description: The results of a Russian national study of the quality of preschool education (2016–2017, Nkindergartens = 1,301) are discussed with a focus on possible predictors of quality dynamics on the relations between Early Childhood Environment Rating Scale–Revised scores and group size, number of teachers in a group, child/adult ratio, teachers’ qualifications and working experience, and enrollment of teachers into in-service training. The child/adult ratio was found to be a stronger predictor of process quality than the group size and the number of teachers. No connection was revealed between process quality and teachers’ age and working experience. The impact of in-service training depends on the evidence- based orientation.

description: Frequency multiplication of terahertz signals on a solid state platform is highly sought-after for the next generation of high-speed electronics and the creation of frequency combs. Solutions to efficiently generate extreme harmonics (up to the $31^{\rm{st}}$ harmonic and beyond) of a terahertz signal with modest input intensities, however, remain elusive. Using fully nonperturbative simulations and complementary analytical theory, we show that 3D Dirac semimetals (DSMs) have enormous potential as compact sources of extreme terahertz harmonics, achieving energy conversion efficiencies beyond $10^{-5}$ at the $31^{\rm{st}}$ harmonic with input intensities on the order of $10$ MW/cm$^2$, over $10^5$ times lower than in conventional THz high harmonic generation systems. Our theory also reveals a fundamental feature in the nonlinear optics of 3D DSMs: a distinctive regime where higher-order optical nonlinearity vanishes, arising as a direct result of the extra dimensionality in 3D DSMs compared to 2D DSMs. Our findings should pave the way to the development of efficient platforms for high-frequency terahertz light sources and optoelectronics based on 3D DSMs.

title: Single-issue extra-parliamentary groups and liberal internationalism, 1899-1920
Creators: name: Dackombe, Barry Patrick
Publisher: name: The Open University
Year: 2008

description: This thesis provides an analysis of liberal internationalism at a critical point in its development, as manifested by the single-issue extra-parliamentary groups: the South Africa Conciliation Committee, the League of Liberals Against Aggression and Militarism, the Balkan Committee, the British Armenia Committee, the League of Nations Society and the League of Nations Union. They operated in a period of heightened international tension, beginning as it did with the capitalist inspired war in Southern Africa and culminating with the hopes for a new international order to supersede the 'international anarchy' of the pre-1914 years. They advocated an ethical foreign policy where the individual could play an important part in its advancement. Consequently, the 'scratch crowd' or 'stage army of the good' attracted to such groups serve as an important indicator of public attitudes to British foreign policy and international relations. Enthused with a belief in a world united in peace and co-operation they were primarily a combination of radical parliamentarians, journalists, academics and lawyers such as Lord Bryce, Noel Buxton, Aneurin Williams, J. A. Hobson, H. N. Brailsford, and Arnold Toynbee. In studying these groups collectively, the development of liberal internationalism from a post-Gladstonian moralist attitude derived from an evangelical religious sentiment, to an institutionalism of an entirely secular character becomes apparent, as does the centrality of the Eastern Question to their understanding of the international system and the policies they advocated for the rights of oppressed peoples to self-determination and the league of Nations. The effective use of insider/outsider strategies enabled the liberal internationalists to manage the interaction of British public opinion, international affairs and foreign policy at a significant juncture in the development of domestic and international politics.
The effect of low mass substructures on the Cusp lensing relation

Year: 2005

description: It has been argued that the flux anomalies detected in gravitationally lensed QSOs are evidence for substructures in the foreground lensing haloes. In this paper we investigate this issue in greater detail focusing on the Cusp relation which corresponds to images of a source located to the cusp of the inner caustic curve. We use numerical simulations combined with a Monte Carlo approach to study the effects of the expected power law distribution of substructures within LCDM haloes on the multiple images. Generally, the high number of anomalous flux ratios in the cusp configurations is unlikely explained by 'simple' perturbers (subhaloes) inside the lensing galaxy, either modeled by point masses or extended NFW subhaloes. We considered in our analysis a mass range of 10^5-10^7 Msun for the subhaloes. We also demonstrate that including the effects of the surrounding mass distribution, such as other galaxies close to the primary lens, does not change the results. We conclude that triple images of lensed QSOs do not show any direct evidence for dark dwarf galaxies such as cold dark matter substructure.

