The sources of inequity in the education system of Serbia and how to combat them

The concept of equal opportunity for all students is deeply embedded in the Serbian constitution and in education laws. On that level, there is no doubt that everyone is ensured an opportunity to receive quality education. Many measures in education policy have been created specifically to achieve this objective and make the system fair and inclusive. The Coleman Report was linked to a wave of optimism that certain educational measures would help in achieving these noble goals. This aim is a high priority in education in a democratic country, and due to its importance needs to be re-examined. Thus, the present research examines the equity of students in the Serbian education system, detecting areas on all educational levels that could be (or already are) systemic sources of inequity (e.g., criteria for preschool institution enrolment, the system of student awards, rationalisation of the school network, the concept of entrance exams to secondary school or university, etc.). A number of measures have already been taken in the system specifically to deal with inequity (e.g., the Preschool Preparatory Programme, dropout measures, inclusion, scholarships, etc.). The effects of these measures in particular are analysed in the present work. In addition to an analysis of the systemic sources of inequity in the Serbian education system, the article also makes recommendations for their overcoming. (DIPF/Orig.)

Guardian dogs protect sheep by guarding sheep, not by establishing territories and excluding predators

Guardian animals have been a common non-lethal method for reducing predator impacts on livestock for centuries in Europe. But elsewhere, livestock producers sometimes doubt whether such methods work or are compatible with modern livestock husbandry practices in extensive grazing systems. In this study we evaluate the hypothesis that guardian dogs primarily ‘work’ by establishing and defending territories from which canid predators are excluded. Eight maremmas and six free-ranging wild dogs of different sexes were fitted with GPS collars and monitored for 7 months on a large sheep property in north Queensland, Australia. Wild dog incursions into the territories of adjacent wild dogs and maremmas were recorded. Wild dog territories never overlapped and their home ranges infrequently overlapped. In contrast, 713 hourly locations from 120 wild dog incursions into maremma territories were recorded, mostly from three wild dogs. These three wild dogs spent a mean of 2.5–5.9 h inside maremma territories during incursions. At this location, maremmas worked by guarding sheep and prohibiting fine-scale interaction between wild dogs and sheep, not by establishing a territory respected by wild dogs. We conclude that shepherding behaviour and boisterous vocalisations of guardian dogs combined with the flocking behaviour of sheep circumvents attacks on sheep but does not prevent nor discourage wild dogs from foraging in close proximity. Certain husbandry practices and the behaviour of sheep at parturition may incur greater predation risk.

Effect of Experience on Alibi Generation and Expectation

Members of the general population have high expectations of people who are asked to corroborate an alibi for the suspect of a crime. The general belief is that it is easy to provide an alibi if a person is innocent, and therefore guilt should be assumed when an alibi cannot be provided. The possibility that having to generate an alibi oneself could influence expectations was examined. Additionally, potential changes in opinion after being provided with positive or negative feedback were explored. Results showed a significant difference in expectations based on whether participants were correct or incorrect in identifying the suspect, that is, whether participants were able to provide an alibi. Those who were incorrect had lower expectations of themselves and of others than those who were correct. Making jurors aware of the difficulty in providing an alibi may lead to fairer treatment of suspects who have difficulty providing one.

Transmission Easement and Adverse Possession of Transmission Easement in the Polish Law

