title: An Exploration of Diverse Historical Influences on Leading and Managing Continuing Professional Development in Colleges in the Post-Incorporated English Further Education Sector
Creators: name: Cartwright, Marion
Publisher: name: The Open University
Year: 2020

description: This thesis explores the development of diverse historical influences on the leadership and management of continuing professional development (CPD), within post-incorporated general further education (FE) colleges in England. It has a central focus on the period of the first two decades after 1993 when colleges had left local authority control on incorporation. Underlying the research questions is a consideration of the educational, professional and business orientations of individual leaders, and the extent to which nuanced influences on CPD leadership co-exist, are balanced or in conflict, within the process of leaders mediating, translating and applying sector CPD policy in colleges. The combination of professional life history reflective data used with that of historical public documentary data aims to offer deeper insights into the range and relationship between the influences involved. The effect and differentiation of influences on CPD leadership and management approaches is considered within diverse college internal and external policy contexts of middle and senior managers, and at departmental and cross-college levels. Leaders’ and managers’ approaches to staff support and development are considered in the light of their own professional experiences, the ongoing changing requirements of external policy and resource boundaries as well as subject, skill and knowledge development and scope for individual staff professional enhancement. The scope of CPD leadership was taken to be as wide as that understood by the leaders and managers. The associated concepts of scope for leadership and management agency, internal organisational and internal and external accountabilities, and effects of staff identities in FE are evaluated. Whilst contributing to knowledge and understanding of this area, there is potential for collaborative sharing of leadership experience of the findings which could lead to more effective sharing of expertise, whilst enhancing organisational staff capacity and staffing strategies. There is potential for further research into leadership of CPD access particularly for the significant body of part-time staff in colleges.
Reconstructing The Commons : Temporary Living Infrastructure in Squamish, BC
Creators: name: Harper, Benham
Publisher: name: The University of British Columbia
Year: 2020

description: Reconstructing The Commons looks at the visibility of vehicle dwelling and the shrinking space available for “wild camping”. The project proposes creating a network of temporary living spaces empowering the remnant memories of communal use in the landscape. Using the town of Squamish as a test case, the recreational capital of Canada contends with a collision of many elements. Dealing with residents priced out of the community, a NIMBY mentality, and seasonal campers swell populations, the town has been forced to take steps to manage vehicle dwellers, whose numbers explode and overrun it in the summer months. A microcosm of a larger conversation surrounding property, and the right to belong, this thesis imagines a series of accommodations for the valley’s informal residents. Pushing for the evolution of the dispersed camps around the town, the project explores how investment into sites of informal occupation can transform problematic overused areas into a positive opportunity for inclusion into the community. Empowering our right to roam, the project seeks to balance the needs of different users in the local landscape.

description: We present 11 new open cluster candidates found in a systematic search for unknown star clusters using the astrometric and photometric data included in the Tycho2 catalog. The possible existence of these stellar aggregates is supported by the analysis of proper motions, color-magnitude diagrams, stellar density distributions, and by the visual inspection of the Digitized Sky Survey (DSS) plates. With these tools we were able to determine mean absolute proper motions as well as preliminary reddenings, distances and ages for the majority of the candidates. We found that most of them are possibly nearby (closer than about 600 pc) open clusters never studied before.

description: Human capital investment, especially in education, is a well-known precursor of economic growth in developing countries. In recent years, there has been a proliferation of microfinance programmes, yet evidence on whether microfinance leads to increased educational investment is tenuous at best. We utilise a large-scale cross-sectional household dataset from Bangladesh and geospatial data to study how microcredit participation and increasing microcredit incomes – that is, the extensive and intensive margins of microcredit – affects the probability of children’s school enrolment. The causal influence of microcredit participation on enrolments was estimated by utilising the propensity score matching (PSM) technique – a quasi-experimental treatment effects model. Whilst microcredit participation, the extensive margin, did not significantly influence the likelihood of school enrolment for boys, it increased girls’ enrolment. Further, microcredit income, the intensive margin, had a stronger influence on girls’ and younger siblings’ enrolment than on boys’ and older siblings’ enrolment. Omission of spatial influences can overstate microcredit influence on enrolment; while not utilising PSM can underestimate the influence of microcredit participation on enrolment. Results suggest policies that focus solely on increasing microcredit participation, without increasing the amount of microcredit incomes accessed by households, may be less effective at improving child education outcomes.

