: A study of government policy development and its implementation by strategic health managers in the North West

      de Sousa, Eustace (University of ChesterNHS North West, 2012-10)
      There are approximately 1.6 million children and young people under the age of 18 living in the North West of England (NHS NW, June 2011). Each of them is entitled under international and national laws to protection from harm. This research sets out the context in which England‟s national policy for safeguarding children is developed and how this is implemented in National Health Services (NHS) across the North West. The context setting of legislation is important because of the cultural backdrop this sets for strategic health managers. These managers are responsible for ensuring local health services satisfy national and local requirements, and are keeping children safe. The timing of this research is particularly relevant because of the current reforms the NHS is undergoing, which means that from April 2013 new commissioning arrangements for health services will be in place. A conceptual framework sets out an ecological framework in which policy makers and these managers operate, highlighting key factors which influence decisions. Although much academic and action research has been undertaken in this field, very little has been done in respect of this strategic group of health service managers. This original research explores, through a quantative approach, some of the key influences on these managers. The research findings identify the powerful effect of public opinion on the managers, and that the influence of policy and prioritisation is strongest when this is applied locally. This is important when one considers the Government‟s commitment to local organisations taking greater responsibility for identifying local priorities rather than being set centrally. Finally, recommendations for utilising the learning from the research are proposed for the researcher‟s organisation, the Strategic Health Authority (SHA) for the North West.
    • The School Improvement Partner a ‘critical friend’ to strategic leaders in a Local Authority’s schools?

      Killen, Malik (University of Chester, 2009-06)
      This research project begins to address the gap in knowledge about the role of the School Improvement Partner. It considers the links between the external consultant, ‘critical friend’ and the School Improvement Partner. The findings of this research indicate that the School Improvement Partner role can be akin to a “critical friend” and that there is a match between factors of successful consultancy. The paper concludes suggesting further research to expand the knowledge base and inform the development of the School Improvement Partner role.
    • A secondary sisterhood: Revisioning nineteenth-century homosocial bonds between women

      Siddle, Yvonne; Joughin, Frances E. (University of Chester, 2014)
      This dissertation explores the ways in which revisionary fiction engages with understanding that nineteenth-century gender constructs negatively impacted women’s homosocial bonds. It examines three different periods throughout the nineteenth-century to reflect upon the ways in which revisionary texts engage with changing cultural ideologies throughout the period. Beginning with Austen’s Pride and Prejudice (1813), and comparing this to the text and television adaptation Death Comes to Pemberley (2011, 2013), Chapter one examines the ways in which James’s text interprets Austen’s potentially proto-feminist comment on female homosocialism. It draws upon the ways in which the ‘Jane Austen’ brand has potentially influenced James’s text, but also reflects on how the brand continues to move with changing modern cultures through recent representations such as the internet comic, Manfeels Park. Chapter two takes a leap forward into the mid- to late-Victorian period and explores the ways in which lesbian potential may have also been affected by the secondary conditions of women’s homosocial bonds. It examines how Sarah Waters’ neo-Victorian texts Fingersmith and Tipping the Velvet write over the dearth of lesbian representation in canonical literature of the period. Chapter three examines representation of the New Woman in The Odd Women (1893), the film, Hysteria (2011) and The Crimson Petal and the White (2002). It compares the ways in which her attempt to carve out a new kind of female homosocialism has a unique link to the present because of the New Woman’s ‘modern’ approach. It examines the representation of her as an individual in revisionary texts, compared to her as part of a collective in The Odd Women, and how this makes suggestions about the state of modern feminism.
    • Self-Respect and Prejudice: An Enquiry into Self-Respect as a predictor of Prejudice and Discrimination Towards Sufferers of Eating Disorders

      Clucas, Claudine; Rodrigues Bezerra, Marcus (University of Chester, 2017-09)
      The relationship between Self-Respect (specifically Recognition Self-Respect and Appraisal Self-Respect) and Prejudice has not yet been fully investigated, and there are indications that they relate to Prejudice through other components of Self-concept, such as Empathy and Unconditional Respect. To establish the dynamics of this relationship participants (N = 95, 54 females and 41 males) from an opportunity sample of students and members of the public from Cheshire County participated in a Cross-sectional survey study. Different scales were employed measuring: Recognition Self-Respect, Appraisal Self-Respect, Unconditional Respect, Self-Esteem, Empathy Scale, and Paid Respect Scale. Appraisal Self-Respect was found to be a significant predictor of Prejudice, and this relationship was mediated bf Empathic-Concern Empathy. Recognition Self-Respect was not found to be a significant predictor of Prejudice, after adjusting for global Self-Esteem. The discrepancy in findings within the concept of Self-Respect may be a reflexion of the complexity in the components that constitute Self-Respect, and of the dynamic manner, in which Respect and Self-Respect relate as a continuum.
    • Six sigma as a facet of change management at PCN Pharmaceuticals

