Bilateral semidirect product decompositions of transformation monoids

In this paper we consider the monoid OR(n) of all full transformations on a chain with n elements that preserve or reverse the orientation, as well as its submonoids OD(n) of all order-preserving or order-reversing elements, OP(n) of all orientation-preserving elements and O(n) of all order-preserving elements. By making use of some well known presentations, we show that each of these four monoids is a quotient of a bilateral semidirectproduct of two of its remarkable submonoids.

Joining the online video conversation? Discourse and practices of European political institutions and politicians on YouTube

To mimic the online practices of citizens has been declared an imperative to improve communication and extend participation. This paper seeks to contribute to the understanding of how European discourses praising online video as a communication tool have been translated into actual practices by politicians, governments and organisations. By contrasting official documents with YouTube activity, it is argued that new opportunities for European political communication are far from being fully embraced, much akin to the early years of websites. The main choice has been to use YouTube channels fundamentally for distribution and archiving, thus neglecting its social media features. The disabling of comments by many heads of state and prime ministers - and, in 2010, the European Commission - indicates such an attitude. The few attempts made to foster citizen engagement, in particular during elections, have had limited success, given low participation numbers and lack of argument exchange.

Effectiveness of online corporate collaborative teams

With this article we intend to contribute to the understanding of what can make Online Collaborative Teams (OCT) effective. This is done by identifying what can be considered best practices for individual team members, for leaders of OCT, and for the organizations that the teams are a part of. Best practices in these categories were identified from the existing literature related to online teams and collaborative work literature.

MDAI: Model based Design in Automobile Industry

It is proposed a new approach based on a methodology, assisted by a tool, to create new products in the automobile industry based on previous defined processes and experiences inspired on a set of best practices or principles: it is based on high-level models or specifications; it is component-based architecture centric; it is based on generative programming techniques. This approach follows in essence the MDA (Model Driven Architecture) philosophy with some specific characteristics. We propose a repository that keeps related information, such as models, applications, design information, generated artifacts and even information concerning the development process itself (e.g., generation steps, tests and integration milestones). Generically, this methodology receives the users' requirements to a new product (e.g., functional, non-functional, product specification) as its main inputs and produces a set of artifacts (e.g., design parts, process validation output) as its main output, that will be integrated in the engineer design tool (e.g. CAD system) facilitating the work.

Developmental and evolutionary assumptions in a study about the impact of premature birth and low income on mother���infant interaction

In order to study the impact of premature birth and low income on mother���infant interaction, four Portuguese samples were gathered: full-term, middle-class (n=99); premature, middle-class (n=63); full-term, low income (n=22); and premature, low income (n=21). Infants were filmed in a free play situation with their mothers, and the results were scored using the CARE Index. By means of multinomial regression analysis, social economic status (SES) was found to be the best predictor of maternal sensitivity and infant cooperative behavior within a set of medical and social factors. Contrary to the expectations of the cumulative risk perspective, two factors of risk (premature birth together with low SES) were as negative for mother���infant interaction as low SES solely. In this study, as previous studies have shown, maternal sensitivity and infant cooperative behavior were highly correlated, as was maternal control with infant compliance. Our results further indicate that, when maternal lack of responsiveness is high, the infant displays passive behavior, whereas when the maternal lack of responsiveness is medium, the infant displays difficult behavior. Indeed, our findings suggest that, in these cases, the link between types of maternal and infant interactive behavior is more dependent on the degree of maternal lack of responsiveness than it is on birth status or SES. The results will be discussed under a developmental and evolutionary reasoning

Representa����es dos t��cnicos de interven����o precoce sobre as fam��lias e pr��ticas de IP em contexto rural e urbano