description: Studies from multiethnic populations are rarely reported but do indicate differences in phenotypic presentation and survival in amyotrophic lateral sclerosis (ALS). In this study, we aimed to investigate the natural history of a cohort of ALS patients from a multiethnic population. Methods: Data from ALS patients presenting to our multidisciplinary ALS clinic were prospectively collected from January 2015 to June 2020 as part of an ongoing hospital-based patient registry. Kaplan–Meier and Cox regression model were performed to identify potential prognostic factors. Results: A total of 144 ALS patients were recruited. We estimated the crude ALS incidence as 0.53 per 100,000 for 2019 but rises to 2 per 100,000 in patients aged 60–74 years. The majority of patients were of Chinese ethnicity (59.7%), followed by Malay (24.3%), Indian (11.1%), and others (4.9%). Malaysian Indians had a significantly steeper ALSFRS-R slope at diagnosis (p = 0.040). We found a worse prognosis in patients with bulbar-onset (HR = 1.915, p = 0.019), older age (HR = 1.052, p = 0.000), and who were fast-progressors (HR = 1.274, p = 0.000). In contrast, a higher body mass index (HR = 0.921, p = 0.007) and a longer time to diagnosis (HR = 0.967, p = 0.006), noninvasive ventilation (HR = 0.820, p = 0.000) and percutaneous endoscopic gastrostomy insertion (HR = 0.823, p = 0.000) were associated with better survival. On multivariate analysis, diagnostic delay and slow disease progression were associated with better survival. Conclusions: In our cohort, diagnostic delay and a slow disease progression were significantly associated with better survival in ALS. We also found ethnic variation with Chinese preponderance and more rapid disease progression in patients of Indian descent.

description: Apart from being the first attempt at investigating the impact of education-based homogamy and positive assortative mating on income inequality in a developing country context with very high levels of inequality and low education levels, this study pioneers in analysing the nonlinear relationship between mating patterns and income inequality. Further, the study contributes by the use of unconditional quantile regression and other distributional measures facilitated by the recentered influence function (RIF) method. The study finds convincing evidence of the existence of homogamy and positive assortative mating in South Africa. However, the strength of the relationship is seen to be weakening among younger cohorts as compared with older cohorts. The study further finds a non-linear U-shaped relationship between income inequality and the level of education-based homogamy, while a negative relationship is revealed between positive assortative mating and income inequality.

description: Some models of quantum gravity predict that the very structure of spacetime is `frothy' due to quantum fluctuations. Although the effect is expected to be tiny, if these spacetime fluctuations grow over a large distance, the initial state of a photon, such as its energy, is gradually washed out as the photon propagates. Thus, in these models, even the most monochromatic light source would gradually disperse in energy due to spacetime fluctuations over large distances. In this paper, we use science verification observations obtained with ESPRESSO at the Very Large Telescope to place a novel bound on the growth of spacetime fluctuations. To achieve this, we directly measure the width of a narrow Fe II absorption line produced by a quiescent gas cloud at redshift z=2.34, corresponding to a comoving distance of ~5.8 Gpc. Using a heuristic model where the energy fluctuations grow as sigma_E / E = (E/E_P)^alpha, where E_P = 1.22 x 10^28 eV is the Planck energy, we rule out models with alpha < 0.634, including models where the quantum fluctuations grow as a random walk process (alpha = 0.5). Finally, we present a new formalism where the uncertainty accrued at discrete spacetime steps is drawn from a continuous distribution. We conclude, if photons take discrete steps through spacetime and accumulate Planck-scale uncertainties at each step, then our ESPRESSO observations require that the step size must be at least >10^13.2 L_P, where L_P is the Planck length.

description: The electronic and transport properties of aluminum-graphene composite materials were investigated using ab initio plane wave density functional theory. The interfacial structure is reported for several configurations. In some cases, the face-centered aluminum (111) surface relaxes in a nearly ideal registry with graphene, resulting in a remarkably continuous interface structure. The Kubo-Greenwood formula and space-projected conductivity were employed to study electronic conduction in aluminum single- and double-layer graphene-aluminum composite models. The electronic density of states at the Fermi level is enhanced by the graphene for certain aluminum-graphene interfaces, thus, improving electronic conductivity. In double-layer graphene composites, conductivity varies non-monotonically with temperature, showing an increase between 300-400 K at short aluminum-graphene distances, unlike the consistent decrease in single-layer composites.