The object of analysis in the text are the issues concerned with the transmission easement and the adverse possession thereof on the grounds of the Polish law. The text features: (1) a historical outline of the solutions concerned with easements in the Polish law following 1945, (2) the institution of transmission easement introduced in 2008 and the solutions concerned with the claims for the establishment thereof at court, (3) the institution of adverse possession of transmission easement pursuant to civil law regulations, judicature and the legal doctrine. On account of the need to elaborate the wide-ranging legal issues concerned with the transmission easement in this text, the analysis embraces two research questions giving rise to the following conclusions: (1) What function is performed by the institution of transmission easement in the system of civil-law relations in the Polish law? The legislator in the articles introducing a transmission easement ossified the solutions functioning in the judicature of the Polish courts before 2008. The legal interpretation took a turn for clarification, that is for the establishment of a norm in the situation where its comprehension was dubious. It is noteworthy that in the period prior to 2008, the law provided for easement appurtenant, and on account of the usual course of judicial decisions also for easement appurtenant with the content corresponding to transmission easement. In 2008 these two “legal existences” were supplemented with a transmission easement, which nevertheless failed to resolve all the legal problems; nay, this gave rise to even more problems, e.g. the one of non-establishment of interpolar norms which would address the issues arising in connection with the use of various easement institutions in legal transactions. While amending the civil law, the legislator aimed to bring order to legal transactions by streamlining the unregulated actual state of easement in relation to transmission infrastructure, but also in relation to the situations where an easement was yet to be established and a facility yet to be constructed. Thus, such action is intended to regulate the disorderly legislation in force as well as to safeguard investment processes. This is of particular significance, for example, for energy companies which are burdened with statutory public-law obligations as regards securing energy supplies and providing for the development of energy infrastructure. Hence, the de facto introduced civil-law solutions indirectly served to realise the principles of the doctrine of easement in the public interest. (2) What legal problems in the civil-law relations does the application of the institution of transmission easement by adverse possession entail? On account of the functioning of various institutions of easement, that is (1) an easement appurtenant, (2) an easement appurtenant with the content corresponding to a transmission easement, and as of 2008 (3) a transmission easement, a problem arose as to which of the given easements companies exercised in particular periods, all the more so because before 1989 the State Treasury owned them and many of the transmission facilities were put in place by virtue of administrative decisions. The commonly held belief is that in the period of “society-oriented economy” as well as up to 2008 infrastructure companies could exercise an easement appurtenant which corresponded to the content of a transmission easement. Therefore, in such a case the running of the prescriptive period should allow for the general rules laid down for an easement appurtenant. Apart from the problem of the relation of a capacity to exercise a right to property and the free development of civil-law relations before 1989, the recognition of the running of prescriptive periods – given the functioning of the three various easements as legal institutions – became a significant legal problem. By way of illustration, the recognition – against the period of exercising transmission easement – of the period required for the acquisition thereof by adverse possession, whereby before 3 August 2008 the real estate featured the legal state corresponding to the content of this right, is debatable. One cannot recognise that within that period a transmission easement was exercised, because such a right was not in existence as yet. Therefore, the institution that might be employed is the running of the period as regards the adverse possession in relation to an easement appurtenant with the content of a transmission easement. Still, the problem remains as to whether the period of the exercise of the easement appurtenant with the content corresponding to a transmission easement can be recognised against the period of possession required for the adverse possession of a transmission easement pursuant to the regulations introduced in 2008. One might incline to the position whereby in such a case it would be right to fully recognise – against the period of exercising a transmission easement – the period of exercising an easement appurtenant corresponding thereto in respect of its content. That being so, the adverse possession of a transmission easement might ensue in such a situation on 3 August 2008 at the earliest, that is the moment the regulations governing this right come into effect. Conversely, if the prescriptive period expires before that date, the entrepreneur would acquire an easement appurtenant with the content corresponding to the transmission easement. Such an interpretation is aligned with the purpose intended by the legislator, which is to bring order to the actual state of the broadest scope with the aid of a new legal instrument. The text, while analysing the issue of a transmission easement and an adverse possession thereof as a institution of the civil law, presents only some selected problems. Hence, the analysis does not include, for example, the issues concerned with claims for remuneration (for usufruct without contractual basis or usufruct fees), or claims for compensation (redress or amends). Furthermore, the text does not conduct a more profound analysis of the relation between the provisions regulating public-law relations (e.g. acts of law introducing the institution of dispossession) and the provisions regulating civil-law relations (the easements in question).