title: The Impact of the Leadership Programme for Serving Heads
Creators: name: Creissen, Terry
Publisher: name: The Open University
Year: 2008

description: This dissertation explores the impact of the Leadership Programme for Serving Heads (LPSH). It focuses on the process of the course and how this has influenced school leaders in the way that they run their schools. Firstly, the dissertation looks at the literature involved in leadership, training and measuring the impact of training on practice. Following this, there is an analysis of the methodology used and the research tools associated with a qualitative approach to study in this field. The data is then analysed against the theoretical perspectives of leadership. Finally, the findings from the case studies based in five English schools are analysed to try to identify any indications that changes and improvements in leadership have been as a result of attendance on the LPSH by the Headteachers of the case study schools. This dissertation looks at the assumptions set out within the programme by tracking through the key elements of leadership and training. Through this research, I have tried to discover the true impact of the LPSH in shaping and challenging experienced Heads in the leadership of their schools. I have looked at how some of the LPSH participants have adapted or maintained their leadership strategies and styles within their own institution. This has been achieved through two sets of interviews with the Headteachers and a range of teaching staff within their schools, matching their perceptions of the impact of the programme on them as leaders against the perceptions of their co-workers. From this, I have been able to draw some conclusions related to the views of the interviewees within these case study schools. The research demonstrates that the Headteachers involved did believe that the LPSH had a positive impact on their leadership, either through reflecting on their current approach and deciding that what they were doing was in line with best practice or by challenging their view and changing the way that they operated as a school leader. Similar perceptions were noted from their co-workers. The Headteacher participants of five case study schools gave feedback on how they thought that the LPSH had changed, and in many cases, improved their effectiveness as leaders in their schools. Similar feedback was demonstrated by teaching staff working within the case study schools, adding weight to the reliability of the findings. As with all small scale qualitative research, there are many limitations to the findings from the study. However, it is hoped that this research has identified some areas in leadership training and its impact in changing and improving leadership practice in schools that can then be taken further and investigated so that improvements in the quality of leadership training can be made for the benefit of school leaders.
Asymptotic Scaling of the Diffusion Coefficient of Fluctuating "Pulled" Fronts

description: We present a (heuristic) theoretical derivation for the scaling of the diffusion coefficient $D_f$ for fluctuating ``pulled'' fronts. In agreement with earlier numerical simulations, we find that as $N\to\infty$, $D_f$ approaches zero as $1/\ln^3N$, where $N$ is the average number of particles per correlation volume in the stable phase of the front. This behaviour of $D_f$ stems from the shape fluctuations at the very tip of the front, and is independent of the microscopic model.

description: Since the beginning of the 1970s, quality early childhood education and care (preschool) has been a national priority in Sweden. Over the years, policy changes such as the marketisation of the welfare system with increased state regulation and a focus on cost- effectiveness and performativity have resulted in modifications to the services offered. Because of its potential impact on children’s learning, wellbeing and development, the preschool environment—as reflected in its spatial design and pedagogical organisation— is considered an important quality indicator. Since the late 1990s and the beginning of the 2000s, there has been a tendency towards flexible organisation, with 40–50 young children and a team of 6–8 staff members working together and sharing educational spaces. Taking these reforms as the point of departure, this article examines the rationale for the policy changes and considers their implications for children, teachers and the quality of the preschool education. Data sources include policy documents as well as contemporary research. Findings indicate that policy reforms with shifting pedagogical organisation seem to be proposed and introduced without robust research evidence of the implications for children and teachers.
Fluid-like behavior of a one-dimensional granular gas

description: We study the properties of a one-dimensional (1D) granular gas consisting of $N$ hard rods on a line of length $L$ (with periodic boundary conditions). The particles collide inelastically and are fluidized by a heat bath at temperature $T_b$ and viscosity $γ$. The analysis is supported by molecular dynamics simulations. The average properties of the system are first discussed, focusing on the relations between granular temperature $T_g=m< v^2>$, kinetic pressure and density $ρ=N/L$. Thereafter, we consider the fluctuations around the average behavior obtaining a slightly non-Gaussian behavior of the velocity distributions and a spatially correlated velocity field; the density field displays clustering: this is reflected in the structure factor which has a peak in the $k \sim 0$ region suggesting an analogy between inelastic hard core interactions and an effective attractive potential. Finally, we study the transport properties, showing the typical sub-diffusive behavior of 1D stochastically driven systems, i.e. $ \sim Dt^{1/2}$ where $D$ for the inelastic fluid is larger than the elastic case. This is directly related to the peak of the structure factor at small wave-vectors.

