Long-lasting coma.
2014
n this report, we describe the case of a patient who has remained in a comatose state for more than one year after a traumatic and hypoxic brain injury. This state, which we refer to as long-lasting coma (LLC), may be a disorder of consciousness with significantly different features from those of conventional coma, the vegeta- tive state, or brain death. On the basis of clinical, neu- rophysiological and neuroimaging data, we hypothe- size that a multilevel involvement of the ascending reticular activating system is required in LLC. This description may be useful for the identification of other patients suffering from this severe disorder of con- sciousness, which raises important ethical i…
Neural correlates of intimate picture stimuli in females
2018
Jacob et al. (2011) previously reported on intimate picture stimuli for emotion research in females in Psychiatry Research. Difficulties to engage in intimate relations constitute problems of many mental disorders, and intimacy must be differentiated from pure sex drive. Functional neuroimaging is an important tool to understand the pathophysiology of psychiatric disorders. We now studied cerebral activation in response to intimate stimuli in 35 healthy women. Comparison stimuli were taken from the International Affective Picture System. Neuroimaging revealed increased activation in bilateral occipitotemporal, parietal and anterior cingulate cortices extending to the orbitofrontal area. The…
Time Up for Phishing with Effective Anti-Phishing Research Strategies
2015
Public awareness is a significant factor in the battle against online identity theft (phishing). Advancing public readiness can be a strategic protection mechanism for citizens' vulnerability and privacy. Further, an effective research strategy against phishing is the combination of increased social awareness with software quality and social computing. The latter will decrease phishing victims and will improve information systems quality. First, the authors discuss recent research results on software quality criteria used for the design of anti-phishing technologies. Second, it is argued that the dynamics of social surroundings affect citizens' trust and can compromise social security. Thir…
Self-esteem, Defensive Strategies and Social Intelligence in the Adolescence
2012
Abstract A variety of studies documented that self-esteem is related to protective strategies including self-handicapping and causal attributions in the school domain. In particular, these defensive modalities, both proactive and retroactive, refer to some of the maladaptive strategies employed by an individual, respectively before and after performing difficult and threatening tasks, to protect him or herself and maintain a positive self-esteem. Within the theoretical framework of self-regulation, the maintenance and the protection of competency self-images implies the social intelligence model of personality ( Cantor and Kihlstrom, 1987 ). The social intelligence, which includes self-conc…
Professionals' Views on the Comparatively Low Prevalence of Intimate Partner Violence Against Women in Spain.
2021
The aim of this study was to understand the reasons why Spain has one of the lowest prevalence rates of intimate partner violence against women (IPVAW) in the European Union. Using a qualitative and inductive research approach, a total of five focus groups ( n = 19) and 10 unstructured interviews with key informants were conducted. Three main categories were identified as possible explanations of the relatively low prevalence of IPVAW in Spain: law and policy, social awareness, and cultural patterns. Lessons learned and implications to improve future macrolevel intervention and prevention strategies are discussed.
Machine learning for a combined electroencephalographic anesthesia index to detect awareness under anesthesia
2020
Spontaneous electroencephalogram (EEG) and auditory evoked potentials (AEP) have been suggested to monitor the level of consciousness during anesthesia. As both signals reflect different neuronal pathways, a combination of parameters from both signals may provide broader information about the brain status during anesthesia. Appropriate parameter selection and combination to a single index is crucial to take advantage of this potential. The field of machine learning offers algorithms for both parameter selection and combination. In this study, several established machine learning approaches including a method for the selection of suitable signal parameters and classification algorithms are a…
The rediscovery of nature: the lost innocence of the digital world
2022
L’impatto della nostra impronta ecologica legata al tasso di crescita incontrollato della tecnologia digitale sta portando ad un aggravamento degli squilibri ambientali esistenti. Il digitale e i new media che fino a ieri ci apparivano una terra promessa dell’emancipazione umana, oggi rilevano enormi effetti inquinanti sulla biosfera che devono essere obbligatoriamente evidenziati. Nel contributo si intende sottoporre a indagine le cause della “perduta innocenza” del mondo digitale anche attraverso una ricostruzione analitica sui fenomeni che sino a poco tempo fa venivano percepiti come veicoli immateriali, assolutamente non invasivi per l’ambiente e dalle straordinarie potenzialità di prog…
Valenza umana della cura (care) dei pazienti in SVP e ruolo dei caregivers
2016
[Human value of care and caregivers' role in the management of permanent vegetative state (SVP) patients] As stated by the Royal College of Physicians, «patients who remain in a vegetative or minimally conscious state following profound brain injury present a complex array of clinical and ethical challenges to those who care for them». Patients in clinical condition of Permanent Vegetative State (SVP) are unaware of self and environment, enable of language comprehension or expression; they are able to survive along provided that we are able to ensure primary care, such as eating and hydration. With regard to this existential landmark, caregiver’s role is not only legally related, as guardia…
Understanding Mobile Showrooming Based on a Technology Acceptance and Use Model
2021
Showrooming is an increasingly popular behaviour in the omnichannel era. The purpose of this paper is to understand the consumer intention to showroom through a technology acceptance and use model based on UTAUT2 that includes value consciousness and purchase involvement as drivers of showrooming intention and mobile dependency as a moderator. Data collected via a survey answered by 659 showroomers were analysed using Partial Least Squares (PLS). Results show that value consciousness, purchase involvement, hedonic motivation and social influence explain mobile showrooming intention and mobile dependency moderates the impact of value consciousness on mobile showrooming intention. Our results…
Diagnostic and therapeutic aspects of hemiplegic migraine
2020
Hemiplegic migraine (HM) is a clinically and genetically heterogeneous condition with attacks of headache and motor weakness which may be associated with impaired consciousness, cerebellar ataxia and intellectual disability. Motor symptoms usually last <72 hours and are associated with visual or sensory manifestations, speech impairment or brainstem aura. HM can occur as a sporadic HM or familiar HM with an autosomal dominant mode of inheritance. Mutations in CACNA1A, ATP1A2 and SCN1A encoding proteins involved in ion transport are implicated. The pathophysiology of HM is close to the process of typical migraine with aura, but appearing with a lower threshold and more severity. We review…
