Recovering S1S^1-invariant metrics on S2S^2 from the equivariant spectrum

We prove an inverse spectral result for $S^1$-invariant metrics on $S^2$ based on the so-called asymptotic equivariant spectrum. This is roughly the spectrum together with large weights of the $S^1$ action on the eigenspaces. Our result generalizes an inverse spectral result of the first and last named authors, together with Victor Guillemin, concerning $S^1$-invariant metrics on $S^2$ which are invariant under the antipodal map. We use higher order terms in the asymptotic expansion of a natural spectral measure associated with the Laplacian and the $S^1$ action.Comment: 16 pages; minor revisions throughout following comments from referee

South Texas journalism: A case study of historical agenda-setting, 1861-1865

In a span of two decades, agenda-setting has been a topic of interest in the communication field. Despite this interest, agenda-setting studies lack attempts to make the concept of agenda-setting useful in an historical context. This content analysis was designed to determine what agenda South Texas newspapers set with the Civil War coverage between January 1861 and May 1865. The process of agenda-setting is described by quantity and kind of war coverage. The findings of this thesis lend support to the research question that South Texas newspapers did make the Civil War part of their agenda. This thesis indicates that 39 percent of South Texas newspapers expressed an interest in covering the Civil War

A comprehensive study of the effect of meteorological conditions on fruit abscission and metamitron thinning efficacy in Malus domestica Borkh

Doutoramento em Engenharia Agronómica / Instituto Superior de Agronomia. Universidade de LisboaMetamitron is an apple (Malus domestica Borkh.) fruit thinner that acts by reducing the photosynthetic capacity of trees. Thinning is a common practice among apple growers however, the effect of meteorological conditions, per si, and after metamitron spraying, is far from elucidated. In order to investigate the triggered physiological and biochemical processes, trials with shading nets (SN) during 5 days and high nighttime temperature (HNT) during 5 nights, along with high humidity (HH) for 3 h prior spraying were set in three locations, within 3 years. Lower irradiance caused a momentaneous photosynthetic decrease that led to reduced levels of leaf sucrose and sorbitol and consequent increases in fruit abscission rates. HNT pathway is a slight increment in the respiratory mechanisms, but mainly in the whole tree metabolic activity, finally resulting in a shortage in sucrose and sorbitol levels, reducing fruit growth and promoting higher abscission rates. Metamitron acts through a photosynthetic inhibition, including reductions in RuBisCO total activity, translating in less CH production. In addition, it stimulates vegetative growth, consuming CH and slowing down fruit growth rate, and finally enhancing of abscission. The combined treatments resulted in the strongest thinning efficacy, through a suppression of the CH production caused by metamitron in combination with low radiation and or through enhanced expenditure cause by HNT, frequently over-thinning. The effect of HH may enhance fruit drop under humid climates and in younger trees, more susceptible to variations in CH content. This work shows meteorological conditions, namely cloudy days, periods of HNT and increased humidity levels, may affect metamitron thinning efficacy and must be considered in order to decide which rate to apply to achieve an optimum crop loadN/

Female Land Rights and Rural Household Incomes in Brazil, Paraguay and Peru

This paper explores the determinants of female land rights and their impact on household income levels among owner-operated farms in Brazil, Paraguay and Peru. Previous studies in Latin America suggest that the gender of the household head is not a significant predictor of household income, not unsurprising given the ambiguities with which self-declared headship is associated. We hypothesize that female land rights, by increasing women's options, are a positive determinant of household income, but given the disadvantages that they face as farmers, that their land rights will more likely impact upon off-farm rather than farm income. Regression analysis indicates that female land rights are positively related to off-farm income in Peru and Paraguay, but significantly so only in the case of dual-headed households in Peru where the bargaining power thesis is operative. They are negatively associated with farm income in both countries and with farm revenue in Brazil.Gender, Land Rights, Household Income, Female-headed Households, Intrahousehold Bargaining Power, Latin America

Del 'Bogotazo' al Día Nacional de la Memoria y Solidaridad con las Víctimas : Los nuevos sentidos del 9 de abril en Colombia

Hasta el 2011, todos los 9 de abril en Colombia se conmemoraba el asesinato de Jorge Eliécer Gaitán, líder político que promovió cambios importantes en el país pero es con la promulgación de la Ley de Víctimas y Restitución de Tierras en junio de ese año, que esta fecha adquiere un nuevo sentido en el calendario: El Día Nacional de la Memoria y Solidaridad con las Víctimas. Luchas de memorias, resignificaciones y olvidos, se juntan en un solo día en un país que hace memoria de su pasado presente por ello, el presente artículo se pregunta sobre¿cómo sería recibida la implementación del 9 de abril como fecha emblemática?, ¿cómo agrupar o reunir en un mismo día tantas memorias juntas de sucesos ocurridos en tiempos diferentes y lugares distintos?, ¿quién recordaría y qué?Fil: De la Rosa González, Diana.

Penerapan Pengembangan Permainan Congklak Sebagai Media Pembelajaran Pada Materi Bangun Datar Di Kelas III SD

Ethnomathematics is a form of mathematics based on culture. Through the application of ethnomathematics in education, especially mathematics education, it is hoped that later students can better know and understand our own culture and educators can also more easily instill cultural values ​​themselves in students, so that cultural values ​​that should be part of the nation's character can be embedded early on in students. One of them is by using the traditional game of Congklak. One of the games that can be used in learning mathematics is the traditional game of congklak which is considered suitable in the material of two-dimentional figure where in it’s section there are several shapes of two-dimentional figure, such as circles and rectangles. The game is not only used as a learning medium, but students can get to know more about the traditional game of congklak and so that the traditional game of congklak can continue to be preserved. Schools have a variety of learning media, but not all of these media contain elements of Indonesian culture, especially for mathematics. The researcher also uses a qualitative method with an ethnographic approach and a descriptive method using the ADDIE teaching material development model to explain the results of the research that has been done. The application of this media is said to have positive results from the field results obtained by researchers and from the results of interviews conducted afterwards. The use of this media can in fact be applied to learning media in the classroom because it’s use is easy and fun for students

Exemplifying mathematics teacher’s specialised knowledge in university teaching practices

International audienceExtant research on the teachers’ knowledge includes limited studies focusing on teachers at university level. In this work, based on the Mathematics Teacher’s Specialised Knowledge (MTSK) model and through an instrumental case study, knowledge of a lecturer in a real analysis course for prospective mathematics teachers is analyzed. We exemplified lecturer knowledge in different subdomains of the MTSK model. These results contribute to the understanding and characterization of the components of mathematics teacher’s specialised knowledge at the university level
