    One of the most important decisions in the design of a questionnaire is the choice of the measurement scale(s). A common scale for questions about assessments/opinions is the Likert-type scale that ranges from 0 or 1 (worst assessment/disagreement) to 10 (highest assessment/agreement). Researchers often decide to recode this scale. In this context, a protocol is presented that facilitates this simplification task. The methodological sequencing of Factor Analysis and Cluster Analysis has several advantages. In addition to allowing the treatment of the original scale from two perspectives, it provides an optimal recoding with minimal loss of information. The application to a question taken from study No. 3325 of the Sociological Research Centre, related to the implications of Internet relationships with respect to face-to-face relationships in times of the pandemic, highlights the usefulness and versatility of the proposal.Una de las decisiones más importantes en el diseño de un cuestionario es la elección de la/s escala/s de medición. Una escala habitual en preguntas sobre valoraciones u opiniones es la escala tipo Likert, que oscila entre el 0 o el 1 (peor valoración/desacuerdo) y el 10 (máxima valoración/acuerdo). Es frecuente que los investigadores decidan recodificar esta escala. En este contexto, se presenta un protocolo que facilita esta tarea de simplificación. La secuenciación metodológica integrada por el análisis factorial y el análisis de clasificación presenta varias ventajas. Además de permitir el tratamiento de la escala original desde dos ópticas, proporciona una recodificación óptima con la mínima pérdida de información. La aplicación a una pregunta extraída del estudio n.º 3325 del Centro de Investigaciones Sociológicas, relativa a las implicaciones de las relaciones por Internet respecto a las presenciales en tiempos de pandemia, pone de manifiesto la utilidad y versatilidad de la propuesta

    British Women Travellers And The Harems: Liberties, Enslavement and Domesticity

    No full text
    This thesis examines the complex perspective of a woman traveller. Wortley Montagu, Martineau, Burton and their contemporaries, represented the harem through various lenses. The Oriental harem has fascinated Western civilization since time immemorial. This sacred place, reserved for the women and children of the Muslim household, had long been a terra incognita to British outsiders, until the publication of Lady Mary Wortley Montagu’s (1689-1762) Turkish Embassy Letters (1763), which gave impetus to a whole tradition of travel writings, particularly harem accounts, penned by British women. The aristocratic Wortley Montagu recasts Turkish women from their previous Western image as over-sexed and soulless beings to idealized domestic goddesses, living in an ideal world, the harem. Harriet Martineau(1802-1876) , travelled to the Ottoman Empire more than a century after Wortley Montagu’s residency in Oriental lands. Martineau was a rare talent. She was an accomplished journalist and a pioneering figure in Western sociology. She spent her life validating a place for herself and her sex in a patriarchal and male-dominated society; she earned her own keeping, and lived independently. Martineau related her eastern experience in Eastern Life: Past and Present (1848), in which the Oriental harem figures very little. Martineau pitied the women she encountered in Egypt, and depicted them as slaves of a corrupt system, the harem and the practice of polygamy. My thesis ends with the travel writings of Lady Isabel Burton (1831-1896) whose view of the Oriental women she met in Syria is the most tempered. Her Inner Life of Syria, Palestine and the Holy Lands: from my Private Journal (1875) displays a tolerance of other cultures and a move toward moral and cultural relativisms. Each of the women considered in this thesis formed her own harem, projecting on to this distant Oriental structure her fears, hopes and desires. Wortley Montagu’s harem was a utopia for women only. The Victorian Martineau opined that the Oriental harem was a hell on earth. Lady Isabel Burton constructed a happy medium between the two. Although at times ambivalent towards the Syrian women she encountered, she partook in their customs and manners, particularly public bathing, smoking and other Eastern indulgences. Her attitude illustrates that the British home and the Oriental harem are not so dissimilar, bridging the gap between us and them

    Análisis exploratorio de estructuras temporales desde la óptica de tablas múltiples. Una aplicación // Exploratory Analysis of Temporal Structures from the Multiple Tables Optic. An Application