The Scottish Parliament in the 15th and 16th centuries

Earlier histories of the Scottish parliament have been somewhat constitutional in emphasis and have been exceedingly critical of what was understood to be parliament's subservience to the crown. Estimates by constitutional historians of the extreme weakness of parliament rested on an assessment of the constitutional system. The argument was that many of its features were not consistent with a reasonably strong parliament. Because the 'constitution' is apparently fragmented, with active roles played by bodies such as the lords of articles, the general council and the convention of estates, each apparently suggesting that parliament was inadequate, historians have sometimes failed to appreciate the positive role played by the estates in the conduct of national affairs. The thesis begins with a discussion of the reliability of the printed text of APS and proceeds to an examination of selected aspects of the work of parliament in a period from c 1424-c 1625. The belief of constitutional historians such as Rait that conditions In Scotland proved unfavourable to the interests and. effectiveness of parliament in the fifteenth and sixteenth centuries, is also examined. Chapter 1 concludes that APS is a less than reliable text, particularly for the reign of James I. Numerous statutes were excluded from the printed text and they are offered below for the first time. These statutes have been a useful addition to our understanding of the reign of James I. Chapter 2 analyses the motives behind the schemes for shire representation and concludes that neither constitutional theory nor political opportunism explains the support which James I and James VI gave to these measures. Both these monarchs were motivated by the realisation that their particular ambitions were dependent on winning the support of the estates whose ranks should include representatives from the shires. Chapter 3 examines the method of electing the lords of articles, the composition of this committee, and some aspects of its operation. The conclusion is that in the main the estates were the deciding force in the choice of the lords of articles. The committee's composition was more a reflection of a desire for a balance between representatives from north and south of the Forth and for the most important burghs and clergy to be selected than an attempt at electing government favourites. The articles did exercise a significant control over the items which came before parliament but this control was not absolute and applied to government as well as private legislation. Chapter 4 questions the traditional view that the general council and convention of estates were the same body. It is argued that they were two different institutions with different powers, but that they nevertheless worked within certain limits and were careful not to usurp the authority of parliament. Chapter 5 concedes that taxation was sometimes decided outside parliament; that the irregularity of taxation certainly weakened the bargaining power of the estates and that the latter did not appear to capitalise on these occasions when taxation was an issue. But the tendency was to ensure that, whether in or out of parliament, the decision to impose taxation was taken by a large number of each estate. The infrequency of taxation was a direct consequence of an unwillingness among the estates to agree to a regular taxation and their preference to ensure for the crown an alternative source of income. Moreover taxation was one issue, which more than any other, would be subject to contentious opposition by the estates, and could lead to the crown's defeat. Chapter 6 is concerned with ecclesiastical representation after the Reformation and the church's attitudes to the possibility of ministerial representation. Some ministers had doctrinal misgivings but the majority came to believe that the church's absence from parliament bad severely reduced. the influence of the church. That no agreement was forthcoming on a system of ministerial representation, particularly after 1597, is attributable to the estates' unwillingness to compromise and, not to the strength of opposition in the church. Chapter 7 examines the institutions which are sometime seen as 'rivals' of parliament and concludes that institutions such as the privy council were generally very careful in matters which needed the approval of parliament, and seemed aware of the greater authority of parliament. Chapter 8 which illustrates how parliament had the right to be consulted in all important matters of state, brings together the main points of the earlier chapters and offers further illustrations of the essential role which parliament played in the conduct of national affairs. Whether or not the system can be regarded as constitutionally sound, the estates in Scotland could observe parliament's day-to-day operation with some satisfaction. All in all, there is little convincing evidence that parliament was as weak as some historians would have us believe.

Multi-Agent Simulation and Management Practices

Intelligent agents offer a new and exciting way of understanding the world of work. Agent-Based Simulation (ABS), one way of using intelligent agents, carries great potential for progressing our understanding of management practices and how they link to retail performance. We have developed simulation models based on research by a multi-disciplinary team of economists, work psychologists and computer scientists. We will discuss our experiences of implementing these concepts working with a well-known retail department store. There is no doubt that management practices are linked to the performance of an organisation (Reynolds et al., 2005; Wall & Wood, 2005). Best practices have been developed, but when it comes down to the actual application of these guidelines considerable ambiguity remains regarding their effectiveness within particular contexts (Siebers et al., forthcoming a). Most Operational Research (OR) methods can only be used as analysis tools once management practices have been implemented. Often they are not very useful for giving answers to speculative ‘what-if’ questions, particularly when one is interested in the development of the system over time rather than just the state of the system at a certain point in time. Simulation can be used to analyse the operation of dynamic and stochastic systems. ABS is particularly useful when complex interactions between system entities exist, such as autonomous decision making or negotiation. In an ABS model the researcher explicitly describes the decision process of simulated actors at the micro level. Structures emerge at the macro level as a result of the actions of the agents and their interactions with other agents and the environment. We will show how ABS experiments can deal with testing and optimising management practices such as training, empowerment or teamwork. Hence, questions such as “will staff setting their own break times improve performance?” can be investigated.