O presente estudo visou caraterizar as representa����es que t��cnicos de interven����o precoce t��m sobre fam��lias que vivem em meio rural e em meio urbano que recebem apoio das equipas. Foram realizadas entrevistas semi-diretivas, os participantes e entrevistados foram dez docentes com interven����o educativa nas equipas, cinco em apoio direto a fam��lias de meio rural e cinco a realizar interven����es com fam��lias de meio urbano. Deste estudo resultaram v��rios dados qualitativos que depois de analisados e discutidos, levaram a diversas conclus��es que vem dar respostas ��s quest��es e problem��tica iniciais. As fam��lias inseridas nestes contextos t��m caracter��sticas que as diferenciam; habilita����es, recursos, necessidades e comportamentos em comunidade. Tem aspetos culturais que influenciam as suas atitudes, participa����o e autonomia e s��o ou n��o decisivas no desenvolvimento da crian��a. Em contexto rural as fam��lias apresentam um maior n��mero de necessidades comparativamente ��s fam��lias de meio urbano. As maiores necessidades das fam��lias em contexto rural situam-se nas quest��es financeiras, de forma����o e apoio t��cnico e especializado. As maiores necessidades das fam��lias de contexto urbano situam-se ao n��vel do fraco apoio familiar e das redes sociais. As necessidades comuns situam-se nas necessidades de informa����o e promo����o da autonomia e compet��ncias parentais. As visitas e interven����es domiciliares podem permitir melhorar a identifica����o das necessidades e recursos das fam��lias e compreender melhor os crit��rios de refer��ncia de algumas crian��as. As oportunidades de aprendizagem s��o maiores nestes encontros em domic��lio, est��o presentes em muitos casos, elementos da fam��lia alargada, que muitas vezes tem um papel fundamental na educa����o e estimula����o destas crian��as. Os docentes de IP em interven����o em contexto urbano, comparativamente com os docentes inseridos em contexto rural, apoiam fam��lias que na generalidade abrangem ��reas profissionais mais vantajosas financeiramente. Estas fam��lias ter��o �� partida melhores condi����es para aceder a mais recursos e apoios. Nos dois contextos existe uma necessidade comum, falta de informa����o e alguma autonomia e compet��ncias parentais em rela����o ao crescimento das crian��as. A realiza����o de iii encontros de pais ou cria����o de grupos de pais que tenham por base a partilha de experiencias e informa����o, est��o planeadas mas n��o s��o uma realidade nestas equipas. Nas pr��ticas de qualidade, o profissional deve atuar nos contextos naturais como, a fam��lia, ou a comunidade, mas pode incluir tamb��m rotinas, brincadeiras, festas etc. cen��rios que facilitem o dia-a-dia. As fam��lias t��m contextos e rotinas pr��prias que os profissionais devem identificar, os dados que recolhemos indicam essa necessidade de proceder a avalia����o mais atenta das necessidades das fam��lias. As pr��ticas recomendadas e o enquadramento legislativo s��o tidos em conta pelos docentes e profissionais das equipas, os recursos documentais s��o na sua maioria comuns, a todas as equipas participantes, seguindo as orienta����es e documentos/minutas facultadas pela comiss��o coordenadora do SNIPI (Sistema Nacional de Interven����o Precoce na Inf��ncia) Apesar das recomenda����es te��ricas para pr��ticas de qualidade centradas na fam��lia, verificamos que estas fazem parte das preocupa����es destes docentes, mas nem sempre s��o implementadas. A problem��tica da crian��a parece ser ainda o ponto mais importante dos programas e planos de interven����o e mesmo o crit��rio decisivo para delinear a dura����o e frequ��ncia das interven����es, seja em contexto urbano ou rural. - ABSTRACT This study aimed to characterize the families of rural and urban areas that receive support from Early Intervention Teams. It has been proposed yet whether professionals IP suit their practices to the characteristics of these families and communities integrated in different cultural contexts. Interviews were conducted semidirective, participants were ten respondents and teachers with educational intervention teams, five in direct support to families in rural areas and five interventions with families in urban areas. This study resulted in a number of qualitative data that then analyzed and discussed, led to several conclusions that comes to answer the questions and problems early. The families included in these contexts have characteristics that differentiate them; qualifications, resources, needs and behaviors in the community. Has cultural aspects that influence their attitudes, participation and autonomy and are not decisive in the development of the child. In the rural households have a greater number of needs compared to urban families. The greatest needs of families in rural settings are located in financial matters, training and technical support and expertise. The greatest needs of the urban households are located at the level of weak family support and social networks. Common needs lie in information needs and promoting autonomy and parenting skills. The home visits and interventions may allow improved identification of needs and resources of families and understand the benchmarks of some children. Learning opportunities are greater in these meetings at home, are present in many cases, elements of the extended family, which often plays a key role in education and stimulation of these children. Teachers IP intervention in the urban compared with rural teachers placed in context, support families in general include professional areas more financially advantageous. These families will have better starting conditions for access to more resources and support. In both contexts there is a common need, lack of information and some autonomy and parenting skills in relation to the growth of children. The meetings of parents or creating parent groups that are based on the sharing of information and experiences are planned but are not a reality in these teams. In quality practices, the professional must act in natural contexts like the family or the community, but may also include routines, jokes, and parties��� etc. scenarios that v facilitate the day-to-day. Families have their own contexts and routines that professionals should identify, collect the data indicate that the need for more careful assessment of the needs of families. Best practices and legislative environment are taken into account by teachers and professional teams, the documentary resources are mostly common to all participating teams, following the guidelines and documents / drafts provided by the coordinating committee SNIPI (National Intervention Early Childhood) Despite the theoretical recommendations for quality practices family-centered, we see that these are part of the concerns of teachers, but are not always implemented. The issue of child seems to be still the most important programs and plans and even the decisive criterion for delineating the duration and frequency of interventions whether in urban or rural.

