Graph Embedding via High Dimensional Model Representation for Hyperspectral Images
2021
Learning the manifold structure of remote sensing images is of paramount relevance for modeling and understanding processes, as well as to encapsulate the high dimensionality in a reduced set of informative features for subsequent classification, regression, or unmixing. Manifold learning methods have shown excellent performance to deal with hyperspectral image (HSI) analysis but, unless specifically designed, they cannot provide an explicit embedding map readily applicable to out-of-sample data. A common assumption to deal with the problem is that the transformation between the high-dimensional input space and the (typically low) latent space is linear. This is a particularly strong assump…
Visualization of Jacques Lacan's Registers of the Psychoanalytic Field, and Discovery of Metaphor and of Metonymy. Analytical Case Study of Edgar All…
2016
We start with a description of Lacan's work that we then take into our analytics methodology. In a first investigation, a Lacan-motivated template of the Poe story is fitted to the data. A segmentation of the storyline is used in order to map out the diachrony. Based on this, it will be shown how synchronous aspects, potentially related to Lacanian registers, can be sought. This demonstrates the effectiveness of an approach based on a model template of the storyline narrative. In a second and more comprehensive investigation, we develop an approach for revealing, that is, uncovering, Lacanian register relationships. Objectives of this work include the wide and general application of our met…
Time Difference of Arrival Estimation from Frequency-Sliding Generalized Cross-Correlations Using Convolutional Neural Networks
2020
The interest in deep learning methods for solving traditional signal processing tasks has been steadily growing in the last years. Time delay estimation (TDE) in adverse scenarios is a challenging problem, where classical approaches based on generalized cross-correlations (GCCs) have been widely used for decades. Recently, the frequency-sliding GCC (FS-GCC) was proposed as a novel technique for TDE based on a sub-band analysis of the cross-power spectrum phase, providing a structured two-dimensional representation of the time delay information contained across different frequency bands. Inspired by deep-learning-based image denoising solutions, we propose in this paper the use of convolutio…
Framing Social Work Discourses of Violence Against Women. Insights From Finland and India
2021
Violence against women (VAW) is a global social problem. In India, its high prevalence is connected to gender inequality, whereas Finland suffers from the so-called Nordic Paradox—that is, the existence of both gender equality and a high prevalence of VAW. This qualitative study employed a critical constructioniist approach and frame analysis to analyze data from interviews with Finnish (n =20) and Mumbai (n =18) social workers. We asked how social workers frame their response to VAW and how ways of framing elucidate institutional practices that facilitate the interventions. Anti-oppressive, juridical, procedural, and collaborational frames revealed institutional practices mirroring how soc…
Landscapes of loss and destruction: : Sámi elders’ childhood memories of the second world war
2019
The so-called Lapland War between Finland and Germany at the end of the Second World War led to a mass-scale destruction of Lapland. Both local Finnish residents and the indigenous Sámi groups lost their homes, and their livelihoods suffered in many ways. The narratives of these deeply traumatic experiences have long been neglected and suppressed in Finland and have been studied only recently by academics and acknowledged in public. In this text, we analyze the interviews with four elders of one Sámi village, Vuotso. We explore their memories, from a child’s perspective, scrutinizing the narration as a multilayered affective process that involves sensual and embodied dimensions of memory. ©…
Embodied graffiti and street art research
2021
Graffiti and street art research (GSAR) has become more acknowledged within the academic discourse; however, it has much to gain from theorising its methodological aspects. As a multidisciplinary field, GSAR has mostly used qualitative research methods, exploring urban space through methods that range from visual recordings to ethnography, emphasising the researchers’ reflexivity. This qualitative approach has, however, paid little attention to the role of embodied practices. In this paper we discuss how embodied methodologies provide multisensory research results where the experienced moments, the participant’s and researcher’s senses, cognition and mobility in urban spaces are connected.…
Le opere esposte da Maria Accascina alla Mostra d’Arte Sacra delle Madonie
2017
Il saggio espone i metodi e gli strumenti di ricerca utilizzati per la ricostruzione del catalogo della pioneristica Mostra D’Arte Sacra delle Madonie curata da Maria Accascina ed allestita nel 1937 presso il Convento dei PP. Riformati di Petralia Sottana, centro delle alte Madonie. Si tratta di più di quattrocento opere, tra gioielli, suppellettili liturgiche, oggetti preziosi di uso profano, coralli, paramenti sacri, tessuti, statue lignee, intagli, maioliche, tappeti, tele e tavole dipinte realizzate dal XI al XIX secolo. Le opere, alcune delle quali perdute, provengono dalle collezioni nobiliari, dall’allora Museo Nazionale di Palermo, ora Galleria Regionale della Sicilia, Palazzo Abate…
Fathers in focus: two discursive analyses on addressing men, work and care
2022
We introduce in this chapter discourse analysis as a methodological tool for studying work-family issues, particularly those of men and fathers in work and care. Work and family involve complex processes and dynamics, where reconciling different interpretations of events are temporally and contextually changing. Current discourses on involved fatherhood raise many questions about men's work and family relationships and the role of care in their life. Here we present two empirical examples using discourse analysis to study work-family issues from a male gender perspective in the Finnish context. Finally, we discuss the (dis)advantages of using discursive analytical perspectives in work-famil…

Ennakoivien toimijoiden diskursiivinen tuottaminen syntyvyyden vähenemistä käsittelevissä kantaaottavissa kirjoituksissa
2022
Syntyvyyden väheneminen on kiivaasti keskusteltu aihe. Vähenemisen syitä on etsitty esimerkiksi työelämän epävarmuudesta, työn ja lastenhoidon yhteensovittamisen hankaluuksista ja lapsiperhe-elämän vähäisestä houkuttelevuudesta pidentyneen nuoruuden kulttuurissa. Tätä sekä mediassa että tutkimuskirjallisuudessa käytyä keskustelua täydennämme tarkastelemalla ennakoinnin teorian ulottuvuuksia Helsingin Sanomissa vuosina 2018–2019 julkaistuissa syntyvyyden vähenemistä koskevissa kantaaottavissa kirjoituksissa. Diskurssianalyyttisiä välineitä käyttäen osoitamme, miten kirjoituksissa tuotetaan yksilöistä ennakoivia toimijoita ja miten ennakoinnista tuotetaan, erityisesti nuorille naisille, norma…