title: Information-seeking on the Web with Trusted Social Networks - from Theory to Systems
Creators: name: Heath, Tom
Publisher: name: The Open University
Year: 2008

description: This research investigates how synergies between the Web and social networks can enhance the process of obtaining relevant and trustworthy information. A review of literature on personalised search, social search, recommender systems, social networks and trust propagation reveals limitations of existing technology in areas such as relevance, collaboration, task-adaptivity and trust. In response to these limitations I present a Web-based approach to information-seeking using social networks. This approach takes a source-centric perspective on the information-seeking process, aiming to identify trustworthy sources of relevant information from within the user's social network. An empirical study of source-selection decisions in information- and recommendation-seeking identified five factors that influence the choice of source, and its perceived trustworthiness. The priority given to each of these factors was found to vary according to the criticality and subjectivity of the task. A series of algorithms have been developed that operationalise three of these factors (expertise, experience, affinity) and generate from various data sources a number of trust metrics for use in social network-based information seeking. The most significant of these data sources is Revyu.com, a reviewing and rating Web site implemented as part of this research, that takes input from regular users and makes it available on the Semantic Web for easy re-use by the implemented algorithms. Output of the algorithms is used in Hoonoh.com, a Semantic Web-based system that has been developed to support users in identifying relevant and trustworthy information sources within their social networks. Evaluation of this system's ability to predict source selections showed more promising results for the experience factor than for expertise or affinity. This may be attributed to the greater demands these two factors place in terms of input data. Limitations of the work and opportunities for future research are discussed.
Persistence in Brownian motion of an ellipsoidal particle in two dimensions

description: We investigate the persistence probability $p(t)$ of the position of a Brownian particle with shape asymmetry in two dimensions. The persistence probability is defined as the probability that a stochastic variable has not changed it's sign in the given time interval. We explicitly consider two cases -- diffusion of a free particle and that of harmonically trapped particle. The later is particularly relevant in experiments which uses trapping and tracking techniques to measure the displacements. We provide analytical expressions of $p(t)$ for both the scenarios and show that in the absence of the shape asymmetry the results reduce to the case of an isotropic particle. The analytical expressions of $p(t)$ are further validated against numerical simulation of the underlying overdamped dynamics. We also illustrate that $p(t)$ can be a measure to determine the shape asymmetry of a colloid and the translational and rotational diffusivities can be estimated from the measured persistence probability. The advantage of this method is that it does not require the tracking of the orientation of the particle.

title: Young people's experiences of 'serious' romantic relationships in late adolescence: 'What is this thing called love?'
Creators: name: Forrest, Simon Peter
Publisher: name: The Open University
Year: 2008

description: This thesis mounts an in-depth exploration of young, white, Scottish people's views and experiences of falling in love with people of the opposite sex in the context of 'serious' romantic relationships formed in their late adolescence. It is located within the sociology of emotion and engages with debates about how emotional experience is shaped and influenced by social interaction, structures, cultural discourses and resources. The principal questions considered are: What array of social-cultural influences are pertinent to understanding these young people's experiences of love and 'serious' relationships? How and in what ways are these influences perceived to be inflecting or constitutive of these young people's experiences? In what ways do these young people's experiences exceed the account made possible through the sociology of emotion and, what possibilities and opportunities are there for elaborating this account? The study draws principally on data generated through interviews with young people studying for Highers in the sixth year of a secondary school. A grounded approach was used in analysis of these data. Findings include the development of taxonomies of 'serious' relationships which describe their constitutive elements, address the issue of why they are especially pertinent to young people in late adolescence and how this relates to their negotiation of specific social settings, interactions and developmental events. Gender, family and transition emerge as particular salient socio-cultural influences within these young people's accounts of their 'serious' relationships and the nature of each of these is explored in depth. I argue that the theoretical framework provided by the sociology of emotion has good explicative power in terms of identifying the array of social factors which are likely to be influencing emotional experiences but there is scope both for further research and to employ additional theoretical resources, especially psycho-dynamically inflected thinking, in order to explain emotional experience at the level of individual.

