A classical picture of subnanometer junctions: an atomistic Drude approach to nanoplasmonics

The description of optical properties of subnanometer junctions is particularly challenging. Purely classical approaches fail, because the quantum nature of electrons needs to be considered. Here we report on a novel classical fully atomistic approach, {\omega}FQ, based on the Drude model for conduction in metals, classical electrostatics and quantum tunneling. We show that {\omega}FQ is able to reproduce the plasmonic behavior of complex metal subnanometer junctions with quantitative fidelity to full ab initio calculations. Besides the practical potentialities of our approach for large scale nanoplasmonic simulations, we show that a classical approach, in which the atomistic discretization of matter is properly accounted for, can accurately describe the nanoplasmonics phenomena dominated by quantum effects.Comment: This article is licensed under a Creative Commons Attribution 3.0 Unported Licenc

Evaluating the efficacy of psychodynamic treatment on a single case of autism. A qualitative research.

Autism spectrum disorder refers to a group of diseases determined by multiple conditions and primarily defined on the basis of behavioral patterns. The literature and guidelines provide indications regarding adequate treatments, underlying how psychologically and behaviorally structured interventions, should be considered the best programs. Anyway, there is still a scarcity of studies evidencing the effectiveness of therapeutic and developmental approaches situated in a psychodynamic framework and researches aimed to evaluate the quality of psychodynamic interventions on autism are rare. The present study illustrate a qualitative research on the single-case intervention with an autistic adolescent, admitted to the Educational - Rehabilitation Centre Antenna 112. The Centre bases its intervention on a specific psychodynamic approach, Lacanian Psychoanalysis, named Pratique \ue0 Plusieurs. The efficacy of the psychodynamic intervention is evaluated by monitoring the therapeutic process with the adolescent from his admission. The evaluation took place in three different stages of the intervention: at the beginning of the treatment, after 6 months and after 12 months. In particular, the level of adaptive behaviors (Vineland Adaptive Behavior Scale), Social Communication (Social Communication Questionnaire), and the seriousness of behavioral patterns, specific for the autism disorders (Childhood Autism Rating Scale) have been assessed. Results highlight that the psychodynamic setting of the Centre and the therapeutic intervention, which takes place in it, foster an improvement of adaptive behavior, such as life skills and socialization. Limitations of the present study and clinical implications regarding residential psychodynamic treatments in cases of autism disorders are discussed

Motor skill delays in pre-school children with leukemia one year after treatment: Hematopoietic stem cell transplantation therapy as an important risk factor

CNS-directed therapies for the treatment of leukemia can adversely affect the acquisition of new skills, such as reading/writing and math. Two years after the end of treatments, children show gross and fine motor skill delays that may persist even when patients are considered healed. The goal of the present study was to assess motor skills difficulties in pre-school children with leukemia one year after treatment. Particular attention has been paid to those patients who had undergone Hematopoietic Stem Cell Transplantation (HSCT) and to the relationship between motor delays and age bands. Participants were 60 children (median age of 5; inter quartile range: 3.07-5.76), including 31 females and 29 males, 91.7% of them were affected by acute lymphoblastic leukemia (ALL), and 8.3% by acute myeloid leukemia (AML). Five children had undergone HCST. Parents were interviewed by Vineland Adaptive Behavior Scales (VABS) on children\u2019s motor skills and filled in the Italian Temperament Questionnaire (QUIT). VABS\u2019s total scores were converted into equivalent mental age scores (EMA). A score difference of at least three months between current age and equivalent mental age was considered a developmental delay. Non-parametric analyses were run to understand if HSCT treatment and a specific age band influence children\u2019s motor skills. Significant delays were found in global motor skills (56.7%) as well as in fine and gross motor domains. Mann Whitney U tests showed that children with HSCT were reported to have lower gross motor mean ranks (U = 62; p=0.004; Mean rank =15.40) than peers without HSCT (Mean rank = 31.87) and lower mean rank values on motor temperament scale (U = 9; p = 0.003; HSCT Mean rank = 4.75 versus no HSCT Mean rank = 27.81). Kruskal Wallis\u2019 tests identified the high risk treatment showing that HSCT experience negatively impacted the motor skills and temperamental motor activity of pre-school children one year after the diagnosis of leukemia

The heritage of Brexit: Roles of the past in the construction of political identities through social media

