The gender wage gap is well studied in developed countries; however, recently it has generated much interest in developing countries. This thesis addresses three issues regarding the gender wage gap in Bangladesh. Firstly, it explores the wage determinants for formal public and private sector employees in Bangladesh and examines the gender pay gap. This is the first time different decomposition methods have been used to compare the sources of the gender wage gap as well as any potential discrimination effect in the formal sector of the Bangladeshi labour market. These decomposition methods are: the original Oaxaca (1973) and Blinder (1973) decomposition methods, the Neumark (1988), Cotton (1988), and Reimers (1983) methods, and the extended Oaxaca method including both the employment selection and the double selection correction in the wage equation. In addition to mentioned methods, to quantify the gender wage gap in monetary terms, a recently developed ‘simulated change’ approach by Olsen and Walby (2004) is also applied for the first time to the Bangladeshi data. By using the Labour Force Survey 2005-06, BBS (LFS 2005-06) data results show formal sector female employees earn about 32.1 per cent less than their male counterparts. Without considering the selection correction, a large range of human capital, demographic and labour market related variables are explained less than half of the total gender wage gap (21 to 46 per cent of the total wage gap) and the major part of the wage gap is unexplained (54 to 79 per cent of the total wage gap). This could partly be attributed to discrimination. Using the double selection correction method, the decomposition results changed where a small part of the wage gap was explained by the measured characteristics (only nine per cent of the total wage gap) and a major part is attributed to the discrimination and selection effect. The selection effect also reveals that exclusion of the double selection correction might lead to an overestimation of the gender wage gap in the formal sector of Bangladesh. In addition, results based on the Olsen and Walby (2004) simulation method show that, if the other characteristics of male and female employees were similar, ‘being female’ is sufficient, to generate significantly lower wages than males in the formal sector. If females in the workplace are treated as males, without considering any other endowment increases, females could increase their earnings by 4095.3 Taka1 per year. Results also indicate that not only endowment differences in human capital and work experience related variables were important, but discrimination appears to play a significant role in the total wage gap throughout the formal sector of the Bangladeshi labour market. Secondly, the study investigates whether public sector employees enjoyed a wage premium or not, compared to the private sector and whether the gender wage gap is greater in the public sector. In addition, the research considered whether there was an impact from the inclusion of the different selection correction terms in the wage equation. In Bangladesh, public sector employees have, on average, a 60 per cent wage premium over the private sector. Using both the original Oaxaca and the extended Oaxaca methods, where selection effect is partly captured by both explained and unexplained components, and using the public sector wage structure as the basis of the non-discriminatory wage structure, these methods revealed a considerably larger portion of explained (72 - 93 per cent of the total wage gap) and a smaller portion of unexplained part of the wage gap. However, if the selection correction is considered as another component of the decomposition outcome then the major portion of the total public and private sectors wage gap is justified (explained) by the effect of the selection correction and unexplained factors. Furthermore, a large part of the wage premium exists in favour of public sector female employees compared to males and the gender wage gap is lower in the public sector than the private sector. Finally, this study compares the gender wage gap of five different occupations. The gender wage gap is associated with labour market rigidities where one of the important factors is occupational segregation where females are disproportionately distributed in occupations resulting in lower earnings. The largest gender wage gap was found in agriculture, forestry, fisheries, production and transport labour jobs (56.4 per cent) and the lowest in the professional, technical administrative and managerial jobs (22.1 per cent). Substantial differences are found in the size of the endowment gap across occupations and larger variations occurred in the adjusted wage gap which varied from 21.4 per cent in sales and service occupations, to 100 per cent in professional and technical jobs (the highest). This too can be partly explained by discrimination. A reduction in the gender wage gap is expected not only to increase national income, but also to reduce poverty and lead to better outcomes for future generations. National policy should aim to reduce the gender wage gap and achieve gender wage equality in the formal sector; for example through a targeted program to remove the gender differences in education and to reduce the skill difference, with a better child care policy to encourage labour force retention and increased labour market experience for female employees, with anti-discriminatory policies and the enforcement of existing antidiscrimination policies, and a more equal distribution of males and females across occupations.

This thesis investigates how seven communities in a subregion of the Sierra Norte of Oaxaca are conserving high forest cover in the absence of national protected areas. To conduct this study I relied on archival research and the review of community documents, focus group interviews and land use transects to explore historical and current land use. I found that communities have conserved 88.34% of the subregion as forest cover, or 58,596 hectares out of a total territory of 66,264 hectares. Analysis suggests that the communities have undergone a historical transition from more passive conservation to more active, conscious conservation particularly in the last decade. This thesis further contends that communities deserve additional financial compensation for this active conservation of globally important forests for biodiversity conservation and that exercises in systematic conservation planning ignore the reality that existing biodiversity conservation in the subregion is associated with community ownership.

Dada la persistencia de las diferencias en ingresos laborales por regiones en Colombia, el presente artículo propone cuantificar la magnitud de este diferencial que es atribuida a la diferencia en estructuras de mercado laboral, entendiendo esta última como la diferencia en los retornos a las características de la fuerza laboral. Para ello se propone el uso de un método de descomposición del tipo Oaxaca- Blinder y se compara a Bogotá –la ciudad con mayores ingresos laborales- con otras ciudades principales. Los resultados obtenidos al conducir el ejercicio de descomposición muestran que las diferencias en estructura están a favor de Bogotá y que estas explican más de la mitad de la diferencia total, indicando que si se quieren reducir las disparidades de ingresos laborales entre ciudades no es suficiente con calificar la fuerza laboral y que es necesario indagar por las causas que hacen que los retornos a las características difieran entre ciudades.