description: Very-high-energy (VHE) emission is usually interpreted in the synchrotron-self Compton (SSC) scenario, and expected from the low-redshift and high-luminosity gamma-ray bursts (GRBs), as GRB 180720B and GRB 190114C. Recently, VHE emission was detected by the H.E.S.S. telescopes from one of the closest burst GRB 190829A which was associated with the supernova (SN) 2019oyw. In this paper, we present a temporal and spectral analysis from optical bands to Fermi-LAT energy range over multiple observational periods beginning just after the BAT trigger time and extending for almost three months. We show that the X-ray and optical observations are consistent with synchrotron forward-shock emission evolving between the characteristic and cooling spectral breaks during the early and late afterglow in a uniform-density medium. Modeling the light curves together with its spectral energy distribution, it is shown that the outflow expands with an initial bulk Lorentz factor of $Γ\sim 30$, which is high for a low-luminosity GRBs and low for a high-luminosity GRBs. The values of the initial bulk Lorentz factor and the isotropic equivalent energy suggest that GRB 190829A is classified as an intermediate-luminosity burst and consequently, it becomes the first burst of this class in being detected in the VHE gamma-ray band by an imaging atmospheric Cherenkov telescope, and, in turn, the first event without being simultaneously observed by the Fermi-LAT instrument. Analyzing the intermediate-luminosity bursts with $z\lesssim 0.2$ such as GRB 130702A, we show that bursts with intermediate luminosity are potential candidates to be detected in very-high energies.

title: A cross-cultural analysis of apology strategies: Chinese and British
Creators: name: Xiang, Catherine Hua
Publisher: name: The Open University
Year: 2008

description: This study aims to explore cross-cultural differences in the ways that native British and Chinese people apologise. It attempts to further our understanding of deep sociocultural values underpinning such differences. The study is based on three sets of data (an open role-play, an evaluative questionnaire and an interview) and provides a comparative analysis of apology production and evaluation by native speakers of British English and Mandarin Chinese, as well as by language learner groups of these two target languages. Apologies are chosen because of their crucial importance in maintaining social relationships and face needs. The findings reveal different characteristics of Chinese and British apology, reflecting cross-cultural differences in social norms and value systems, as well as in perceiving face and social rights. The findings are interpreted within pragmatic and sociolinguistic theoretical frameworks, and are discussed in the following format: apology conceptualisation; apology realisation; individualism vs. collectivism; perception of face, politeness and rapport; perception of contextual variables. The performance of the two language learner groups is discussed in terms of pragmatic transfer, cross-cultural accommodation and potential causes of miscommunication. This study examines theoretical and pedagogical implications of cross-cultural differences in apology strategies, and so is useful for various groups who participate in intercultural communications between China and Britain, such as businessmen, linguists, language teachers and students.

description: Actin and non-muscle myosins have long been known to play important roles in growth cone steering and neurite outgrowth. More recently, novel functions for non-muscle myosin have been described in axons and dendritic spines. Consequently, possible roles of actomyosin contraction in organizing and maintaining structural properties of dendritic spines, the size and location of axon initial segment and axonal diameter are emerging research topics. In this review, we aim to summarize recent findings involving myosin localization and function in these compartments and to discuss possible roles for actomyosin in their function and the signaling pathways that control them.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

description: This paper uses time series data from 1972 to 2012 on Ghana to test the hypothesis that foreign aid can promote growth in developing countries. The ARDL approach to cointegration (bounds test) was employed to examine both the long run and short run relationships between aid and economic growth. The results of the bounds test showed that there is cointegration between foreign aid and economic growth in Ghana. This was further confirmed by the error correction term which was very significant and correctly signed. The error correction term showed that the speed of convergence to long run equilibrium is moderate. From the results, labour, capital and government expenditure have positive impact on economic growth in Ghana in both the long run and the short run whereas foreign aid and interest payment on external debt have negative impact on growth. In order to derive a positive benefit of foreign aid, we recommend the provision of economic aid which is geared towards capital formation and skills development of labour through education and training rather than political aid since the results show that capital and labour have positive impact on economic growth. We also recommend the provision of more grants and less loans as aid to Ghana because interest payment on external debt has been found in the study to have negative effect on economic growth because most foreign aid are not invested in projects with direct future cash flows.
AN OPTIMIZING UP-AND-DOWN DESIGN