description: We reveal that the interplay between Rashba spin-orbit coupling and proximity-induced magnetization in a two-dimensional electron gas leads to peculiar transport properties and large anisotropy of magnetoresistance. While the related tunneling anisotropic magnetoresistance (TAMR) has been extensively studied before, we predict an effect with a different origin arising from the evolution of a resonant condition with the in-plane rotation of magnetization and having a much larger magnitude. The resonances in the tunneling emerge from a spin-parity-time symmetry of the scattering states. However, such a symmetry is generally absent from the system itself and only appears for certain parameter values. Without resonant behavior in the topological surface states of a proximitized three-dimensional topological insulator (TI), TAMR measurements can readily distinguish them from often misinterpreted trivial Rashba-like states inherent to many TIs.

description: We examine the Kuznets postulate that structural transformation leads to higher inequality using comparable panel data for a large number of developing and developed countries for 1960–2012. Countries are in different stages of structural transformation, being either structurally underdeveloped, structurally developing or structurally developed. In contrast to the Kuznets hypothesis, we find that the movement of workers to manufacturing unambiguously decreases income inequality, irrespective of the stage of structural transformation that a particular country is in. We also find that the movement of workers into services has a positive impact on inequality across our set of countries at an early stage of structural transformation and a negative effect at a later stage, suggesting that the Kuznets postulate may apply more for services-driven structural transformation than manufacturing- driven structural transformation. Overall, our findings confirm the positive development effects that structural transformation relating to manufacturing may have in developing countries, not merely through higher growth but by reducing inequality as well. However, for many low-income countries, where the realistic possibility of structural transformation may be the movement of workers from agriculture to services, our findings suggest that inequality may increase with further structural transformation.
title: The Garden as Political Form: From Archetype to Project
Creators: name: Marra, Olivia Neves
Publisher: name: The Open University
Year: 2020

description: Few architectures have ever been so widely adored and discussed as that of the garden. For it has served countless times as a significant paradigm of the human experience, for Eastern and Western cultures. Today most would say, it readily evokes an image of ‘innocence,’ somewhere for contemplation and ornamental cultivations. Despite many variations on the subject, in both literary and built forms, the term ‘garden’ has become ultimately challenging to define. Moreover, with the advent of a mainstream focus on ‘green space,’ architectural commissions of various scales will most likely deploy gardens as a means to improve environmental quality while providing a flashy image of ‘eco-friendliness.’ One may discover, however, that gardens have been historically critical to the domestication of the natural environment, as their various iterations defined distinct concepts of ownership, household, and urban territory. The thesis puts forward an alternative theory of the Western garden as an archetype of ideological enclosures, where the idea of limit becomes tangible and so gardening, a spatial praxis within yet ‘outside’ the city. In other words, the garden is an example of a shared space, with which given groups of people may construct and practice the way they want to live together in the world. Upon the guise of a PhD by Design, the thesis showcases an extensive production of authorial drawings to discuss these propositions through a genealogy of historical chapters, intermediated by design methodologies. The analyses of three singular events – the hortus conclusus (twelfth century), the suburban Roman villa (sixteenth century), and the English allotment (nineteenth century) – reveal how organisations, institutions, and subjects have transformed the garden archetype into different projects of ownership and household. As each chapter illuminates a key passage in the history of a specific urban territory – Tehran, Rome, and London – they are followed up by a ‘projective’ counterpart, reinterpreting their case studies to challenge the status quo of private property in the present contexts of those cities.

description: We study possible saturation effects in the total cross-section describing interaction of ultrahigh energy neutrinos with nucleons. This analysis is performed within the two approaches, i.e. within the Golec-Biernat Wüsthoff saturation model and within the scheme unifying the DGLAP and BFKL dynamics incorporating non-linear screening effects which follow from the Balitzki-Kovchegov equation. The structure functions in both approaches are constrained by HERA data. It is found that screening effects affect extrapolation of the neutrino-nucleon total cross-sections to ultrahigh neutrino energies $E_ν$ and reduce their magnitude by a factor equal to about 2 at $E_ν \sim 10^{12}GeV$. This reduction becomes amplified by nuclear shadowing in the case of the neutrino-nucleus cross-sections and approximate estimate of this effect is performed.

