    <p>Abstract</p> <p>Background</p> <p>Corruption pervades educational and other institutions worldwide and medical schools are not exempt. Empirical evidence about levels and types of corruption in medical schools is sparse. We conducted surveys in 2000 and 2007 in the medical school of the Autonomous University of Guerrero in Mexico to document student perceptions and experience of corruption and to support the medical school to take actions to tackle corruption.</p> <p>Methods</p> <p>In both 2000 and 2007 medical students completed a self-administered questionnaire in the classroom without the teacher present. The questionnaire asked about unofficial payments for admission to medical school, for passing an examination and for administrative procedures. We examined factors related to the experience of corruption in multivariate analysis. Focus groups of students discussed the quantitative findings.</p> <p>Results</p> <p>In 2000, 6% of 725 responding students had paid unofficially to obtain entry into the medical school; this proportion fell to 1.6% of the 436 respondents in 2007. In 2000, 15% of students reported having paid a bribe to pass an examination, not significantly different from the 18% who reported this in 2007. In 2007, students were significantly more likely to have bribed a teacher to pass an examination if they were in the fourth year, if they had been subjected to sexual harassment or political pressure, and if they had been in the university for five years or more. Students resented the need to make unofficial payments and suggested tackling the problem by disciplining corrupt teachers. The university administration made several changes to the system of admissions and examinations in the medical school, based on the findings of the 2000 survey.</p> <p>Conclusion</p> <p>The fall in the rate of bribery to enter the medical school was probably the result of the new admissions system instituted after the first survey. Further actions will be necessary to tackle the continuing presence of bribery to pass examinations and for administrative procedures. The social audit helped to draw attention to corruption and to stimulate actions to tackle it.</p

    Truncation Effects in the Functional Renormalization Group Study of Spontaneous Symmetry Breaking

    We study the occurrence of spontaneous symmetry breaking (SSB) for O (N) models using functional renormalization group techniques. We show that even the local potential approximation (LPA) when treated exactly is sufficient to give qualitatively correct results for systems with continuous symmetry, in agreement with the Mermin-Wagner theorem and its extension to systems with fractional dimensions. For general N (including the Ising model N = 1) we study the solutions of the LPA equations for various truncations around the zero field using a finite number of terms (and different regulators), showing that SSB always occurs even where it should not. The SSB is signalled by Wilson-Fisher fixed points which for any truncation are shown to stay on the line defined by vanishing mass beta functions

    Interfacial and Foaming Properties of Two Types of Total Proteose-Peptone Fractions

    Total proteose-peptone (TPP) fractions were extracted from skimmed milk (UHT) and whey protein concentrate (WPC) on a laboratory scale. Protein solutions (0.1 %, 0.5 %, and 1 % w/w) were characterized as function of pH: 4.0, 4.6–4.7 (native pH), and 7.0. Their foaming capacities and stabilities were studied. Beforehand, the surface properties that govern them were investigated, notably the kinetics of adsorption and mechanical properties of monolayer films at the air–water interface involved in the formation and the stability of foams respectively. The TPP extracted from skimmed milk showed the lowest values as well as a significant reduction in surface tension and presented a good mechanically resistant film. The TPP extracted from WPC presented a better foaming capacity and stability which was unexpected. However, foaming properties and surface properties of TPP fractions depended on the pH. The considerable influence of extraction source and method on proteosepeptone’s properties were highlighted

    Patterns and Drivers of Communal Conflict in Kenya

    No full text
    This chapter analyzes patterns of communal conflict – i.e., violent conflicts between non-state groups which are organized based on communal identities – in Kenya. The politicized nature of ethnicity in Kenya, and the fact that both elections and land tenure are closely associated with ethnic identity, are highlighted as key factors explaining the prevalence of violent communal conflict. After discussing the main patterns of conflict since 1989, the chapter goes on to identify four main drivers of conflict: electoral politics, cattle raiding, local resources, and boundaries and local authority. The specific dynamics at play in different conflicts vary, and empirical examples illustrate how the precise way that different conflict drivers interact is different from case to case. The chapter also discusses different strategies by state and non-state actors to address and resolve communal conflicts, and how devolution – the decentralization of significant power to the local level under the 2010 constitution – has affected communal conflicts. As the discussion of devolution illustrates, a major point is that while communal conflicts in general should be seen against the background of a state and a political culture where ethnicity is strongly politicized, the impact of national-level political dynamics on communal conflicts will vary from case to case