      Page, Steve; Hughes, Clare (University of Chester, 2010-06)
      This study looks at the six sigma training program that has been introduced within PCN Pharmaceuticals as a facet of change management. It examines the perceptions of a sample group on the subject of both a six sigma program and the management of change through the use of a questionnaire. This methodology is utilised in order to understand the perceptions around the implementation of the six sigma program after the initial roll-out. The research concludes that PCN needs to gain an understanding as to why a number of six sigma projects have not yet been completed despite attendance at six sigma training by site employees. The research findings reveal that there is not enough communication and support around the six sigma program, especially from the PCN management team. This communication also needs to reinforce the concept of change being central to the six sigma process. The research finds that the drivers for change within PCN are understood, along with the strategic goals and objectives. Furthermore, the research finds that an effective infrastructure needs to be put in place at PCN to support the six sigma program in order that it may be successful.

    • Social and cultural construction of obesity among Pakistani Muslim women in North West England

      Ellahi, Basma; Cox, Peter; Ludwig, Alison F. (University of Liverpool (University of Chester), 2012-04)
      Higher rates of obesity, Type 2 diabetes and coronary heart disease are observed in British Pakistani women compared to the general UK population. This qualitative research explored the links between the participant’s understanding of health risks related to obesity, body image and dietary patterns in a cohort of first- and second-generation Pakistani women, living in Greater Manchester, England. Pakistani women act as gatekeepers to family nutrition and health. The research aims to inform promotion strategies, focusing on healthier changes, and to create increased levels of awareness of the strategies. Beyond South Asian [SA] languages, effective and ethnically appropriate approaches are essential to reach these goals. Research outcomes can no longer just be interesting or show potential, as they ought to contribute to improving women’s health and advice public health professionals when making relevant recommendations. Qualitative techniques, using focus groups and one-to-one interviews, with 55 women, were recruited from the Pakistani community via snowballing and cold calling at community and resource centres. The participants were either active in their local communities or were deemed “hard to reach” in relation to accessibility. The interviews were conducted in the participants’ homes or at the venues. Third-person fictitious vignettes were used to stimulate and promote discussion. A series of vignettes were intended to resonate with the participant’s own lives. The interviews were audio-recorded, transcribed then analysed. One researcher as a community insider and the other as an outsider, along with sociological analysis, reflected upon then coded the data. Using ethnography and an interpretive, phenomenological framework, allowed for data description and interpretation of an emerging understanding. The rich data uncovered issues relating to faith, family and broader socio-cultural influences, all of which had an impact on daily life and in particular to food choices. Despite an acknowledgement of obesity in themselves and around them, there appeared to be a lack of awareness linking obesity to health outcomes. The participants in both generations turned to and, in part, relied upon both traditional food and western health beliefs. As an outcome of the data analysis, a multi-directional theoretical model was developed specifically for this group of women in Manchester, called the Health Action Transition (HAT) model. The HAT model is intended to be used as a working tool in a clinical setting to aid in understanding of the Pakistani women’s socio-cultural structures and to provide a framework for recommendations relating to health promotion for these women.
    • Social Class and the Therapeutic Relationship: The Client's Perspective: To what extent do perceived differences in social class between client and therapist impact upon the therapeutic relationship? A qualitative study using a questionnaire survey.