description: Exporting through global value chains (GVCs) has recently been highlighted as a panacea for weak industrialisation trends in the South. We study the long-run effects of GVC participation for a large set of countries between 1970 and 2008. We find strong evidence for the positive effects on productivity growth in the formal manufacturing sector. This effect is stronger when the gap with the global productivity frontier is larger. However, we find no evidence for a positive effect on employment generation. These findings also hold in analyses of sub-sets of countries and industries and are robust to the inclusion of non-manufacturing employment.

description: This paper provides further insight into the key concept of missing at random (MAR) in incomplete data analysis. Following the usual selection modelling approach we envisage two models with separable parameters: a model for the response of interest and a model for the missing data mechanism (MDM). If the response model is given by a complete density family, then frequentist inference from the likelihood function ignoring the MDM is valid if and only if the MDM is MAR. This necessary and sufficient condition also holds more generally for models for coarse data, such as censoring. Examples are given to show the necessity of the completeness of the underlying model for this equivalence to hold.
The significant effects of stellar mass estimation on galaxy pair fractions

description: There exist discrepancies in measurements of the number and evolution of galaxy pairs. The pair fraction appears to be sensitive to both the criteria used to select pair fraction and the methods used to analyze survey data. This paper explores the connection between stellar mass estimation and the pair fraction of galaxies making use of STEEL, the Statistical sEmi-Emprical modeL. Previous results have found the pair fraction is sensitive to choices made when selecting what qualifies as a pair, for example luminosity or stellar mass selections. We find that different estimations of stellar mass such as photometric choice mass-to-light ratio or IMF that effect the stellar mass function also significantly affect the derived galaxy pair fraction. By making use of the galaxy halo connection we investigate these systematic affects on the pair fraction. We constrain the galaxy halo connection using the stellar-mass-halo-mass relationship for two observed stellar mass functions, and the Illustris TNG stellar mass function. Furthermore, we also create a suite of toy models where the stellar-mass-halo-mass relationship is manually changed. For each stellar-mass-halo-mass relation the pair fraction, and its evolution, are generated. We find that enhancements to the number density of high mass galaxies cause steepening of the stellar-mass-halo mass relation, resulting in a reduction of the pair fraction. We argue this is a considerable cause of bias that must be accounted for when comparing pair fractions.

description: Recently, it has been pointed out that there exists a connection between the generalized parton distribution $E(x,0,t)$ and the Sivers asymmetry. For transversely polarized nucleon targets, generalized parton distributions are asymmetric in impact parameter space. This impact parameter space asymmetry, together with the final state interaction of the active quark, gives rise to the Sivers asymmetry in momentum space. We demonstrate this phenomenon explicitly in the scalar diquark model. This result also illustrates the physics that underlies the correlation between the anomalous magnetic moment and the Sivers asymmetry for a given quark flavor.

description: The rapid advancement of energy-efficient parallel ultra-low-power (ULP) ucontrollers units (MCUs) is enabling the development of autonomous nano-sized unmanned aerial vehicles (nano-UAVs). These sub-10cm drones represent the next generation of unobtrusive robotic helpers and ubiquitous smart sensors. However, nano-UAVs face significant power and payload constraints while requiring advanced computing capabilities akin to standard drones, including real-time Machine Learning (ML) performance and the safe co-existence of general-purpose and real-time OSs. Although some advanced parallel ULP MCUs offer the necessary ML computing capabilities within the prescribed power limits, they rely on small main memories (<1MB) and ucontroller-class CPUs with no virtualization or security features, and hence only support simple bare-metal runtimes. In this work, we present Shaheen, a 9mm2 200mW SoC implemented in 22nm FDX technology. Differently from state-of-the-art MCUs, Shaheen integrates a Linux-capable RV64 core, compliant with the v1.0 ratified Hypervisor extension and equipped with timing channel protection, along with a low-cost and low-power memory controller exposing up to 512MB of off-chip low-cost low-power HyperRAM directly to the CPU. At the same time, it integrates a fully programmable energy- and area-efficient multi-core cluster of RV32 cores optimized for general-purpose DSP as well as reduced- and mixed-precision ML. To the best of the authors' knowledge, it is the first silicon prototype of a ULP SoC coupling the RV64 and RV32 cores in a heterogeneous host+accelerator architecture fully based on the RISC-V ISA. We demonstrate the capabilities of the proposed SoC on a wide range of benchmarks relevant to nano-UAV applications. The cluster can deliver up to 90GOp/s and up to 1.8TOp/s/W on 2-bit integer kernels and up to 7.9GFLOp/s and up to 150GFLOp/s/W on 16-bit FP kernels.