Closing Pandora's box: a defence of Alvin Plantinga's epistemology of religious belief

I argue (1) that Alvin Plantinga’s theory of warrant is plausible and (2) that, contrary to the Pandora’s Box objection, there are certain serious world religions that cannot successfully use Plantinga’s epistemology to demonstrate that their beliefs could be warranted in the same way that Christian belief can be warranted. In arguing for (1), I deploy Ernest Sosa’s Swampman case to show that Plantinga’s proper function condition is a necessary condition for warrant. I then engage three objections to Plantinga’s theory of warrant, each of which attempts to demonstrate that his conditions for warrant are neither necessary nor sufficient. Having defended the plausibility of Plantinga’s theory of warrant, I present and expand his key arguments to the effect that naturalism cannot make use of it. These arguments provide the conceptual tools that are needed to argue for (2): that there are certain world religions that cannot legitimately use Plantinga’s theory of warrant to demonstrate that their beliefs could be warranted in the same way that Christian belief can be warranted.

The Return of Institutions. On the Latest Change in the Research on Social and Economic Development

The paper describes the latest change in the research on social and economic development of states. This change is characterized mainly by a strong emphasis put on the role of institutions as key instruments of reducing the development gap between countries. It is argued that in the years after 1989 institutions have disappeared from mainstream academia and major intellectual debates because of: (1) the widespread belief in global convergence of capitalism and (2) the modernization theory which prevailed in the social science in the 1990s. The article indicates that institutions were once again brought into focus as a result of (1) a wider debate about the institutional sources of growth and development sparked by Acemoglu and Robinson’s Why Nations Fail, (2) the beginning of the global economic crisis of 2008 triggered by the fall of American investment bank Lehman Brothers (3) diversified consequences of the economic crisis seen all over Europe and the USA which illustrate (4) the institutional varieties of capitalism.

THE EFFECT OF SCHOOL CLIMATE (STUDENT AND TEACHER ENGAGEMENT) ON STUDENT PERFORMANCE

Title of Dissertation: THE EFFECT OF SCHOOL CLIMATE (STUDENT AND TEACHER ENGAGEMENT) ON STUDENT PERFORMANCE Kenneth L. Marcus, Doctor of Education, 2016 Directed By: Dr. Thomas Davis, Assistant Professor, Education Policy and Leadership, Department of Teaching and Learning, Policy and Leadership This quantitative research study was designed to compute correlations/relationships of student engagement and student achievement of fifth grade students. Secondary information was collected on the relationship of FARMS, type of school, hope, and well-being on student achievement. School leaders are charged with ensuring that students achieve academically and demonstrate their ability by meeting identified targets on state and district mandated assessments. Due to increased pressure to meet targets, principals implement academic interventions to improve student learning and overlook the benefits of a positive school climate. This study has provided information on the impact of school climate on student achievement. To conduct this study, the researcher collected two sets of public fifth grade data (Gallup Survey student engagement scores and DSA reading, mathematics, and science scores) to determine the relationship of student performance and school climate. Secondary data were also collected on teacher engagement and the percentage of students receiving FARMS to determine the effect on students. The findings from this study reinforced the belief that school climate can have a positive effect on student achievement. This study contributed quantitative data about the relationship between school climate and school achievement.

Error analyses reveal contrasting deficits in “theory of mind”: neuropsychological evidence from a 3-option false belief task

Perspective taking is a crucial ability that guides our social interactions. In this study, we show how the specific patterns of errors of brain-damaged patients in perspective taking tasks can help us further understand the factors contributing to perspective taking abilities. Previous work (e.g., Samson, Apperly, Chiavarino, & Humphreys, 2004; Samson, Apperly, Kathirgamanathan, & Humphreys, 2005) distinguished two components of perspective taking: the ability to inhibit our own perspective and the ability to infer someone else’s perspective. We assessed these components using a new nonverbal false belief task which provided different response options to detect three types of response strategies that participants might be using: a complete and spared belief reasoning strategy, a reality-based response selection strategy in which participants respond from their own perspective, and a simplified mentalising strategy in which participants avoid responding from their own perspective but rely on inaccurate cues to infer the other person’s belief. One patient, with a self-perspective inhibition deficit, almost always used the reality-based response strategy; in contrast, the other patient, with a deficit in taking other perspectives, tended to use the simplified mentalising strategy without necessarily transposing her own perspective. We discuss the extent to which the pattern of performance of both patients could relate to their executive function deficit and how it can inform us on the cognitive and neural components involved in belief reasoning.

