Qualidade do processamento sensorial e vinculação infantil

Estudou-se a relação entre a segurança da vinculação e a qualidade do processamento sensorial na primeira infância. Para o efeito, seleccionou-se uma amostra normativa de 40 díades mãe-bebé, com crianças entre os 11 e os 18 meses. Avaliou-se a qualidade da vinculação, observando a díade no procedimento Situação Estranha. Classificaram-se 17 (42,5%) das crianças no grupo de vinculação segura, sendo que as restantes 23 (57,5%) revelaram uma vinculação não segura. A qualidade do processamento sensorial avaliou-se através do Teste de Funções Sensoriais. Constatou-se que a segurança da vinculação infantil associava-se a um score agregando quatro factores ambientais (nível sócio-económico dos pais; existência de internamentos hospitalares; coeficiente de número de irmãos; local onde a criança passa o dia). O Teste de Funções Sensoriais não apresentou valor prognóstico relativamente ao tipo de vinculação. Porém, a boa qualidade no processamento da informação sensorial parece constituir um factor de resiliência no desenvolvimento da vinculação.

Improving Remote Voting Security with Code Voting

One of the major problems that prevents the spread of elections with the possibility of remote voting over electronic networks, also called Internet Voting, is the use of unreliable client platforms, such as the voter's computer and the Internet infrastructure connecting it to the election server. A computer connected to the Internet is exposed to viruses, worms, Trojans, spyware, malware and other threats that can compromise the election's integrity. For instance, it is possible to write a virus that changes the voter's vote to a predetermined vote on election's day. Another possible attack is the creation of a fake election web site where the voter uses a malicious vote program on the web site that manipulates the voter's vote (phishing/pharming attack). Such attacks may not disturb the election protocol, therefore can remain undetected in the eyes of the election auditors. We propose the use of Code Voting to overcome insecurity of the client platform. Code Voting consists in creating a secure communication channel to communicate the voter's vote between the voter and a trusted component attached to the voter's computer. Consequently, no one controlling the voter's computer can change the his/her's vote. The trusted component can then process the vote according to a cryptographic voting protocol to enable cryptographic verification at the server's side.

More than maternal sensitivity shapes attachment : infant coping and temperament

The aim of this longitudinal studywas to investigate the effect of a set of factors from multiple levels of influence: infant temperament, infant regulatory behavior, and maternal sensitivity on infant’s attachment. Our sample consisted of 48 infants born prematurely and their mothers. At 1 and 3 months of age, mothers described their infants’behavior using the Escala de Temperamento do Beb´e. At 3 months of age, infants’ capacity to regulate stress was evaluated during Tronick’s Face-to-Face Still-Face (FFSF) paradigm. At 9 months of age, mothers’ sensitivity was evaluated during free play using the CARE-Index. At 12 months of age, infants’ attachment security was assessed during Ainsworth’s Strange Situation. A total of 16 infants were classified as securely attached, 17 as insecure-avoidant, and 15 as insecure-resistant. Mothers of securely attached infantswere more likely than mothers of insecure infants to describe their infants as less difficult and to be more sensitive to their infants in free play. In turn, secure infants exhibited more positive responses during the Still-Face. Infants classified as insecureavoidant were more likely to self-comfort during the Still-Face and had mothers who were more controlling during free play. Insecure-resistant exhibited higher levels of negative arousal during the Still-Face and had mothers who were more unresponsive in free play. These findings show that attachment quality is influenced bymultiple factors, including infant temperament, coping behavior, and maternal sensitivity.

