Forward logistic regression for earth-flow landslide susceptibility assessment in the Platani river basin (southern Sicily, Italy)

Forward logistic regression has allowed us to derive an earth-flow susceptibility model for the Tumarrano river basin, which was defined by modeling the statistical relationships between an archive of 760 events and a set of 20 predictors. For each landslide in the inventory, a landslide identification point (LIP) was automatically produced as corresponding to the highest point along the boundary of the landslide polygons, and unstable conditions were assigned to cells at a distance up to 8m. An equal number of stable cells (out of landslides) was then randomly extracted and appended to the LIPs to prepare the dataset for logistic regression. A model building strategy was applied to enlarge the area included in training the model and to verify the sensitivity of the regressed models with respect to the locations of the selected stable cells. A suite of 16 models was prepared by randomly extracting different unoverlapping stable cell subsets that have been appended to the unstable ones. Models were finally submitted to forward logistic regression and validated. The results showed satisfying and stable error rates (0.236 on average, with a standard deviation of 0.007) and areas under the receiver operating characteristic (ROC) curve (AUCs) (0.839 for training and 0.817 for test datasets) as well as factor selections (ranks and coefficients). As regards the predictors, steepness and large-profile and local-plan topographic curvatures were systematically selected. Clayey outcropping lithology, midslope drainage, local and midslope ridges, and canyon landforms were also very frequently (from eight to 15 times) included in the models by the forward selection procedures. The model-building strategy allowed us to produce a performing earth-flow susceptibility model, whose model fitting, prediction skill, and robustness were estimated on the basis of validation procedures, demonstrating the independence of the regressed model on the specific selection of the stable cells

Writing materiality into management and organization studies through and with Luce Irigaray

YesThere is increasing recognition in management and organization studies of the importance of materiality as an aspect of discourse, while the neglect of materiality in post-structuralist management and organization theory is currently the subject of much discussion. This article argues that this turn to materiality may further embed gender discrimination. We draw on Luce Irigaray’s work to highlight the dangers inherent in masculine discourses of materiality. We discuss Irigaray’s identification of how language and discourse elevate the masculine over the feminine so as to offer insights into ways of changing organizational language and discourses so that more beneficial, ethicallyfounded identities, relationships and practices can emerge. We thus stress a political intent that aims to liberate women and men from phallogocentrism. We finally take forward Irigaray’s ideas to develop a feminist écriture of/for organization studies that points towards ways of writing from the body. The article thus not only discusses how inequalities may be embedded within the material turn, but it also provides a strategy that enriches the possibilities of overcoming them from within

PELIGROSIDAD A LOS MOVIMIENTOS DE LADERA EN LA VERTIENTE MERIDIONAL DE SIERRA NEVADA (GRANADA) A PARTIR DE LA ESTIMACIÓN MULTI-TÉCNICA DE LA ACTIVIDAD

El presente trabajo aborda la cartografía de la susceptibilidad y la peligrosidad a los movimientos de ladera, en un ambiente montañoso, con información limitada sobre su actividad. El análisis y validación de la susceptibilidad se realizada mediante un modelo elaborado a partir del ModelBuilder™ de ArcGIS basado en el Método de la Matriz en un SIG. Dicho modelo necesita una cartografía previa de los movimientos, un MDE y un análisis discriminante de los factores determinantes de la estabilidad. Los datos del análisis reflejan que el 15% de la zona estudiada muestra una susceptibilidad a los movimientos de moderada a muy alta que, a su vez, coincide con lugares donde se encuentran la mayoría de las infraestructuras públicas de la región. Además, los valores registrados en la validación mediante el grado de ajuste están por encima del 83% para las zonas de susceptibilidad alta y muy alta. Estas zonas que presentan un mayor grado de susceptibilidad y, por tanto, una mayor exposición potencial al riesgo, son las seleccionadas para el análisis detallado de la peligrosidad. El principal problema, que, por otra parte, suele ser generalizado en este tipo de áreas para la estimación de la frecuencia con la que se suceden movimientos de ladera, es la falta de información sobre su ocurrencia. Por tanto, y con el objetivo de obtener la mayor información posible, los datos relativos a la actividad de los movimientos se extraen de diversas fuentes y técnicas, de forma que interactivamente solventen sus correspondientes limitaciones. Estos datos se extraen de una documentación previa, tanto en prensa como bibliografía específica, donde se presentan trabajos sobre DInSAR, fotogrametría aérea y LIDAR, y TLS. Además, se realiza de forma específica un análisis dendrogeomorfológico de árboles en movimientos de ladera y se revisa la ortofotografía aérea histórica de la zona de estudio. Posteriormente, con los datos de actividad, se realiza un análisis de los factores desencadenantes, que refleja que los movimientos de ladera están relacionados con episodios de precipitaciones intensas y prolongadas, y no tanto con la actividad sísmica del área. Por último, de forma indirecta, se estima la peligrosidad de la zona de estudio a los movimientos de ladera, asociando los resultados obtenidos de actividad con los factores desencadenantes; esto es, con periodos de precipitaciones intensas. Así, se establece un periodo de retorno que se extrapola a toda el área, con la asunción de que los grandes deslizamientos se generan o reactivan, conjuntamente con movimientos superficiales, tras periodos lluviosos intensos y prolongados, y que las lluvias torrenciales generan movimientos de ladera superficiales tipo flujo y desprendimientos. Los resultados obtenidos indican que la frecuencia con la que se generan los movimientos es de 5 años para los flujos superficiales y desprendimientos (F=0,2), y de 18 años para los deslizamientos y movimientos complejos (F=0,06). La zona, en términos generales, presenta determinados sectores con susceptibilidad moderada a muy alta, sin embargo la peligrosidad a los movimientos de ladera es de moderada a muy baja. En términos de probabilidad temporal, los flujos y desprendimientos son los movimientos con mayor peligrosidad