    En este trabajo se presenta un enfoque alternativo a los gráficos habituales de series temporales para su análisis comparativo exploratorio. Al disponer de varias series temporales medidas en diversos contextos, sugerimos su estructura en tablas múltiples para estudiar de forma adecuada sus similitudes y diferencias. El Análisis Factorial Múltiple (AFM) es la técnica seleccionada como la más idónea para alcanzar los objetivos planteados, a través de sus medidas numéricas y gráficas. Este enfoque del AFM supone una novedad, ya que en otros estudios el tiempo ha sido utilizado como criterio de estructuración de los grupos y no como unidad estadística como se plantea en este artículo. Una aplicación empírica a partir de datos mensuales, de los últimos 10 años, relativos a tres indicadores estrechamente relacionados con el turismo, desde el punto de vista de la demanda, y medidos en siete territorios nacionales, permite evidenciar la versatilidad y potencialidad de la propuesta. ------------------------------------ In this work we present an alternative approach to the usual graphics of time series for its comparative exploratory analysis. By having several time series measures in various contexts, we suggest its structure in multiple tables to study adequately their similarities and differences. The Multiple Factorial Analysis (MFA) is the technique that is selected as the most suitable for achieving the stated objectives, through their numerical measures and graphs. This approach of AFM is a novelty, since in other studies the time has been used as a criterion for structuring groups and not as statistical unit as discussed in this article. An empirical application from monthly data, of the last 10 years, relating to three indicators closely related to tourism, from the point of view of demand, and measured in seven national territories, makes evident the versatility and potential of the proposal

    The first Australian palynologist: Isabel Clifton Cookson (1893–1973) and her scientific work

    No full text
    Isabel Clifton Cookson (1893–1973) of Melbourne, Australia, was one of that country’s first professional woman scientists. She is remembered as one of the most eminent palaeontologists of the twentieth century and had a distinguished research career of 58 years, authoring or co-authoring 93 scientific publications. Isabel worked with great distinction on modern and fossil plants, and pioneered palynology in Australia. She was a consumate taxonomist and described, or jointly described, a prodigious total of 110 genera, 557 species and 32 subspecific taxa of palynomorphs and plants. Cookson was a trained biologist and initially worked as a botanist during the 1920s. At the same time she became interested in fossil plants and then, Mesozoic–Cenozoic terrestrial (1940s–1950s) and aquatic (1950s–1970s) palynomorphs. Cookson’s research into the late Silurian–Early Devonian plants of Australia and Europe, particularly the Baragwanathia flora, between the 1920s and the 1940s was highly influential in the field of early plant evolution. The fossil plant genus Cooksonia was named for Isabel in 1937 by her principal mentor in palaeobotany, Professor William H. Lang. From the 1940s Cookson focussed on Cenozoic floras and, with her students, elucidated floral affinities by comparative analyses of micromorphology, anatomy and in situ pollen/spores between fossil and extant taxa. This led to an interest in pre-Quaternary and Quaternary terrestrial pollen and spores; hence Isabel was the first palynologist in Australia. Her work on Paleogene and Neogene pollen and spores during the 1940s and 1950s provided incontrovertible evidence of the former widespread distribution of many important elements of Southern Hemisphere floras. During the early 1950s, while approaching her 60th year, Isabel turned her attention to marine palynomorphs. She worked with great distinction with Georges Deflandre and Alfred Eisenack, and also as a sole author, on acritarchs, dinoflagellate cysts and prasinophytes from the Jurassic to Quaternary of Australia and Papua New Guinea. She also co-authored papers on aquatic palynomorphs with Lucy M. Cranwell, Norman F. Hughes and Svein B. Manum. Isabel Cookson laid out the taxonomic basis for the study of Australasian Mesozoic and Cenozoic marine palynofloras by establishing, or jointly establishing, 76 genera and 386 species of marine microplankton. Her studies throughout her career, although especially in marine palynology, concentrated largely on taxonomy. However, she was one of the first palynologists to demonstrate the utility of dinoflagellate cysts for relative age dating and correlation in geological exploration

    On the Symbols of Strictly m-Null Elementary Operators

    No full text
    This paper extends the previous work by the author on m-null pairs of operators in Hilbert space. If an elementary operator L has elementary symbols A and B that are p-null and q-null, respectively, then L is (p+q−1)-null. Here, we prove the converse under strictness conditions, modulo some nonzero multiplicative constant—if L is strictly (p+q−1)-null, then a scalar λ≠0 exists such that λA is strictly p-null and λ−1B is strictly q-null. Our constructive argument relies essentially on algebraic and combinatorial methods. Thus, the result obtained by Gu on m-isometries is recovered without resorting to spectral analysis. For several operator classes that generalize m-isometries and are subsumed by m-null operators, the result is new

    Attualità di un classico. Rileggendo "The Child Savers" di Tony Platt

    No full text
    The essay reconstructs the history of the different editions of The Child Savers by Anthony M. Platt, not sticking to a merely philological perspective, but trying to highlight the theoretical transformations that pass through it in its three different editions (1969, 1977 and 2007). This is an intellectual evolution that is closely linked to the political biography of the Author and with the modulations of his research. Both the stratigraphy of meanings that characterizes Platt’s work and the relevance of his perspective on the topic of juvenile justice are highlighted. In fact, more than fifty years later, his work continues to spark discussions among generations of scholars, as demonstrated by the papers published in this sectio