States' Responding Behavior in Conflict: Asymmetric Response and Strategic Conflict Avoidance

State responses to external threats and aggression are studied with focus on two different rationales: (1) to make credible deterrent threats to avoid being exploited, and (2) to minimize the risk of escalation to unwanted war. Given external aggression, the target state's responding behavior has three possibilities: concession (under-response), reciprocation, and escalation. This study focuses on the first two possibilities and investigates how the strategic nature of crisis interaction can explain the intentional choice of concession or avoidance of retaliation. I build a two-level bargaining model that accounts for the domestic bargaining situation between the leader and the challenger for each state. The model's equilibrium shows that the responding behavior is determined not only by inter-state level variables (e.g. balance of power between two states, or cost of war that each state is supposed to pay), but also the domestic variables of both states. Next, the strategic interaction is rationally explained by the model: as the responding state believes that the initiating state has strong domestic challenges and, hence, the aggression is believed to be initiated for domestic political purposes (a rally-around-the-flag effect), the response tends to decrease. The concession is also predicted if the target state leader has strong bargaining power against her domestic challengers \emph{and} she believes that the initiating leader suffers from weak domestic standing. To test the model's prediction, I conduct a lab experiment and case studies. The experimental result shows that under an incentivized bargaining situation, individual actors are observed to react to hostile action as the model predicts: if the opponent is believed to suffer from internally driven difficulties, the subject will not punish hostile behavior of the other player as severely as she would without such a belief. The experiment also provides supporting evidence for the choice of concession: when the player finds herself in a favorable situation while the other has disadvantages, the player is more likely to make concessions in the controlled dictator game. Two cases are examined to discuss how the model can explain the choice of either reciprocation or concession. From personal interviews and fieldwork in South Korea, I find that South Korea's reciprocating behavior during the 2010 Yeonpyeong Island incident is explained by a combination of `low domestic power of initiating leader (Kim Jong-il)' and `low domestic power of responding leader (Lee Myung-bak).' On the other hand, the case of EC-121 is understood as a non-response or concession outcome. Declassified documents show that Nixon and his key advisors interpreted the attack as a result of North Korea's domestic political instabilities (low domestic power of initiating leader) and that Nixon did not have difficulties at domestic politics during the first few months of his presidency (high domestic power of responding leader).

Essays on Uncertainty, Imperfect Information, and Investment Dynamics

Understanding how imperfect information affects firms' investment decision helps answer important questions in economics, such as how we may better measure economic uncertainty; how firms' forecasts would affect their decision-making when their beliefs are not backed by economic fundamentals; and how important are the business cycle impacts of changes in firms' productivity uncertainty in an environment of incomplete information. This dissertation provides a synthetic answer to all these questions, both empirically and theoretically. The first chapter, provides empirical evidence to demonstrate that survey-based forecast dispersion identifies a distinctive type of second moment shocks different from the canonical volatility shocks to productivity, i.e. uncertainty shocks. Such forecast disagreement disturbances can affect the distribution of firm-level beliefs regardless of whether or not belief changes are backed by changes in economic fundamentals. At the aggregate level, innovations that increase the dispersion of firms' forecasts lead to persistent declines in aggregate investment and output, which are followed by a slow recovery. On the contrary, the larger dispersion of future firm-specific productivity innovations, the standard way to measure economic uncertainty, delivers the ``wait and see" effect, such that aggregate investment experiences a sharp decline, followed by a quick rebound, and then overshoots. At the firm level, data uncovers that more productive firms increase investments given rises in productivity dispersion for the future, whereas investments drop when firms disagree more about the well-being of their future business conditions. These findings challenge the view that the dispersion of the firms' heterogeneous beliefs captures the concept of economic uncertainty, defined by a model of uncertainty shocks. The second chapter presents a general equilibrium model of heterogeneous firms subject to the real productivity uncertainty shocks and informational disagreement shocks. As firms cannot perfectly disentangle aggregate from idiosyncratic productivity because of imperfect information, information quality thus drives the wedge of difference between the unobserved productivity fundamentals, and the firms' beliefs about how productive they are. Distribution of the firms' beliefs is no longer perfectly aligned with the distribution of firm-level productivity across firms. This model not only explains why, at the macro and micro level, disagreement shocks are different from uncertainty shocks, as documented in Chapter 1, but helps reconcile a key challenge faced by the standard framework to study economic uncertainty: a trade-off between sizable business cycle effects due to changes in uncertainty, and the right amount of pro-cyclicality of firm-level investment rate dispersion, as measured by its correlation with the output cycles.

