Constructions, Claims, Resonance, Reflexivity: Language and Market Categorization
2020
doi: 10.1177/2631787720968561 Studies on market categorization exhibit substantial agreement that language plays a central role in articulating and constructing meanings among market participants and crafting consensus to produce a collective of interacting market actors. The purpose of this paper is to take stock of the growing body of research on language and market categories. This review has two aims. We begin by identifying how scholars have applied a variety of language constructs in category research, providing an understanding of the differences between these constructs and elaborating their uses and functions in the studies on market categorization. The second part of the review th…
A sociology of queer implications? Methodological inquietudes and ethical involvements in the study of non-normative sexualities
2018
The article represents an epistemological and methodological enquiry on the use of qualitative research methods, and specifically ethnographical practice, in the study of non-normative sexualities. It will take mainly into account a series of ethnographic observations of an ongoing research project on male sex work in southern Italy.
Mocking fakeness
2022
Abstract Phonetic resources, like dialects and accents, are used in ethnic humour to build up a recognisable character that pokes fun at the stereotypes associated with a particular identity, sometimes with critical and political undertones. In this article, we examine the manipulation of one such resource, aspiration, used in performing and mocking one such clichéd character, called the fake Sámi. This character has a contested history in Finnish tourism and marketing practices, and is embedded in a long-standing debate about who can use emblems of Sámi identity for economic purposes. Adopting a sociophonetic language regard and folk linguistics approaches (Preston 2010; Niedzielski & …
Emisores políticos, mediáticos y ciudadanos en internet: hacia un nuevo marco comunicativo en la jornada de reflexión en España
2015
Resumen La campaña electoral en España está regulada por la ley orgánica de régimen electoral general 5/1985, que no contempla ninguna medida específica para la cibercampaña. Este vacío legal motiva a los emisores a realizar una interpretación de la norma cuando se comunican en internet durante este periodo. Con el fin de explorar si el nuevo tempo y forma de comunicación en internet se corresponde con un nuevo espacio comunicativo, este estudio analiza los mensajes que políticos, periodistas y ciudadanos se intercambiaron en la jornada de reflexión de las últimas elecciones generales españolas (2011) y muestra cómo esta jornada, comprendida hasta la fecha como un día de reflexión silencios…
Comparison of frequency domain measures based on spectral decomposition for spontaneous baroreflex sensitivity assessment after Acute Myocardial Infa…
2021
Abstract The objective of this study is to present a new method to assess in the frequency domain the directed interactions between the spontaneous variability of systolic arterial pressure (SAP) and heart period (HP) from their linear model representation, and to apply it for studying the baroreflex control of arterial pressure in healthy physiological states and after acute myocardial infarction (AMI). The method is based on pole decomposition of the model transfer function and on the following evaluation of causal measures of coupling and gain from the poles associated to low frequency (0.04−0.15 Hz) oscillatory components. It is compared with traditional non-causal approaches for the sp…
Binocular, Accommodative and Oculomotor Alterations In Multiple Sclerosis: A Review
2020
Multiple sclerosis (MS) is an acquired demyelinating and inflammatory neurodegenerative disease affecting the central nervous system (CNS). Clinical and subclinical ocular disturbances occur in almost all patients with MS. The objective of this narrative review was to collect and summarize the available scientific information on oculomotor, accommodative and binocular alterations that have been reported in MS. A systematic search strategy with the following descriptors was carried out: multiple sclerosis, ocular motility disorders, internuclear ophthalmoplegia, nystagmus, vergences, fixation, pupil reflex, accommodation and stereopsis. According to the search, some oculomotor alterations w…
Noninvasive assessment of baroreflex sensitivity in post-MI patients by an open loop parametric model of RR-systolic pressure interactions
2003
Noninvasive evaluation of baroreflex sensitivity is considered an important goal for diagnosis and prognosis in post-MI patients. Methodological approach and physiological measure conditions may be the main causes for the differences found with respect to the standard Phenylephrine test. In this study, three linear parametric models, describing variability and mutual interactions of RR interval and systolic arterial pressure (SAP), were compared in relation to their ability to quantify baroreflex gain, using the Phenylephrine test index (Phe/sub BRS/) as reference. By monovariate autoregressive (AR) model, bivariate AR model and open loop ARXAR model, specific gain indexes (/spl alpha//sub …
Differences in visual information processing style between Idiopathic Generalized Epilepsy with and without photosensitivity.
2021
Purpose: Recently, altered visual cortical processes i.e., lack of habituation to visual evoked potentials (VEP), has been highlighted in both photosensitive epilepsy and in a specific i.e., analytic mode of processing visual inputs. In this study we aimed at evaluating the relationship between photosensitivity (PS) and analytic style of processing visual information, in a sample of 30 patients with Idiopathic Generalized Epilepsy (IGE) and matched healthy controls. Methods: At our Epilepsy unit of the Sapienza University of Rome, we consecutively enrolled 15 patients with IGE with PSand matched them with 15 patients with IGE without PS and 15 Healthy Volunteers. All patients underwent EEG …
Update on the effects of graded motor imagery and mirror therapy on complex regional pain syndrome type 1: A systematic review.
2017
Graded motor imagery (GMI) and mirror therapy (MT) is thought to improve pain in patients with complex regional pain syndrome (CRPS) types 1 and 2. However, the evidence is limited and analysis are not independent between types of CRPS. The purpose of this review was to analyze the effects of GMI and MT on pain in independent groups of patients with CRPS types 1 and 2. Searches for literature published between 1990 and 2016 were conducted in databases. Randomized controlled trials that compared GMI or MT with other treatments for CRPS types 1 and 2 were included. Six articles met the inclusion criteria and were classified from moderate to high quality. The total sample was composed of 171 p…
Local Sleep Slow-Wave Activity Colocalizes With the Ictal Symptomatogenic Zone in a Patient With Reflex Epilepsy
2020
Background: Slow-wave activity (SWA) during non-rapid eye movement (NREM) sleep reflects synaptic potentiation during preceding wakefulness. Epileptic activity may induce increases in state-dependent SWA in human brains, therefore, localization of SWA may prove useful in the presurgical workup of epileptic patients. We analyzed high-density electroencephalography (HDEEG) data across vigilance states from a reflex epilepsy patient with a clearly localizable ictal symptomatogenic zone to provide a proof-of-concept for the testability of this hypothesis. Methods: Overnight HDEEG recordings were obtained in the patient during REM sleep, NREM sleep, wakefulness, and during a right facial motor s…
