Achieving quality teaching in developing countries : identifying factors that influence the delivery of quality teaching in primary schools in rural Cambodia : a research project presented in partial fulfilment of the requirements for the degree of Master of International Development, Institute of Development Studies, Massey University, Manawatu, New Zealand

At a global level the Education for All focus has shifted from years of schooling to the quality of education being attained. The delivery of quality education is dependent upon quality teaching. While there is no clear definition of quality teaching there are recognised characteristics which lend themselves to quality teaching and therefore are used as proxies to identify what constitutes a quality teacher. Of importance to this study is the fact these same recognised characteristics of what constitutes quality teaching and a quality teacher are reflected in the Ministry of Education, Youth and Sport in Cambodia (MoEYS) goals and teachers in Cambodia clearly identify with these characteristics. Drawing on a case study of Cambodia this research examines the influences that work upon a teacher to either positively influence the delivery of quality teaching or to negatively influence the same. While influences which positively and negatively impact quality teaching are wide ranging, some are definitely more influential than others. Hence there is a clear recognition of the importance of the provision of basic resources for education. The delivery of quality teaching requires basic physical infrastructure and resources such as teacher training, adequate teacher salaries and teaching materials. Without these basic resources a teacher is destined to fail in the delivery of quality teaching. This is particularly relevant in a developing country where the teachers are more likely to be working at a pre-professional level in terms of teaching skills, dependent upon teaching materials and reliant on basic classroom management skills. This is the case in Cambodia. Before any other influences become significant these fundamental needs must be met. There is also an important link between the health of both teachers and children and the delivery of quality teaching. Basic health needs must be met if the delivery of quality teaching is not to be undermined

Ciencia de las mujeres: Experiencias en la cadena textil desde los \u3ci\u3eayllus\u3c/i\u3e de Challapata

En el contexto de la crisis económica que atravesó Bolivia en los años ochenta, una comunidad de puna de pastores andinos, Livichuco, que forma parte integral del ayllu mayor de Qaqachaka, emprendió por iniciativa propia un proceso de mejoramiento de su producción textil, con un programa de rescate de los tintes naturales de la región. Con recursos mínimos, los comunarios compraron ollas y bateas metálicas, y comenzaron a preguntar a las personas mayores sobre sus conocimientos prácticos tradicionales en el ámbito de la tinción de textiles. Durante un período de diez años, y en coordinación con varias instituciones —incluida la nuestra: el Instituto de Lengua y Cultura Aymara (ILCA), de La Paz—, los socios de la asociación textil APSU (Artesanías para Seguir Unidos) han logrado mejorar los colores producidos por los tintes y diversificar su oferta de prendas para la venta. Ellos también construyeron en su comunidad un centro textil diseñado en una arquitectura propia, aunque experimental, con ventanas amplias para dejar entrar suficiente luz, donde las tejedoras de esta organización podían tejer acobijadas en la estación lluviosa y llevar adelante sus reuniones. Insistentemente, las mujeres de Apsu pidieron nuestro apoyo para continuar con sus actividades (véase las pág. 31-32)

Interculturalidad : ¿monólogo o diálogo? Pugnas lingüísticas y textuales en las reformas educativas en América Latina

The present essay perceives in the inauguration of the new Magister in Intercultural and Bilingual Education in Temuco, the initiation of a second stage of Educational Reforms in Latin America, this time with a regional rather than a global focus. In this context, the paper takes into account various criticisms of the first stage of reforms before considering new educational challenges. It questions above al1 the linguistic preconceptions behind the notions of "culture" and "interculturality" that are being used in current educational programmes, finding there the old debate between proponents of linguistic pragmatics and modern Saussurean linguistics. The author concludes that only a reevaluation of the constructive function of language at the heart of this debate will facilitate a new approach to two fundamental aspects of the second stage of educational reforms: interculturality and bilingual education

Enhanced heterogeneity of rpoB in Mycobacterium tuberculosis found at low pH.