      Trott, Alison (University of Chester, 2016-05)
      The inequalities in society are often mirrored within the therapeutic relationship, particularly for those therapists working in the NHS or for charitable organisations, where therapists are often middle-class and clients working or lower-class. The aim of this research was to explore, using a questionnaire survey, clients’ perceptions of the impact of social class and whether, and if so how, perceived social class disparities impacted the therapeutic relationship. Forty-five completed questionnaires fulfilling the inclusion criteria were returned. Using a quasiphenomenological approach and Thematic Analysis, four primary themes were identified: 1) Perceptions of own social class; 2) Social class as a facilitative aspect of therapy; 3) Negative impact of social class on therapy; and 4) Clients perceptions of their therapeutic relationship. Regardless of social status of the client or their therapist, social class similarities and disparities were found to both help and hinder the therapeutic relationship. Despite many respondents believing social class to be an irrelevant factor within their therapeutic relationship, this study illustrates that social class was a silent but powerful force affecting clients’ feelings of equality, which were often ignored. Though many respondents felt intuitively understood and experienced a more effective therapeutic alliance when perceiving client/therapist social class similarity, there was a danger that therapists could assume too much and/or collude with their clients. The findings also show that where there was social class disparity, though the quality of the relationship, and in particular empathy, were found to be crucial, the explicit recognition and acknowledgement of this disparity were shown to have a positive impact on the client, improving equality, increasing rapport and enabling greater psychological growth. For a client to take full benefit from therapy therapists must recognise the importance of social class and classism and the impact these have upon the therapeutic relationship, and be prepared to attend to these dynamics when appropriate.
    • The social influences on the development of the self

      Yilmaz, Mandy; Robinson, Joanne (University of Chester, 2013)
      Self-awareness is defined as one’s ability to differentiate themselves from others, and is influenced by early life experiences (Fonagy, Gergely, & Jurist, 2003). Some children develop self-awareness earlier than others (e.g., Amsterdam, 1972; Lewis & Ramsey, 2004), however, the developmental field has largely neglected to consider how parents may influence the attainment of self-awareness. The present study aimed to explore how typical mother-child interactions might influence infant self-awareness and whether there was a link between object awareness and body self-awareness. In addition, it was predicted that there would be an association between infant mirror-recognition and body self-awareness as found in previous research (Moore, Mealiea, Garon, & Povinelli, 2007). Infants aged between 15-18 months (N=12) were recruited to test their body self-awareness and self-recognition by use of a toy shopping trolley task and mirror-recognition test respectively. The original hypothesis was not supported; there was no association found between infant mirror-recognition and body self-awareness. Additionally, the observed mother-child interactions did not influence infant self-awareness and there were no links found between object awareness and body self-awareness. The limitations of the study included the small sample size and the lack of longitudinal data. Implications for future research include a larger number of participants, together with collecting longitudinal and cross-cultural data to examine any cultural differences in infant self-awareness.
    • The 'social-realist' phase in the painting of Luke Fildes, Hubert Herkomer, and Frank Holl: The making and unmaking of a sub-genre

      Watson, Peter J. (University of Chester, 2007-10)
      This dissertation discusses three Victorian artists, Luke Fildes, Hubert Herkomer, and Frank Holl, who emerged partly or mainly through their drawinsg for the Graphic magazine. All used images of the poor created for this work as motifs for major paintings which have come to be called 'social-realist', and all went on to devote their careers largely to portraiture. Yet to group them this way, and to apply the 'social-realist' label can be deeply misleading, firstly because they never worked together as a 'movement' with an ideology or manifesto, secondly because the label has more radical or socially-critical connotations as applied to other movements of that name in the twentieth century, and thirdly because it was applied only retrospectively in the twentieth century in the wake of those movements, implying ideological comparability.
    • A sociological analysis of who volunteers are, and why they volunteer in sport and non-sport organisations