Faulkner revisited : narrating property, race, gender and history in William Faulkner's Go Down, Moses, Toni Morrison's Song of Solomon and Gloria Naylor's Mama Day

My thesis explores the formation of the subject in the novels of Faulkner’s Go Down, Moses, Toni Morrison’s Song of Solomon, and Gloria Naylor’s Mama Day. I attach the concept of property in terms of how male protagonists are obsessed with materialistic ownership and with the subordination of women who, as properties, consolidate their manhood. The three novelists despite their racial, gendered, and literary differences share the view that identity and truth are mere social and cultural constructs. I incorporate the work of Judith Butler and other poststructuralist figures, who see identity as a matter of performance rather than a natural entity. My thesis explores the theme of freedom, which I attached to the ways characters use their bodies either to confine or to emancipate themselves from the restricting world of race, class, and gender. The three novelists deconstruct any system of belief that promulgates the objectivity of truth in historical documents. History in the three novels, as with the protagonists, perception of identity, remains a social construct laden with distortions to serve particular political or ideological agendas. My thesis gives voice to African American female characters who are associated with love and racial and gender resistance. They become the reservoirs of the African American legacy in terms of their association with the oral and intuitionist mode of knowing, which subverts the male characters’ obsession with property and with the mainstream empiricist world. In this dissertation, I use the concept of hybridity as a literary and theoretical devise that African-American writers employ. In effect, I embark on the postcolonial studies of Henry Louise Gates, Paul Gilroy, W. E. B Du Bois, James Clifford, and Arjun Appadurai in order to reflect upon the fluidity of Morrison’s and Naylor’s works. I show how these two novelists subvert Faulkner’s essentialist perception of truth, and of racial and gendered identity. They associate the myth of the Flying African with the notion of hybridity by making their male protagonists criss-cross Northern and Southern regions. I refer to Mae Gwendolyn Henderson’s article on “Speaking in Tongues” in my analysis of how Naylor subverts the patriarchal text of both Faulkner and Morrison in embarking on a more feminine version of the flying African, which she relates to an ex-slave, Sapphira Wade, a volatile female character who resists fixed claim over her story and identity. In dealing with the concept of hybridity, I show that Naylor rewrites both authors’ South by making Willow Springs a more fluid space, an assumption that unsettles the scores of critics who associate the island with authenticity and exclusive rootedness.

Orthodox versus unorthodox care: A qualitative study on where rural women seek healthcare during pregnancy and childbirth in Southwest, Nigeria

Introduction Utilization of orthodox health facilities for maternal health services is determined by factors operating at the individual, household, community and state level. The prevalence of small family norm is one of the identified variables operating within the community which influences the decision of where to access care (orthodox/traditional). The objective of the study was to determine the use of orthodox versus unorthodox maternity healthcare and determinants among rural women in southwest Nigeria. Methods A qualitative study was done and involved three focus group discussions. A semi-structured interview guide was used to collect information from women of reproductive age group within a rural Local Government Area in Lagos state. Results Most of the women access some form of healthcare during pregnancy, orthodox, unorthodox or both. Those who patronize both services concurrently do so to benefit from the two as each has some unique features such as herbal concoctions for traditional, ultrasound and immunization of babies for orthodox. Traditional belief exerts a strong influence on decision of where to access maternal healthcare services. Actual place of delivery is determined by individual and household factors including financial resources. Conclusion Rural women utilize one or both orthodox and unorthodox maternal health services for different reasons. Ward Development Committees should be strengthened so as to reach the communities, educate and convince women to dispel myths which limit their use of orthodox care. Training and monitoring of Traditional Birth Attendants (TBAs) are vital to eliminate harmful practices. We also recommend improved financial access to orthodox healthcare.

Health, hygiene and biosecurity: tribal knowledge claims in the UK poultry industry

Since 1997 the world has been facing the threat of a human influenza pandemic that may be caused by an avian virus and the poultry industry around the globe has been grappling with the highly pathogenic strain of avian influenza H5N1, or in more informal terms bird flu. The UK poultry industry has lived with and through this threat and its consequences since 2005. This study investigates knowledge claims about health, hygiene and biosecurity as tools to ward off the threat from this virus. It takes a semi-ethnographic and discourse analytic approach to analyse a small corpus of semi-structured interviews carried out in the wake of one of the most publicised outbreaks of H5N1 in Suffolk in 2007. It reveals that claims about what best to do to protect flocks against the risk of disease are divided along lines imposed on the one hand by the structure of the industry and on the other by more 'tribal' lines drawn by knowledge and belief systems about purity and dirt, health and hygiene.