description: This paper studies the impact of unmanned aerial vehicle (UAV) wobbling on the coherence time of the wireless channel between UAVs and a ground user equipment (UE), using a Rician multi-path channel model. We consider two different scenarios for the number of UAVs: (i) single UAV scenario (SUS), and (ii) multiple UAV scenario (MUS). For each scenario, we model UAV wobbling by two random processes, i.e., the Wiener and sinusoidal processes, and characterize the channel autocorrelation function (ACF) which is then used to derive the coherence time of the channel. For the MUS, we further show that the UAV-UE channels for different UAVs are uncorrelated from each other. A key observation in this paper is that even for small UAV wobbling, the coherence time of the channel may degrade quickly, which may make it difficult to track the channel and establish a reliable communication link.

description: Small-world and scale-free networks are known to be more easily synchronized than regular lattices, which is usually attributed to the smaller network distance between oscillators. Surprisingly, we find that networks with a homogeneous distribution of connectivity are more synchronizable than heterogeneous ones, even though the average network distance is larger. We present numerical computations and analytical estimates on synchronizability of the network in terms of its heterogeneity parameters. Our results suggest that some degree of homogeneity is expected in naturally evolved structures, such as neural networks, where synchronizability is desirable.

description: This thesis examines the reception of Roman slavery in recent ancient world television drama through one primary text, Starz’s Spartacus (2010-13) and what it reveals about the way we conceptualise ancient slavery in this under-researched medium. Applying a key tenet of reception theory, namely that fictional works set in the past potentially yield insight into the concerns of the present, it explores how the series’ representation of slavery reflects contemporary issues around gender, sexuality, race, identity, status and power. My comparative methodology comprises an in-depth character and thematic analysis of the series and other recent onscreen slave narratives. It shows that the series is subject to a range of influences, from modern popular culture to aspects of the classical sources. However, commercial imperatives still drive the selection and appropriation of material. This explains the ubiquity of certain tropes generic to the cable industry, namely graphic sexual content and violence, and enslaved women in particular are portrayed almost exclusively through the lens of sexual slavery. Since the series is about a slave rebellion, it privileges the most brutal aspects of slavery and portrays the institution as inherently dehumanising, violent and disempowering. This study also shows that the series can be situated within a wider tradition of representing slavery onscreen, while the moral ambivalence of servile characters, behaviour and attitudes not only reflects more complex modern TV narratives, but also indicates a desire to differentiate the series culturally and politically from the legacy of the famous 1960 film. Finally, by using slavery to explore themes such as the abuse of power, the importance of liberty and resistance, and the implications of denying bodily and sexual agency and rights, it encourages audiences to reflect upon injustices in their own societies.

description: Landscape Architecture has reacted to the pigeon-holing of its scope centered on contained parks and gardens, by expanding into other domains such as landscape urbanism, green infrastructure, and large scale climate adaptation. While these efforts are extremely important, this project takes a different position as it returns to the garden, and a globally significant flower species; the rose. PDA (Public Display of Affection) is a project that takes place at the University of British Columbia Rose Garden. As a typological case study, it co-opts the monofunctional and monocultural condition of the rose garden as an experimentation ground for the University’s Public Art Strategy. Framed conceptually by theory surrounding Affective Ecology, and guided by Donna Haraway’s writings in Staying with the trouble: making kin in the Chthulucene, this project is an interpretive exercise that seeks to arouse the existing condition of the garden through embedding and extending invitations within the site to renegotiate terms of behaviour, and expand the potentialities of experience and encounter between human and non-human organisms.