      Bloyce, Daniel; Mead, Rebecca (University of Chester, 2009)
      The aim of this study was to explore, from a figurational perspective, 1) the similarities and differences between individuals who volunteer in a sporting environment and those that volunteer in other volunteering environments, and 2) the shared and distinct issues that might exist within each area of the voluntary sector. There is a reasonable amount of literature on volunteering generally, including some from a sociological perspective; however, there is much less available concerning volunteering in a sporting context. Furthermore, voluntary Sports Organisations are a substantial provider of services and opportunities for participation and central government include goals of increasing sport participation through them (Game Plan, 2002). The study was based in the county of Flintshire in North Wales. Using a combination of research approaches both questionnaires and interviews were used. The questionnaires aimed to produce demographic information about both sports and non-sports volunteers. For the most part, both groups of volunteers were above the age of 45 and well educated. Sports volunteers were more likely to be employed in full time roles. Non-sports volunteers were more likely to be female, where as sports volunteers were more likely to be male. Individuals from both groups were likely to undertake more than one role for their organisation. The purpose of conducting interviews was to provide a more in depth analysis of the views and perceptions of volunteers themselves, that is, what it is that they do and think about volunteering. For non-sports volunteers, their primary motivation was helping others, although when explored more closely, this was also aligned to the satisfaction gained from helping others often coupled with a number of other internal functions, such as, the socialising aspects and gaining a sense of purpose. For sports volunteers their motivation was very much aligned with their love of sport itself. This study found that for the sports volunteers interviewed, their voluntary activity was a way of them engaging with their sports. For some it was a necessary function in order to keep the club they played for going, for others it was a way of maintaining their connection with the sport. Non-sports volunteers made a proactive choice to volunteer where as, for the most part sports volunteers gradually became involved in the running of the organisation as a consequence of their membership. Both groups considered frustrations with their voluntary activity, for the most part non-sports volunteers discuss fund raising and bureaucracy. Sports volunteers frustrations were around a lack of commitment from others and difficulty in recruiting new members as well as funding. I have argued that it is the networks of figurations in which individuals are involved that influences behaviour. These networks have both constraining and enabling elements that either support or limit volunteering behaviour. Further, these networks influence the types of activity one in which one engages. The conclusions from this study have implications for both the methodology and future research questions. What is clear is that there is much more research to be undertaken reflecting on volunteering in sport and from a sociological perspective.
    • A sociological investigation in to the dynamic power balance between the Football League and Football Association: Using the Football League Cup as a window for exploration

      Bloyce, Daniel; Hopkins, Gareth (University of ChesterUniversity of Chester, 2008)
      This thesis suggests that the Football League Cup was introduced as part of a wider social policy to challenge the Football Association’s position in power. Therefore, testing the figurational perspective and, using the Football League Cup as a window for exploration, this thesis has investigated the dynamic power relationship between the Football Association and Football League and, later, on to the emerging relationship with international football governing bodies – FIFA and UEFA. Therefore, this investigation has; (1) Traced the development, sociologically, of the Football League Cup and; (2) investigated the fluctuating relationship between differing football governing bodies. Such analysis is unique in that academics have failed to recognise the sociological significance in that football is the only sport in England governed by two separate authorities and, as such, this is the first dedicated investigation of its kind. Furthermore, this is the first sociological study to examine England’s ‘secondary’ football cup competition – the Football League Cup. Documentary analysis was the chosen research method for investigation. Specifically, to investigate the controversy surrounding the Football League Cup, newspaper analysis was conducted using two online resources – The Times Digital Archive and NewsBank Info Web. To help understand the shifting power balance between the FA and Football League, research took place at the FA headquarters in Soho, London – here, a systematic analysis of FA minutes and literature within the FA library took place. This thesis has identified that the Football League Cup was introduced as part of an ulterior motive to challenge the position of the Football Association. In fact, this dissertation highlights that the FA have been in conflict with other associations since before their advent in 1863. Furthermore, this investigation has contradicted the claim, made by some, that the Football League Cup is ‘pointless’ or ‘worthless’. In fact, this investigation has found that the Football League cup has proven to be extremely useful to the lesser sides that have a second opportunity to draw a ‘bigger’ club (as they already have this opportunity in the FA Cup) and, also, the tournament is an important asset to the Football League who were able to use the competition as a ‘tool’ for negotiation. Nevertheless, although the FA has been challenged throughout their existence, the organisation remains the number one authority for English professional football, formally speaking.

    • Soldier Endurance and the First World War Trench Press

      Craggs, Neal (University of Chester, 2018-09-19)
      Soldiers in the First World War, began publishing trench journals shortly after the German and Allied Armies entrenched along the Western Front. Although, they were not limited to the Western Front, and by the end of the war were present in many theatres. They were of varying quality, sometimes printed, sometimes hand-drawn. They constitute a unique collection of literature, poetry, and journalism, and give voice to a culture that, however briefly, emerged in the trenches of the Great War, and vanished with the signing of peace. These journal provide exceptional insight into the lives and thoughts of the inhabitants of the trenches. They are by no means a flawless historical source. They were subject to censorship, both official and self-imposed; the soldiers who wrote them were undoubtedly, in some ways, prejudiced and ignorant; they were written for an audience whose interests were particular and restrictive. Therefore, the soldier newspapers do not provide a comprehensive or uncomplicated view into the First World War, or the trench system. Nevertheless, they do represent an independent, unique, and under researched source of trench literature. This dissertation will comprise a limited study of a selection of trench journals, with the intention of analysing the ways in which these newspapers may have been beneficial to the soldier in the trenches. This analysis will be undertaken with a view to ascertaining ways in which soldiers were able to endure the harshness of trench warfare for years. It will consist of four chapters, the first being a source analysis and literature review combined, and the next three chapters will look into the ways that the trench journals present soldiers' perceptions of the trenches, the home front, and the enemy, respectively.
    • “Some are gay, some are straight, no one actually cares as long as you’re there to play hockey”: Women’s field hockey players’ engagement with sexual identity discourses