Dialectics and difference: against Harvey's dialectical post-Marxism

David Harvey`s recent book, Justice, nature and the geography of difference (JNGD), engages with a central philosophical debate that continues to dominate human geography: the tension between the radical Marxist project of recent decades and the apparently disempowering relativism and `play of difference' of postmodern thought. In this book, Harvey continues to argue for a revised `post-Marxist' approach in human geography which remains based on Hegelian-Marxian principles of dialectical thought. This article develops a critique of that stance, drawing on the work of Jacques Derrida, Gilles Deleuze and Felix Guattari. I argue that dialectical thinking, as well as Harvey's version of `post-Marxism', has been undermined by the wide-ranging `post-' critique. I suggest that Harvey has failed to appreciate the full force of this critique and the implications it has for `post-Marxist' ontology and epistemology. I argue that `post-Marxism', along with much contemporary human geography, is constrained by an inflexible ontology which excessively prioritizes space in the theory produced, and which implements inflexible concepts. Instead, using the insights of several `post-' writers, I contend there is a need to develop an ontology of `context' leading to the production of `contextual theories'. Such theories utilize flexible concepts in a multilayered understanding of ontology and epistemology. I compare how an approach which produces a `contextual theory' might lead to more politically empowering theory than `post-Marxism' with reference to one of Harvey's case studies in JNGD

Visual methodologies, sand and psychoanalysis: employing creative participatory techniques to explore the educational experiences of mature students and children in care

Social science research has witnessed an increasing move towards visual methods of data production. However, some visual techniques remain pariah sites because of their association with psychoanalysis; and a reluctance to engage with psychoanalytically informed approaches outside of therapy based settings. This paper introduces the method of ‘sandboxing’, which was developed from the psychoanalytical approach of the ‘world technique’. ‘Sandboxing’ provides an opportunity for participants to create three-dimensional scenes in sand-trays, employing miniature figures and everyday objects. Data is presented from two studies conducted in Wales, UK. The first, exploring mature students’ accounts of higher education, and the second, exploring the educational experiences of children and young people in public care. The paper argues that psychoanalytical work can be adapted to enable a distinctive, valuable and ethical tool of qualitative inquiry; and illustrates how ‘sandboxing’ engendered opportunities to fight familiarity, enabled participatory frameworks, and contributed to informed policy and practice

Playing in the dark with online games for girls

Pregnant Rapunzel Emergency is part of a series of online free games aimed at young girls (forhergames.com or babygirlgames.com), where dozens of characters from fairy tales, children’s toys and media feature in recovery settings, such as ‘Barbie flu’. The range of games available to choose from includes not only dressing, varnishing nails or tidying messy rooms, but also rather more troubling options such as extreme makeovers, losing weight, or a plethora of baby showers, cravings, hospital pregnancy checks, births (including caesarean), postnatal ironing, washing and baby care. Taking the online game Pregnant Rapunzel Emergency as an exemplar of a current digital trend, the authors explore the workings of ‘dark digital play’ from a number of perspectives – one by each named author. The game selected has (what may appear to adults) several disturbing features in that the player is invited to treat wounds of the kind of harm that might usually be associated with domestic violence towards women

The elephant in the room: critical management studies conferences as a site of body pedagogics

This article explores conferences as an inter-corporeal space wherein body pedagogics are enacted, enabling the acquisition of techniques, skills and dispositions that allow newcomers to demonstrate their proficiency as members of a culture. The bodies of conference participants constitute the surface onto which culture is inscribed, these normalizing practices enabling academic power relations to be constructed and identities internalized. An autoethnographic analysis of critical management studies (CMS) conferences forms the basis for identification of the bodily dispositions of control and endurance which characterize the proficient CMS academic. The article considers the potential silencing effects associated with these practices that generate a between-men culture that excludes difference and reinforces patriarchal values. It concludes by reviewing the implications of body pedagogics for understanding how other organizational cultures are constructed

Living in several languages: Language, gender and identities

Living in several languages encompasses experiencing and constructing oneself differently in each language. The research study on which this article is based takes an intersectional approach to explore insider accounts of the place of language speaking in individuals’ constructions of self, family relationships and the wider context. Twenty-four research interviews and five published autobiographies were analysed using grounded theory, narrative and discursive analysis. A major finding was that learning a new language inducted individuals into somewhat ‘stereotyped’ gendered discourses and power relations within the new language, while also enabling them to view themselves differently in the context of their first language. This embodied process could be challenging and often required reflection and discursive work to negotiate the dissimilarities, discontinuities and contradictions between languages and cultures. However, the participants generally claimed that their linguistic multiplicity generated creativity. Women and men used their language differences differently to ‘perform their gender’. This was particularly evident in language use within families, which involved gendered differences in the choice of language for parenting – despite the fact that both men and women experience their first languages as conveying intimacy in their relationships with their children. The article argues that the notion of ‘mother tongue’ (rather than ‘first language’) is unhelpful in this process as well as in considering the implications of living in several languages for systemic therapy