Cuidados de saúde primários: as regras do jogo

Enquadramento – A reforma dos Cuidados de Saúde Primários (CSP) é um facto irreversível. Uma “onda” de reforma percorre igualmente grande parte dos países ocidentais exigindo uma reflexão sobre o processo. Objetivo – Descrever a reforma em curso nos CSP e identificar os potenciais factores de sucesso e insucesso dos serviços públicos de cuidados de saúde primários. Metodologia – Análise crítica da literatura. Resultados e conclusões – A eficiência, eficácia e equidade de acesso aos cuidados de saúde são insuficientes. Mudanças organizacionais estão a ser operadas alterando as relações e a cooperação inter‑profissional e inter‑organizacional. É evidente a tensão que existe entre as partes envolvidas. Novas formas organizacionais estão a ser criadas para garantir a viabilidade das reformas e equilíbrio dos sistemas. O novo modelo organizacional, se pretender garantir a sustentabilidade e a viabilidade dos cuidados primários, deverá assentar num equilíbrio de gestão de recursos e numa estratégia de saúde para todos que não significa saúde para tudo. ABSTRACT: Background – Primary Health Care (PHC) reform is a fact in several countries and is happening also in Portugal demanding a reflection on the process. Aim – To describe the PHC reform and to identify the factors of success or potential failure in PHC public services. Methods – Critical appraisal of the literature. Results and Conclusions – The efficiency, efficacy and access to health care are insufficient. Organizational changes are taking place altering inter‑professional and inter‑organizational cooperation and relationship. Tension among the parts involved is evident. New organizational models are being created to secure the sustainability of the reforms and the systems. The new models should provide a balanced management of the available resources, in a strategy of health for all that doesn’t mean health for everything.

Statistical analysis of quality control measurements in IMRT for head and neck and prostate cancer

Intensity Modulated Radiotherapy (IMRT) is a technique introduced to shape more precisely the dose distributions to the tumour, providing a higher dose escalation in the volume to irradiate and simultaneously decreasing the dose in the organs at risk which consequently reduces the treatment toxicity. This technique is widely used in prostate and head and neck (H&N) tumours. Given the complexity and the use of high doses in this technique it’s necessary to ensure as a safe and secure administration of the treatment, through the use of quality control programmes for IMRT. The purpose of this study was to evaluate statistically the quality control measurements that are made for the IMRT plans in prostate and H&N patients, before the beginning of the treatment, analysing their variations, the percentage of rejected and repeated measurements, the average, standard deviations and the proportion relations.

Physical layer aware network architecture for the future internet

In this article, physical layer awareness in access, core, and metro networks is addressed, and a Physical Layer Aware Network Architecture Framework for the Future Internet is presented and discussed, as proposed within the framework of the European ICT Project 4WARD. Current limitations and shortcomings of the Internet architecture are driving research trends at a global scale toward a novel, secure, and flexible architecture. This Future Internet architecture must allow for the co-existence and cooperation of multiple networks on common platforms, through the virtualization of network resources. Possible solutions embrace a full range of technologies, from fiber backbones to wireless access networks. The virtualization of physical networking resources will enhance the possibility of handling different profiles, while providing the impression of mutual isolation. This abstraction strategy implies the use of well elaborated mechanisms in order to deal with channel impairments and requirements, in both wireless (access) and optical (core) environments.

The effects of parental sensitivity and involvement in caregiving on mother–infant and father–infant attachment in a portuguese sample

In the present longitudinal study, we investigated attachment quality in Portuguese mother–infant and in father–infant dyads, and evaluated whether attachment quality was related to parental sensitivity during parent–infant social interaction or to the amount of time each parent spent with the infant during play and in routine caregiving activities (e.g., feeding, bathing, play). The sample consisted of 82 healthy full-term infants (30 girls, 53 boys, 48 first born), and their mothers and fathers from mostly middle-class households. To assess parental sensitivity, mothers and fathers were independently observed during free play interactions with their infants when infants were 9 and 15 months old. The videotaped interactions were scored by masked coders using the Crittenden’s CARE-Index. When infants were 12 and 18 months old, mother–infant and father–infant dyads were videotaped during an adaptation of Ainsworth’s Strange Situation. Parents also described their level of involvement in infant caregiving activities using a Portuguese version of the McBride and Mills Parent Responsibility Scale. Mothers were rated as being more sensitive than fathers during parent–infant free play at both 9 and 15 months. There also was a higher prevalence of secure attachment in mother–infant versus father–infant dyads at both 12 and 18 months. Attachment security was predicted by the amount of time mothers and fathers were involved in caregiving and play with the infant, and with parents’ behavior during parent–infant free play.