      McEvilly, Nollaig; Whitehouse, Lauren E (University of Chester, 2019-02-13)
      This research investigates the discourses that have impacted recreational women’s hockey players’ perspectives and experiences surrounding sexual identity. Furthermore, the participants’ engagement with sexual identity discourses and through what discursive practices and disciplinary techniques sexual identities became dominant or alternative is examined. The experiences of and towards non-heterosexual sportspeople is a developing area of research, though little research focuses on recreational level sport that is not identified as a ‘gay sport space’. This study contributes to sexuality and sport research by investigating a recreational women’s team which is not restricted to the ‘gay sport space’ label to develop understandings of the dynamics and complexities that sexual identity discourses have on both heterosexual and non-heterosexual sportspeople. A poststructural, Foucaultian theoretical framework underpins this study with the utilisation of Foucault’s work on discourses, techniques of power and the technologies of the self. Data is generated from semi-structured interviews with seven hockey players, who discuss their experiences regarding sexual identity at Castle Ladies Hockey Club. By analysing the participants’ talk through discourse analysis, discourses of acceptance and inclusivity towards non-heterosexual identities are found. Firstly, non-heterosexual identities are regarded as ‘normal’, secondly, the focus was on if the player was a good team player rather than sexual identity, and thirdly, there was an increased acceptance of sexual fluidity leading to decreased tolerance towards homophobia. This research highlights that players engage with multiple discourses associated with sexual identity, often complexly. This raises questions surrounding the dominance of heteronormativity, as non-heterosexual identities are not presented as marginal.
    • South Asian women’s views and experiences of weight, diet and physical activity changes before, during and after pregnancy

      Mellor, Duane; Brignall, Kathryn (University of Chester, 2013-09)
      Being pregnant and becoming a parent is a crucial time when lifestyle behaviours may change and weight gain and retention may occur. This point in the life cycle presents a critical opportunity to advise and support South Asian women, who have a high risk of type 2 diabetes mellitus at lower BMIs, in order to reduce health inequalities, prevent ill health and improve health outcomes in this group. However, interventions necessitate an understanding of the factors affecting weight during this time, yet, to date, there is a lack of evidence in this field. The retrospective exploration of South Asian women’s views and experiences of weight, diet and physical activity changes before, during and after pregnancy and the possible implications of these changes for healthcare services and interventions. Ten South Asian women with a child between 7-24 months of age, living in Bolton, Greater Manchester, participated in a semi-structured, one-to-one interview. The interviews developed a detailed insight into weight, diet and physical activity changes before, during and after pregnancy and the factors impacting on these. Transcripts were analysed using phenomenological approaches. Respondent validation was used to confirm the findings. Interviews primarily took place in participants’ homes, although health, community and children’s centres were also utilised. The findings helped to develop an understanding of the factors influencing weight, diet and physical activity changes before, during and after pregnancy in a group of South Asian women. The findings suggested that views and experiences, and hence motivators and barriers, of change are not static across pregnancy and the post-partum period. Prior to conception, women felt in control of their weight and therefore following a healthy lifestyle was of little importance. During pregnancy, healthy behaviours were difficult to make and sustain and weight gain was perceived to be uncontrollable. The post-partum period was an important time to make positive behaviour changes but women also faced significant barriers to change during this time, particularly when breastfeeding, and South Asian women appeared to face additional cultural barriers. A lack of advice and support from healthcare professionals during and after pregnancy was also reported and consequently important opportunities to encourage positive behaviour change and overcome barriers to change in this group were missed. Conclusion: Maternity services which aim to advise and support South Asian women in the areas of weight, diet and physical activity before, during and after pregnancy must consider the factors influencing them during this time.
    • Space creation dynamics in basketball: A comparison between British and Spanish leagues