description: Trends in free trade in TPP, RCEP, and bilateral FTA suggest that it is unrealistic to think that high tariffs will remain on agricultural products in perpetuity. The standard economic method of trial calculation of FTA effects is the use of applied generable equilibrium analysis through the use of the GTAP model. However, the elasticity of substitution among import products set in GTAP adopts the so-called "Rule of Two," whereby values are double those for domestic products and import products; the econometric evidence is, therefore, unclear. In simulations of tariff elimination through the GTAP model and other schema, the elasticity of substitution value plays an important role, so it must be accurately measured. One major issue surrounding the calculation of elasticity of substitution is simultaneity. Theoretical research into the above begins with Leamer (1981), with Feenstra (1994) using the features of panel data to derive an empirical methodology, and later research by Soderbery (2015) describes a methodology utilizing Limited Information Maximum Likelihood (LIML) and constrained LIML. In this paper, we focus on the Japanese dairy products market as an example of a market in which high tariffs persist. By utilizing Soderbery’s (2015) methodology, (1) we estimate the elasticity of substitution of dairy products among Japanese imports and conduct a simulation of free trade comparing the elasticity of substitution defined respectively in the GTAP model and in the parameters estimated in our research, (2) with the respective results compared to consider the difference between divergent elasticity of substitution. The results show that the estimates of elasticity of import substitution for dairy products in Japan yield a lower value than those set in GTAP, and our findings quantitatively suggest that, as a result of the above, FTA simulations produced a smaller impact in terms of trade diversion effects.

description: We interviewed 201 shrimp farmers in a district in Ca Mau province in southern Vietnam in 2015 and collected shrimp samples from each household’s pond for the screening of residual drugs. The test revealed residual veterinary drugs exceeding the acceptable limit by the Japan standard were found in 40 farmers’ shrimps. We conducted Probit and Tobit regressions using cross-sectional data to examine whether results of the residue tests correlate significantly with some of the farmers’ characteristics and farm management practices. This study finds that 1) receiving BMPs training and keeping the record of shrimp seed have significant and positive effects on reducing veterinary drugs use, 2) a closer relationship between farmers and extension officers have significant and positive effects on reducing antibiotics use, 3) almost all the farmers do not know the exact names of prohibited elements and which inputs actually contain these elements.

description: Giant Gilbert damping anisotropy is identified as a signature of strong Rashba spin-orbit coupling in a two-dimensional antiferromagnet on a honeycomb lattice. The phenomenon originates in spin-orbit induced splitting of conduction electron subbands that strongly suppresses certain spin-flip processes. As a result, the spin-orbit interaction is shown to support an undamped non-equilibrium dynamical mode that corresponds to an ultrafast in-plane Néel vector precession and a constant perpendicular-to-the-plane magnetization. The phenomenon is illustrated on the basis of a two dimensional $s$-$d$ like model. Spin-orbit torques and conductivity are also computed microscopically for this model. Unlike Gilbert damping these quantities are shown to reveal only a weak anisotropy that is limited to the semiconductor regime corresponding to the Fermi energy staying in a close vicinity of antiferromagnetic gap.

description: Supermarkets have already been in China for more than 20 years. Though boasting many advantages, they have not replaced wet markets to become major retail sites for fresh food. Both of them co-exist while competing today. Based on the perspective of differences between quality and price, this paper investigates supermarkets and wet markets in Nanjing, and uses Hedonic models to analyze the competitive relationships between supermarkets and wet markets on managing fresh vegetables. The main conclusions are as follows: (1) Supermarkets holds quality as its advantage, while wet markets prevail with low price. (2) Differences in quality can partly explain price differences, prices in wet markets fluctuate more widely over time. (3) In terms of the sale of fresh vegetables, supermarkets do not compete directly with wet markets, but highly concentrate on the high quality and high price of its goods. (4) After controlling quality differences, some vegetables’ prices in supermarkets are still significantly higher than those in wet markets. It shows that except quality differences, supermarkets have other differentiating advantages, such as variety, convenience, environment and characteristic service, etc.

description: This paper is based on planned behavior theory to analyze how members act when they participate in cooperative governance. A Bviariate Probit Model is applied to investigate the determinants of apple growers’ participation in cooperative governance which include the behavioral characteristics of members to participate in cooperative, cooperative characteristic, revenue change of member before and after join in cooperative, trust and commitment in between member and cooperative, growers own as well as their household characteristics. Data from a field survey in Shandong, Henan, Shaanxi and Gansu of 25 cooperatives and 273 Apple planting households (all households are cooperative members) are used to estimate the model. Empirical results show that after members joining cooperative, their revenue improved, the contractual relationship is established and they can get better services from cooperatives, all of these can improve the degree of members’ participation in cooperative governance. Finally, the corresponding countermeasures and suggestions are proposed from the perspective of standardizing cooperative governance.