This article assesses the role of the pre-modern past in the construction of political identities relating to the UK’s membership in the European Union, by examining how materials and ideas from Iron Age to Early Medieval Britain and Europe were leveraged by those who discussed the topic of Brexit in over 1.4 million messages published in dedicated Facebook pages. Through a combination of data-intensive and qualitative investigations of textual data, we identify the ‘heritages’ invoked in support of pro- or anti-Brexit sentiments. We show how these heritages are centred around myths of origins, resistance and collapse that incorporate tensions and binary divisions. We highlight the strong influence of past expert practices in shaping such deeply entrenched dualistic thinking and reflect over the longue durée agency of heritage expertise. This is the first systematic study of public perceptions and experience of the past in contemporary society undertaken through digital heritage research fuelled by big data. The article is thus foundational, contributing significantly to theory in cultural heritage studies. It is also the first published work to analyse the role of heritage in the construction of political identities in relation to Brexit, via extensive social research

Multicriteria Evaluation of Urban Regeneration Processes: An Application of PROMETHEE Method in Northern Italy

The paper illustrates the development of an evaluation model for supporting the decision-making process related to an urban regeneration intervention. In particular, the study proposes an original multi-methodological approach, which combines SWOT Analysis, Stakeholders Analysis and PROMETHEE method for the evaluation of alternative renewal strategies of an urban area in Northern Italy. The article also describes the work carried out within an experts' panel that has been organized for validating the structuring of the decision problem and for evaluating the criteria of the model

Primary Hyperparathyroidism in Older People: Surgical Treatment with Minimally Invasive Approaches and Outcome

Introduction. Elderly patients with primary hyperparathyroidism (pHPT) are often not referred to surgery because of their associated comorbidities that may increase surgical risk. The aim of the study was to review indications and results of minimally invasive approach parathyroidectomy in elderly patients to evaluate its impact on outcome. Materials and Methods. All patients of 70 years of age or older undergoing minimally approach parathyroidectomy at our Department from May 2005 to May 2011 were reviewed. Data collected included patients demographic information, biochemical pathology, time elapsed from pHPT diagnosis to surgical intervention, operative findings, complications, and results of postoperative biochemical studies. Results and Discussion. 37 patients were analysed. The average length of stay was 2.8 days. 11 patients were discharged within 24 hours after their operation. Morbidity included 6 transient symptomatic postoperative hypocalcemias while one patient developed a transient laryngeal nerve palsy. Time elapsed from pHPT diagnosis to first surgical visit evidences that the elderly patients were referred after their disease had progressed. Conclusions. Our data show that minimally invasive approach to parathyroid surgery seems to be safe and curative also in elderly patients with few associated risks because of combination of modern preoperative imaging, advances in surgical technique, and advances in anesthesia care

Authentic omnichannel: providing consumers with a seamless brand experience through authenticity

Omnichannel represents a customer-oriented distribution paradigm through which retailers can deliver a seamless customer experience and create an authentic brand narrative that is communicated to customers across diverse touchpoints. Despite the increasing relevance of the omnichannel approach, research on how omnichannel can affect the customer experience remains scant. This research consists of a qualitative study and three experimental studies. Drawing from signaling theory, we contend that the signal congruency established by omnichannel — where all the channels are aligned and convey a consistent message to customers — can enhance consumers’ purchase intention and perceptions of brand authenticity. We further investigate the role of brand authenticity as a mediator of the relationship between multichannel customer experience (seamless vs. non-seamless) and purchase intention, as well as of brand untrustworthiness as a moderator of the relationship between multichannel customer experience and brand authenticity. The results show that a seamless multichannel customer experience has a significant main effect on purchase intention and that participants in the seamless multichannel customer experience condition perceive the brand as more authentic than those in the non-seamless multichannel customer experience condition. Both the mediation and moderation hypotheses are supported. These findings enhance the literature on signaling theory and omnichannel. They also provide insightful implications for retailers in terms of managing the omnichannel customer experience. Overall, this study integrates the research areas of brand authenticity and omnichannel and provides valuable insights by indicating how seamlessness can boost consumers’ perception of brand authenticity. Furthermore, the study advances our knowledge by investigating the impact of brand authenticity as both a result of the omnichannel customer experience and a predictor of purchase intention