description: Assume that the probability of success is unimodal as function of dose. Take the response to be binary and the possible treatment space to be a lattice. The Optimizing Up-and-Down Design allocates treatments to pairs of subjects in a way that causes the treatment distribution to cluster around the treatment with maximum success probability. This procedure is constructed to use accruing information to limit the number of patients that are exposed to doses with high probabilities of failure.The Optimizing Up-and-Down Design is motivated by Kiefer- Wolfowitz's stochastic approximation procedure. In this paper, we compare iLs performance to stochastic approximation. As an estimator of the best dose, simulation studies demonstrate that the mode of the empirical treatment distribution using the Optimizing Up-and-Down Design converges faster than does the usual estimator using stochastic approximation.
title: The UNESCO Genetics and Bioethics Declarations: Implications for Global Governance
Creators: name: Langlois, Adèle Fiona
Publisher: name: The Open University
Year: 2008

description: The sequencing of the entire human genome has opened up unprecedented possibilities for healthcare, but also ethical and social dilemmas about how these can be achieved, particularly in developing countries. This thesis examines two of the several international responses these dilemmas have spawned: the suite of declarations on genetics and bioethics adopted between 1997 and 2005 by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the Global Genomics Initiative proposed by the Toronto Joint Centre for Bioethics (TJCB). Through these initiatives, UNESCO and TJCB hope to promote the ethical governance of genetic and biomedical research, which is often conducted on an international basis. The thesis draws on interview, documentary and observational data, collected in Kenya and South Africa and from UNESCO, to assess the actual and potential efficacy of these two governance mechanisms, in terms of protecting individual research participants and reducing inequalities of health between North and South. It analyses the negotiation and subsequent implementation of the UNESCO declarations at international and national levels and the plans to date for the Global Genomics Initiative. Using as a conceptual framework particular branches of international relations theory concerned with global governance-namely regime theory, networked governance and cosmopolitan democracy-the thesis finds that determining where the balance of power between different actors should lie and, moreover, how this balance can be achieved is complex and difficult in international decision-making fora. Furthermore, the effective implementation of any regulations, policies or programmes there decided upon requires co-ordination among different sectors and organisations, across international and national levels. The thesis concludes that the UNESCO declarations on genetics and bioethics might provide a means to effect such a system of governance, if supported by networks of stakeholders both within and between states, perhaps through the proposed GGI.

description: The livestock sector in Tanzania has had and continues to have a major role for the overall national development. Historically, it has been an important arena for the debate over the appropriate development the country should undertake. Ideas of „tradition‟ and „modern‟ livestock production system(s) continue to influence policy making processes with the first, mobile pastoralism, considered backward by policy makers, and the second, the ranching system, being highly regarded in policies that touch on the development of the livestock sector as a whole. This paper uses the value chain approach as an analytical tool to provide a (re)assessment of the value of the pastoral system (from producers to end consumers) which is often absent from official statistics and figures besides the bare number of tax revenues. The analysis focuses specifically on red meat which has a crucial role for food security as well as in the culture of the country. The results of the paper show that the total value of the pastoral value chain with respect to meat only is substantially higher than the value of pastoralism reported in (scant) data in official statistics. These results strengthen the policy-related objective of the paper which is to prove the contribution of pastoralism as a highly efficient system that supports many livelihoods and worthy of more government support. The conclusion that can be drawn is that ranching system may well co-exists with pastoralism but the two need not be mutually exclusive.

description: The (inverse) beta-decay of uniformly accelerated protons (p -> n + e+ + ne) has been recently analyzed in the context of two-flavor neutrino mixing and oscillations. It has been shown that the decay rates as measured by an inertial and comoving observer are in agreement, provided that: i) the thermal nature of the accelerated vacuum (Unruh effect) is taken into account; ii) the asymptotic behavior of neutrinos is described through flavor (rather than mass) eigenstates; iii) the Unruh radiation is made up of oscillating neutrinos. Here we extend the above considerations to a more realistic scenario including three generations of Dirac neutrinos. By following the outlined recipe, we find that the equality between the two rates still holds true, confirming that mixing is perfectly consistent with the General Covariance of Quantum Field Theory. Notably, we prove that the analysis of CP violation in neutrino oscillations provides a further solid argument for flavor states as fundamental representation of asymptotic neutrino states. Our approach is finally discussed in comparison with the other treatments appeared in literature.