OBJETIVO: Analizar la vulnerabilidad para ITS/VIH entre mujeres Purépechas y Zapotecas unidas en concubinato con varones que practican sexo sin protección. MÉTODOS: Estudio etnográfico realizado en febrero del 2004 y en diciembre del 2005 en localidades indígenas de Michoacán y Oaxaca, Mexico. Estos son entidades con niveles altos de expulsión migratoria, rezago comunitario y casos registrados de VIH/SIDA. Se entrevistaron en profundidad a 91 personas: migrantes temporales (24), mujeres indígenas (33), autoridades locales (20) y personal de salud (14). RESULTADOS: La ruralización del ITS/VIH puede relacionarse con las prácticas de iniciación sexual femeninas pero sobre todo con el miedo del migrante a que su concubina tenga relaciones extra-conyugales en su ausencia. El embarazo y la crianza son recursos masculinos de control de las esposas. CONCLUSIONES: La migración de retorno implica formas de vulnerabilidad para las mujeres indígenas en las localidades estudiadas, cuya sexualidad tiene un remarcado carácter reproductivo. Es necesario implementar políticas de prevención para ITS/VIH dirigidas a fortalecer derechos sexuales y reproductivos de las mujeres y que tomen en cuenta aspectos de identidad sexual masculina.

Salvia divinorum Epling & Jativa is an hallucinogenic mint traditionally used for curing and divination by the Mazatec Indians of Oaxaca, Mexico. Young people from Mexican cities were reported to smoke dried leaves of S. divinorum as a marijuana substitute. Recently, two S. divinorum specimens were seized in a large-scale illicit in-door and out-door hemp plantation. Salvinorin A also called divinorin A, a trans-neoclerodane diterpene, was identified in several organic solvent extracts by gas chromatography-mass spectrometry. The botanical identity of the plant was confirmed by comparing it to an authentic herbarium specimen. More plants were then discovered in Swiss horticulturists greenhouses. All these data taken together suggest that many attempts exist in Switzerland to use S. divinorum as a recreational drug. This phenomenon may be enhanced because neither the magic mint, nor its active compound are banned substances listed in the Swiss narcotic law.

La población femenina y la indígena del Ecuador han presentado continuamente desigualdades de ingresos respecto a la población masculina y a la no indígena, respectivamente. El presente trabajo reporta que una parte de las diferencias salariales a favor de los hombres y de la población no indígena es resultado de la discriminación salarial por razones de género y etnia. Este resultado se ha obtenido estimando ecuaciones mincerianas de ingresos corrigiendo el problema de se sgo de selección muestral y utilizando la metodología de descomposición de las brechas salariales de Oaxaca (1973) y Newmak (1988) también corregidas por el problema de sesgo de selección muestral.

El propósito de esta investigación fue estudiar las relaciones ambientales de disponibilidad de humedad, con las características anatómicas del sistema de conducción de agua y estomático, en cinco genotipos de duraznos mexicanos con diferentes orígenes (Jalatzingo y Misantla, Veracruz; Temascaltepec, México; Tulancingo, Oaxaca; Sombrerete, Zacatecas), un almendro y el portainjerto Nemaguard. Fueron caracterizados anatómicamente brotes, hojas y estomas de plántulas de seis meses de edad, mediante 25 caracteres. El almendro y el portainjerto Nemaguard presentaron diferencias con respecto a los duraznos, los cuales tuvieron mayor similitud, aunque mantuvieron una separación acorde con su origen. Los caracteres que diferenciaron los grupos fueron: densidad estomática, grosor de la epidermis superior, número, frecuencia y perímetro de vasos, el índice de vulnerabilidad de la nervadura central, y el porcentaje de médula, xilema y floema del brote. Las condiciones de disponibilidad de humedad del origen presentaron fuerte asociación con las características anatómicas estudiadas, debido a que los ambientes con mayor déficit de humedad (Tulancingo y Sombrerete) presentaron mayor tamaño y menor frecuencia de vasos de xilema, así como bajo porcentaje de xilema y floema en brote, lo que puede interpretarse como adaptaciones de resistencia a sequía. La zona donde es rara la ocurrencia de sequía (Jalatzingo) presentó características opuestas.

The purposes of this study were to determine the distribution and climatic patterns of current and future physic nut (Jatropha curcas) cultivation regions in Mexico, and to identify possible locations for in vivo germplasm banks establishment, using geographic information systems. Current climatic data were processed by Floramap software to obtain distribution maps and climatic patterns of regions where wild physic nuts could be found. DIVA-GIS software analyzed current climatic data (Worldclim model) and climatic data generated by CCM3 model to identify current and future physic nut cultivation regions, respectively. The distribution map showed that physic nut was present in most of the tropical and subtropical areas of Mexico, which corresponded to three agroclimatic regions. Climate types were Aw2, Aw1, and Bs1, for regions 1, 2 and 3, respectively. Nontoxic genotypes were associated with region 2, and toxic genotypes were associated with regions 1 and 3. According to the current and future cultivation regions identified, the best suitable ones to establish in vivo germplasm collections were the coast of Michoacán and the Isthmus of Tehuantepec, located among the states of Veracruz, Oaxaca and Chiapas.