Les��es da subst��ncia branca por resson��ncia magn��tica: uma avalia����o entre as pondera����es DWI e T2 FLAIR

RESUMO: Objetivos ��� Determinar a sensibilidade e especificidade das pondera����es Difus��o (DWI) e T2 Fluid-Attenuated Inversion Recovery (FLAIR) na avalia����o de les��es da subst��ncia branca (SB) e verificar em que medida se complementam, por forma a criar um conjunto de boas pr��ticas na RM cranioencef��lica de rotina. Metodologia ��� Recorrendo-se a uma metodologia quantitativa, efetuou-se uma an��lise retrospetiva da qual foram selecionados 30 pacientes, 10 sem patologia e 20 com patologia (2 com EM, 7 com Leucoencefalopatia, 6 com doen��a microangiop��tica e 5 com patologia da subst��ncia branca indefinida). Obteve-se uma amostra de 60 imagens, nomeadamente: 30 imagens ponderadas em DWI e 30 em T2 FLAIR. Recorrendo ao programa Viewdex��, tr��s observadores avaliaram um conjunto de imagens segundo sete crit��rios: visibilidade, dete����o, homogeneidade, localiza����o, margens e dimens��es da les��o e capacidade de diagn��stico. Com os resultados obtidos recorreu-se ao c��lculo de sensibilidade e especificidade pelas Curvas ROC, bem como �� an��lise estat��stica, nomeadamente, Teste-T, ��ndice de Concord��ncia Kappa e coeficiente de correla����o de Pearson entre as vari��veis em estudo. Resultados ��� Os resultados de sensibilidade e de especificidade obtidos para a pondera����o T2 FLAIR foram superiores (0,915 e 0,038, respetivamente) aos da pondera����o DWI (0,08 e 0,100, respetivamente). N��o se verificaram vari��ncias populacionais significativas. Obteve-se uma elevada correla����o linear entre as vari��veis com um valor r situado entre 0,8 e 0,99. Verificou-se tamb��m uma variabilidade consider��vel entre os observadores. Conclus��es ��� Dados os baixos valores de sensibilidade e especificidade obtidos para a DWI, sugere-se que esta deva ser inclu��da no protocolo de rotina de cr��nio como auxiliar no diagn��stico diferencial com outras patologias.

Towards the detection of deception in interactive multimedia environments

A classical application of biosignal analysis has been the psychophysiological detection of deception, also known as the polygraph test, which is currently a part of standard practices of law enforcement agencies and several other institutions worldwide. Although its validity is far from gathering consensus, the underlying psychophysiological principles are still an interesting add-on for more informal applications. In this paper we present an experimental off-the-person hardware setup, propose a set of feature extraction criteria and provide a comparison of two classification approaches, targeting the detection of deception in the context of a role-playing interactive multimedia environment. Our work is primarily targeted at recreational use in the context of a science exhibition, where the main goal is to present basic concepts related with knowledge discovery, biosignal analysis and psychophysiology in an educational way, using techniques that are simple enough to be understood by children of different ages. Nonetheless, this setting will also allow us to build a significant data corpus, annotated with ground-truth information, and collected with non-intrusive sensors, enabling more advanced research on the topic. Experimental results have shown interesting findings and provided useful guidelines for future work. Pattern Recognition