OBJECTIVES: The aim of this study was to gain an insight into the molecular mechanisms of the evolution of rifampicin resistance in response to controlled changes in the environment. METHODS: We determined the proportion of rpoB mutants in the chemostat culture and characterized the sequence of mutations found in the rifampicin resistance-determining region of rpoB in a steady-state chemostat at pH 7.0 and 6.2. RESULTS: The overall proportion of rpoB mutants of strain H37Rv remained constant for 37 days at pH 7.0, ranging between 3.6 x 10(-8) and 8.9 x 10(-8); however, the spectrum of mutations varied. The most commonly detected mutation, serine to leucine mutation at codon 531 (S531L), increased from 40% to 89%, while other mutations (S531W, H526Y, H526D, H526R, S522L and D516V) decreased over the 37 day sampling period. Changing the pH from 7.0 to 6.2 did not significantly alter the overall proportion of mutants, but resulted in a decrease in the percentage of strains harbouring S531L (from 89% to 50%) accompanied by an increase in the range of different mutations from 4 to 12. CONCLUSIONS: The data confirm that the fitness of strains with the S531L mutation is greater than that of strains containing other mutations. We also conclude that at low pH the environment is permissive for a wider spectrum of mutations, which may provide opportunities for a successful mutant to survive

B-stability of numerical integrators on Riemannian manifolds

We propose a generalization of nonlinear stability of numerical one-step integrators to Riemannian manifolds in the spirit of Butcher's notion of B-stability. Taking inspiration from Simpson-Porco and Bullo, we introduce non-expansive systems on such manifolds and define B-stability of integrators. In this first exposition, we provide concrete results for a geodesic version of the Implicit Euler (GIE) scheme. We prove that the GIE method is B-stable on Riemannian manifolds with non-positive sectional curvature. We show through numerical examples that the GIE method is expansive when applied to a certain non-expansive vector field on the 2-sphere, and that the GIE method does not necessarily possess a unique solution for large enough step sizes. Finally, we derive a new improved global error estimate for general Lie group integrators

Dwarf Cepheids in the Carina Dwarf Spheroidal Galaxy

We have discovered 20 dwarf Cepheids (DC) in the Carina dSph galaxy from the analysis of individual CCD images obtained for a deep photometric study of the system. These short-period pulsating variable stars are by far the most distant (~100 kpc) and faintest (V ~ 23.0) DCs known. The Carina DCs obey a well-defined period-luminosity relation, allowing us to readily distinguish between overtone and fundamental pulsators in nearly every case. Unlike RR Lyr stars, the pulsation mode turns out to be uncorrelated with light-curve shape, nor do the overtone pulsators tend towards shorter periods compared to the fundamental pulsators. Using the period-luminosity (PL) relations from Nemec et al. (1994 AJ, 108, 222) and McNamara (1995, AJ, 109, 1751), we derive (m-M)_0 = 20.06 +/- 0.12, for E(B-V) = 0.025 and [Fe/H] = -2.0, in good agreement with recent, independent estimates of the distance/reddening of Carina. The error reflects the uncertainties in the DC distance scale, and in the metallicity and reddening of Carina. The frequency of DCs among upper main sequence stars in Carina is approximately 3%. The ratio of dwarf Cepheids to RR Lyr stars in Carina is 0.13 +/- 0.10, though this result is highly sensitive to the star-formation history of Carina and the evolution of the Horizontal Branch. We discuss how DCs may be useful to search effectively for substructure in the Galactic halo out to Galactocentric distances of ~100 kpc.Comment: 20 pages of text, 7 figure

Team boosting behaviours:Development and validation of a new concept and scale

In teams, some people are truly noticed when present, and sorely missed when absent. Often they are described as the “life of the party”, but in a formal team context, we refer to their behaviors as “team boosting behavior”. These behaviors have the potential to affect the team’s processes. In three consecutive studies, we conceptualized these behaviors and developed and validated a questionnaire to measure them. In Study 1, we defined team boosting behaviors as the extent to which team members exhibit mood-enhancing, energizing, and uniting behaviors, directed towards team members. In Study 2, we developed and validated an instrument to measure team boosting behaviors using a sample of team members in work and sports teams (N = 385). Results supported a three-factor structure and indicated positive relationships with conceptually similar constructs. In Study 3, we cross-validated the three-factor structure among the members of 120 work teams and offer evidence for convergent and criterion validity of the Team Boosting behavior scale. The behaviors related positively to a positive team climate, team work engagement, and leader-rated team performance. The scale provides a useful tool for future empirical research to study the role of individual team boosting behaviors in shaping team processes and outcomes
