PREFACE The Third International Mathematics and Science Study (TIMSS), sponsored by the International Association for the Evaluation of Educational Achievement (IEA) and the g- ernments of the participating countries, is acomparative study of education in mathematics and the sciences conducted in approximately 50 educational systems on six continents. The goal of TIMSS is to measure student achievement in mathematics and science in participating countries and to assess some of the curricular and classroom factors that are related to student learning in these subjects. The study is intended to provide educators and policy makers with an unpar- leled and multidimensional perspective on mathematics and science curricula; their implem- tation; the nature of student performance in mathematics and science; and the social, econ- ic, and educational context in which these occur. TIMSS focuses on student learning and achievement in mathematics and science at three different age levels, or populations. • Population 1 is defined as all students enrolled in the two adjacent grades that contain the largest proportion of 9-year-old students; • Population 2 is defined as all students enrolled in the two adjacent grades that contain the largest proportion of 13-year-old students; and • Population 3 is defined as all students in their final year of secondary education, incl- ing students in vocational education programs. In addition, Population 3 has two “specialist” subpopulations: students taking advanced courses in mathematics (mathematics specialists), and students taking advanced courses in physics (physics specialists).

Full of drama, dedication, and humor, this book narrates the author’s often frustrating experiences working as an experimental physicist in Cuba after the disintegration of the so-called socialist block. Lacking finance and infrastructure, faced with makeshift equipment, unpredictable supplies, and unreliable IT, Altshuler tells how he and his students overcame numerous challenges to make novel and interesting contributions to several fields of science. Along the way, he explains the science - from studies of ant colonies to superconductivity - either qualitatively or quantitatively, but always at a level fully understandable to an undergraduate student of natural sciences or engineering. An even wider audience, however, may skip the technical sections without missing the essence. With numerous anecdotes, photographs and the author’s own delightful cartoons, the book tells a remarkable, and often amusing story of how successful science can be performed against all odds.
Syphilis was a prevalent affliction in the era of the Americas’ colonization, creating widespread anxiety that is indicated in the period’s literature across numerous fields. Reflecting Spaniards’ political prejudices of the period, it was alternately labeled "mal francés" or "el mal de las Indias." Sifilografía offers a cultural history that traces syphilis and its consequences in the transatlantic Spanish-speaking world throughout the long eighteenth century. Juan Carlos González Espitia charts interrelated literary, artistic, medical, and governmental discourses, exploring how fears of the disease and the search for its cure mobilized a transoceanic dialogue that forms an underside of Enlightenment narratives of progress. Through a narrative revealing the transformation and retooling of ideas related to syphilis as a bodily contagion, González Espitia demonstrates the Spanish-speaking world’s crucial relevance to a global understanding of the period in the context of current reassessments of Enlightenment thought. Broad in its scope, the book incorporates an extensive corpus of medical treatises, literary essays, poems, novels, art, and governmental documents. The rich overlapping matrix of authors and texts broached subvert the idea of a homogeneous interpretation of syphilis and contributes to the rediscovery of the wide-ranging historical, cultural, and philosophical impact of this disease in the Spanish-speaking world. Sifilografía seeks to open a productive dialogue with other area studies about the disparate meanings of science and Enlightenment.
