Association between socioeconomic factors and origin of hospital referrals among patients with oral cancer.
2022
The Brazilian Unified Health System (SUS) is responsible for offering free assistance to more than 100 million Brazilians, including treatment of oral cancer lesions. Considering that the Brazilian public system aids the most vulnerable population, this study analyzed whether the origin of hospital referrals of patients with oral cancer is associated with socioeconomic factors. A cross-sectional study was carried out from cancer hospital records of the National Cancer Institute (RHC-INCA), considering the primary locations (C00 to C06) diagnosed between 2016 and 2019. Data on gender, skin color (white and non-white), education (no schooling, incomplete or complete elementary education; high…
Feedback and Communication in Active Hydrogel Spheres with pH Fronts: Facile Approaches to Grow Soft Hydrogel Structures
2021
Abstract Compartmentalized reaction networks regulating signal processing, communication and pattern formation are central to living systems. Towards achieving life‐like materials, we compartmentalized urea‐urease and more complex urea‐urease/ester‐esterase pH‐feedback reaction networks into hydrogel spheres and investigate how fuel‐driven pH fronts can be sent out from these spheres and regulated by internal reaction networks. Membrane characteristics are installed by covering urease spheres with responsive hydrogel shells. We then encapsulate the two networks (urea‐urease and ester‐esterase) separately into different hydrogel spheres to devise communication, pattern formation and attracti…
Net currents obtained from zero-average potentials in single amphoteric nanopores
2013
We have studied experimentally and theoretically the rectifying properties of a single asymmetric nanopore functionalized with amphoteric lysine groups and characterized the net current obtained with zero-average time dependent potentials. The pH-controlled rectification phenomena may be relevant to bio-electrochemistry, pH sensing and regulation, and energy conversion. (C) 2013 Elsevier B.V. All rights reserved.
Sfide postmoderne a una paideia umanistica
2016
In questo saggio sono esposte le tesi caratterizzanti del pensiero debole, inteso come Weltanschauung spontanea diffusa tra le nuove generazioni e interpretato come sfida radicale all’idea centrale di una paideia di tradizione umanistica. Sono poi presi in esame alcuni rilievi critici emersi dal cosiddetto “realismo critico”, relativi al misconoscimento della realtà e delle differenze. L’autore le discute e le approfondisce nella prospettiva di una ontologia della persona, essenzialmente definita dalle categorie di avvenimento formativo e di riconoscimento, della realtà, dei volti, delle differenze. In this essay are exposed the main thesis of the weak thought, meant as spontaneous Weltansc…
Location-Awareness for Failure Management in Cellular Networks: An Integrated Approach
2021
Recent years have seen the proliferation of different techniques for outdoor and, especially, indoor positioning. Still being a field in development, localization is expected to be fully pervasive in the next few years. Although the development of such techniques is driven by the commercialization of location-based services (e.g., navigation), its application to support cellular management is considered to be a key approach for improving its resilience and performance. When different approaches have been defined for integrating location information into the failure management activities, they commonly ignore the increase in the dimensionality of the data as well as their integration into th…
Interneta pakalpojumu sniedzēja iekšējā informāciju sistēma klientu, pakalpojumu un rēķinu uzskaitei
2022
Kvalifikācijas darba mērķis ir izstrādāt interneta paklpojumu sniedzēja SIA “Dhanvantari Telecom” iekšējo informācijas sistēmu atbilstoši klienta prasībām. Sistēma ir paredzēta, lai uzglabātu datus par klientiem, tiem sniegtajiem pakalpojumiem, kā arī izrakstītajiem rēķiniem. Tāpat sistēma ģenerē rēķinus, balstoties uz izmaksām, kas radušās nodrošinot klientiem sniegtos pakalpojumus, un šos rēķinus izsūta attiecīgajiem klientiem reizi mēnesi. Šajā dokumentā tiek aprakstītas sistēmas programmatūras projektējums, funkcionalitāte, prasības, projekta pārvaldība un daļa no programmatūras pirmkoda.
Value Co-Destruction: A Conceptual Review and Future Research Agenda
2023
The service-dominant (S-D) logic lens for understanding value co-creation and customers’ interactive roles in the service exchange has emerged as a focal theme of interest among service academics and practitioners. While recent investigations have also focused on the process of value co-destruction—that is, how potential negative outcomes occur—the concept and its distinction from value co-creation remain unclear. This conceptual review synthesizes the concept of value co-destruction and proposes a framework consisting of two interrelated dimensions—actor–actor interaction and individual actor —and their components at three temporal points of the service encounter. We distinguish value co-…
How does information technology-based service degradation influence consumers’ use of services? : An information technology-based service degradation…
2020
Information technology is crucial for modern services. Service delivery may include a complex mix of information technology and telecommunication providers, global networks and customers’ information technology devices. This research focuses on service failures that are caused by information technology problems, which we conceptualize as information technology-based service degradation (ITSD). When information technology-based service degradation occurs in a modern service, the information technology problem may originate from the service provider, another partner or any information technology equipment involved. But the customer may not be able to pinpoint the source of the problem immedia…
Proto-Indo-European verbal suppletion and emerging paradigms
2008
The existence of suppletion in a Proto-Indo-European language is still a question of debate (García Ramón 2002). While the evidence for such a phenomenon has been widely recognized within the verbal system of most Indo-European languages, some scholars describe it as a recent monoglot development which characterizes the history of each single language without involving a previous common stage. According to Strunk (1977), the hypothesis of a PIE suppletive paradigm based on the alternation of verbal roots such as *es- and *bhu- “be”, or *ei-/i- and *gwa-/ gwem - “go”, must be ruled out because it violates the so-called criterium-b, i.e. complementary distribution of the forms involved in a s…
Usage des organisateurs anti-entropique dans les documents électroniques : approche expérimentale des fenêtres ponctuelles
1999
International audience; Les documents électroniques permettent de nombreuses manières d'organiser, de présenter et d'accéder à l'information. Une utilisation pertinente de ces options par les auteurs requiert une bonne connaissance des effets que ces choix ont sur la représentation cognitive et les traitements faits par l'utilisateur. Cette approche des documents électroniques, sur la base du concept de représentation mentale, fournit un cadre d'analyse des structures et signaux propres à ce type d'écriture. Parmi ces signaux que nous appelons « organisateurs para-linguistiques » pour les distinguer de leurs équivalents purement textuels, un ensemble est destiné à réduire l'entropie due à l…