      Worsfold, Paul R.; Crum, Phillip (University of Chester, 2013-09-30)
      The most important states for the basketball offence are the ones that produce a rupture in the defence; these are referred to as space creation dynamics (SCD). The British League (BBL) currently falls out of the top 20 domestic leagues in Europe. Spanish Liga ACB is currently ranked the highest league outside of North America. The purpose of this study is to compare the SCD classes used between the BBL and the Liga ACB. The SCD classes are Space Creation with Ball Dribbled, Space Creation with Ball not Dribbled, Perimeter Isolation, Post Isolation, Space Creation Without Ball, On Ball Screen and Out of Ball Screen. Each SCD class occurrence was recorded on a location grid. Twelve games from both the BBL and the Liga ACB were analysed. A total of 3793 possessions were analysed. Intra- and inter-rater reliability was performed using the Cooper et al (2007) method. The results identified several differences between the SCD classes used between the BBL and Liga ACB; Space Created ball Dribbled, On the ball Screen and Off the Ball Screen in the percentage of usage between the BBL and the Liga ACB. A statistical difference was found between the two leagues. BBL used 31.6% on space created with ball dribbled compared to Liga ACB 18.5%. Liga ACB used 19.5% of possessions using on the ball screen compared to BBL 7.5%. Liga ACB used 11.8% with out of ball screen compared to BBLs 5.4%. The practical implications of this study should be primarily aimed at the coaches and then secondly aimed at the players. Developing the BBL to use multiple solutions to create a rupture in the defence would lead to a more developed league which could mimic the tactical play of the Liga ACB.
    • Stability of alignment during extended hold times in the aiming phase of elite archers

      Marsden, Lewis (University of Chester, 2015-09)
      The purpose of this study was to investigate the differences in the stability of alignment in elite archers when hold times in the aiming phase are increased. Eight elite archers (age = 21 ± 2.3 year, height = 1.79 ± .13m, mass = 78.35 ± 7.27kg) took part in the study (two females and six males). Participants shot six arrows under three separate conditions: 100%, 200% and 300% of average hold times in the aiming phase. The velocities of the key anatomical landmarks of alignment (LRSP, LLHE, LAP, RAP, RMHE, RRSP) were measured under all conditions and arrow score was recorded as a measure of performance. One-way repeated measures analysis of variance (ANOVA) and bonferroni post-hoc statistical analysis were adopted for kinematic variables. Friedman’s test of differences betweem repeated measures and Wilcoxen signed-rank test were adopted for arrow score. It was found that velocities at five of the six kinematic variables increased significantly as HT increased (LRSP: p < .001, LLHE: p = .022, LAP: p <.001, RMHE: p = .001, RRSP: p < .001). Arrow scores decreased significantly as HT increased (p = .02). It was concluded that increasing HTs during the aiming phase decreases the stability of alignment and subsequently reduces arrow score.
    • Stability regions of numerical methods for solving fractional differential equations

      Yan, Yubin; Nwajeri, Kizito U. (University of Chester, 2012-09)
      This dissertation deals with proper consideration of stability regions of well known numerical methods for solving fractional differential equations. It is based on the algorithm by Diethelm [15], predictor-corrector algorithm by Garrappa [31] and the convolution quadrature proposed by Lubich [3]. Initially, we considered the stability regions of numerical methods for solving ordinary differential equation using boundary locus method as a stepping stone of understanding the subject matter in Chapter 4. We extend the idea to the fractional differential equation in the following chapter and conclude that each stability regions of the numerical methods differs because of their differences in weights. They are illustrated by a number of graphs.
    • Stabilizing a nonlinear system by using feedback control

      Yan, Yubin; Kareem, Rasaq A. (University of Chester, 2010)
      This dissertation considers how to stabilize a nonlinear system by using feedback control. To stabilize a nonlinear system, we first need to find the unstable steady state. Then we consider the linearized problem at this steady state and solve the Riccati equation using the linear quadratic regulator (lqr). We then design the feedback controller on the linearized system,. Finally, we apply the feedback controller on the original nonlinear system. We use the forward Euler method, backward Euler method and Trapezoidal method to consider the discretization of the nonlinear system. We design the algorithm and consider two numerical examples of ecological models and verify that the results obtained are in accordance with theoretical results.