description: Assume that the probability of success is unimodal as function of dose. Take the response to be binary and the possible treatment space to be a lattice. The Optimizing Up-and-Down Design allocates treatments to pairs of subjects in a way that causes the treatment distribution to cluster around the treatment with maximum success probability. This procedure is constructed to use accruing information to limit the number of patients that are exposed to doses with high probabilities of failure.The Optimizing Up-and-Down Design is motivated by Kiefer- Wolfowitz's stochastic approximation procedure. In this paper, we compare iLs performance to stochastic approximation. As an estimator of the best dose, simulation studies demonstrate that the mode of the empirical treatment distribution using the Optimizing Up-and-Down Design converges faster than does the usual estimator using stochastic approximation.

description: We analyze the divergent part of the one-loop effective action for the noncommutative SU(2) gauge theory coupled to the fermions in the fundamental representation. We show that the divergencies in the 2-point and the 3-point functions in the $θ$-linear order can be renormalized, while the divergence in the 4-point fermionic function cannot.

title: The utility of molecular genetic analysis of museum specimens in studying deep-sea fish

description: The damaging effect of formalin on DNA and the inhibition of PCR are serious problems in molecular studies. The aims of the project were to investigate the possibility of using formalin-fixed, Steedman's preserved museum specimens in molecular investigations, especially organisms with unstudied genomes. A number of DNA extraction protocols and different pre-washing/drying regimes were tested. These gave different levels of success, but a guanidinium-based protocol developed in this study gave the best results. RAPD-PCR methodology was employed to test its applicability on preserved specimens, and it was used as a test of the efficiency of DNA extraction/amplifications and for developing species-specific PCR primers. Attempts to amplify mitochondrial DNA sequences with the six mitochondrial genes were mostly unsuccessful. Sporadic amplifications were obtained with primers of 16S and COIII genes.

This study provided the first molecular data on deep-sea fish (Nezumia aequalis and N. micronychodon) exclusively using formalin-fixed, Steedman's preserved museum specimens. Two genomic sequences of these fishes were determined and submitted to the GenBank database under accession numbers AY826774 - AY826792. Three specific primer sets (RAPD-derived) for Nezumia aequalis and N. micronychodon were designed to amplify PCR product sizes 300 bp - 350 bp. This study has demonstrated that an appropriate strategy and molecular approach could lead to the successful use of museum and other formalin-fixed archival collections even on organisms with unstudied genomes.

Supplementary evidence, related to the method of preservation, the usage of particular DNA extraction protocol and PCR marker system, was obtained from ten differently preserved mackerel (Scomber scombrus) specimens.

This study confirmed that the DNA extracted from preserved specimens possesses unique characteristics that make molecular investigations very difficult. Because of this, it is proposed that DNA extracted from preserved specimens should be referred to as "archival DNA (arDNA)".

description: In an effort to promote communication between the formal and phenomenological branches of the high-energy theory community, we provide a description of some important issues in supersymmetric and string phenomenology. We describe each within the context of string constructions, illustrating them with specific examples where applicable. Each topic culminates in a set of questions that we believe are amenable to direct consideration by string theorists, and whose answers we think could help connect string theory and phenomenology.

description: According to World Bank statistics, agricultural activities contribute about 33 per cent of the East African Community’s Gross Domestic Product, and up to 80 per cent of the populace depends on agriculture directly and indirectly for food, employment and income, while about 40 million people in EAC suffer from hunger. Intra-EAC trade is very low, that is, at 9 per cent of the total regional trade, but it is on upward trend. Agricultural trade accounts for over 40 per cent of the intra-EAC trade. This study investigated the effect of EAC regional trade agreement on the regions agricultural trade by analyzing the degree of trade creation and diversion effects. Several Augmented gravity models were estimated using the Pseudo Poisson Maximum Likelihood (PPML) Approach. Panel data from UNCOMTRADE, International Financial Statistics and World Development Indicators for the period 2000 – 2012 on the five EAC members and other 77 trade partners were used. The empirical findings showed mixed results for the different EAC member states. EAC regionalism had no significant effect on agricultural exports of Burundi, Rwanda and Uganda, while Kenya and Tanzania had reported significant effect of regionalism on their agricultural exports. This study concluded that EAC regional trade agreement has a potential of promoting EAC regional agricultural trade.
