Gestão e trabalhadores do conhecimento em Tecnologias da informação (UML)

RESUMO: O conhecimento existe desde sempre, mesmo num estado latente condicionado algures e apenas à espera de um meio (de uma oportunidade) de se poder manifestar. O conhecimento é duplamente um fenómeno da consciência: porque dela procede num dado momento da sua vida e da sua história e porque só nela termina, aperfeiçoando-a e enriquecendo-a. O conhecimento está assim em constante mudança. À relativamente pouco tempo começou-se a falar de Gestão do Conhecimento e na altura foi muito associada às Tecnologias da Informação, como meio de colectar, processar e armazenar cada vez mais, maiores quantidades de informação. As Tecnologias da Informação têm tido, desde alguns anos para cá, um papel extremamente importante nas organizações, inicialmente foram adoptadas com o propósito de automatizar os processos operacionais das organizações, que suportam as suas actividades quotidianas e nestes últimos tempos as Tecnologias da Informação dentro das organizações têm evoluído rapidamente. Todo o conhecimento, mesmo até o menos relevante de uma determinada área de negócio, é fundamental para apoiar o processo de tomada de decisão. As organizações para atingirem melhores «performances» e conseguirem transcender as metas a que se propuseram inicialmente, tendem a munir-se de mais e melhores Sistemas de Informação, assim como, à utilização de várias metodologias e tecnologias hoje em dia disponíveis. Por conseguinte, nestes últimos anos, muitas organizações têm vindo a demonstrar uma necessidade crucial de integração de toda a sua informação, a qual está dispersa pelos diversos departamentos constituintes. Para que os gestores de topo (mas também para outros funcionários) possam ter disponível em tempo útil, informação pertinente, verdadeira e fiável dos negócios da organização que eles representam, precisam de ter acesso a bons Sistemas de Tecnologias de Informação. Numa acção de poderem agir mais eficazmente e eficientemente nas tomadas de decisão, por terem conseguido tirar por esses meios o máximo de proveito possível da informação, e assim, apresentarem melhores níveis de sucesso organizacionais. Também, os Sistemas de «Business Intelligence» e as Tecnologias da Informação a ele associadas, utilizam os dados existentes nas organizações para disponibilizar informação relevante para as tomadas de decisão. Mas, para poderem alcançar esses níveis tão satisfatórios, as organizações necessitam de recursos humanos, pois como podem elas serem competitivas sem Luís Miguel Borges – Gestão e Trabalhadores do Conhecimento em Tecnologias da Informação (UML) ULHT – ECATI 6 trabalhadores qualificados. Assim, surge a necessidade das organizações em recrutar os chamados hoje em dia “Trabalhadores do Conhecimento”, que são os indivíduos habilitados para interpretar as informações dentro de um domínio específico. Eles detectam problemas e identificam alternativas, com os seus conhecimentos e discernimento, eles trabalham para solucionar esses problemas, ajudando consideravelmente as organizações que representam. E, usando metodologias e tecnologias da Engenharia do Conhecimento como a modelação, criarem e gerirem um histórico de conhecimento, incluindo conhecimento tácito, sobre várias áreas de negócios da organização, que podem estar explícitos em modelos abstractos, que possam ser compreendidos e interpretados facilmente, por outros trabalhadores com níveis de competência equivalentes. ABSTRACT: Knowledge has always existed, even in a latent state conditioning somewhere and just waiting for a half (an opportunity) to be able to manifest. Knowledge is doubly a phenomenon of consciousness: because proceeds itself at one point in its life and its history and because solely itself ends, perfecting it and enriching it. The knowledge is so in constant change. In the relatively short time that it began to speak of Knowledge Management and at that time was very associated with Information Technologies, as a means to collect, process and store more and more, larger amounts of information. Information Technologies has had, from a few years back, an extremely important role in organizations, were initially adopted in order to automate the operational processes of organizations, that support their daily activities and in recent times Information Technologies within organizations has evolved rapidly. All the knowledge, even to the least relevant to a particular business area, is fundamental to support the process of decision making. The organizations to achieve better performances and to transcend the goals that were initially propose, tend to provide itself with more and better Information Systems, as well as, the use of various methodologies and technologies available today. Consequently, in recent years, many organizations have demonstrated a crucial need for integrating all their information, which is dispersed by the diver constituents departments. For top managers (but also for other employees) may have ready in time, pertinent, truthful and reliable information of the organization they represent, need access to good Information Technology Systems. In an action that they can act more effectively and efficiently in decision making, for having managed to get through these means the maximum possible advantage of the information, and so, present better levels of organizational success. Also, the systems of Business Intelligence and Information Technologies its associated, use existing data on organizations to provide relevant information for decision making. But, in order to achieve these levels as satisfactory, organizations need human resources, because how can they be competitive without skilled workers. Thus, arises the need for organizations to recruit called today “Knowledge Workers”, they are the individuals enable to interpret the information within a specific domain. They detect problems and identify alternatives, with their knowledge and discernment they work to solve these problems, helping considerably the organizations that represent. And, using Luís Miguel Borges – Gestão e Trabalhadores do Conhecimento em Tecnologias da Informação (UML) ULHT – ECATI 8 methodologies and technologies of Knowledge Engineering as modeling, create and manage a history of knowledge, including tacit knowledge, on various business areas of the organization, that can be explicit in the abstract models, that can be understood and interpreted easily, by other workers with equivalent levels of competence.

A matter of fundamentals : sound and silence in the radio drama of Samuel Beckett

Samuel Beckett was arguably one of the most influential writers of the 20th century. Known for his stage plays, including the renowned En attendant Godot (1948), Beckett’s contribution to the field of radio drama is often overlooked. His corpus of radio dramas included some of the most innovativeradio works of the post-World War II period. For Beckett, radio drama was not exclusively verbocentric, for he always maintained that his work was “a matter of fundamental sounds (no joke intended) made as fully as possible” (Frost 362). His (radio) drama aesthetics defined a strict hierarchy of sound whereby the dramatist balances sound effects, music and the characters’ dialogue – and the use of silence. In this essay, I examine the juxtaposition of sound and silence in Samuel Beckett’s most influential radio dramas: All That Fall, Embers, Words and Music and Cascando. In the end, this essay will show that the sounds and silence employed in Beckett’s radio dramatic works were inextricably linked, which added to the overall meaning of his dramas.

O Binómio «Esquerda/Direita» no Portugal pós-25 de Abril

A esquerda e a direita estão, passados 35 anos, diferentes do que eram, mas iguais na clivagem que as distingue. PCP e CDS/PP alargaram até o grau de polarização, PS e PSD tornaram-se amiúde irmãos siameses que o eleitorado premeia ou penaliza ciclicamente, mas aos quais concede, desde 1975, o seu voto de confiança. na verdade, desde então o PCP está sozinho à esquerda e o CDS/PP à direita, aguardando sempre que um dos partidos chamados a formar governo (PS ou PSD) necessite de uma coligação.

Determinantes sociais condicionantes das altas clínicas dos utentes da rede nas UCCI: um estudo de caso

Introdução: O adiamento das altas clínicas nas Unidades de Cuidados Continuados Integrados (UCCI) por motivos sociais é actualmente considerado um dos principais motivos que impedem a integração atempada de novos clientes na Rede Nacional de Cuidados Continuados, RNCC, daqui em diante designada como a REDE. Este atraso tem impacto ao nível da recuperação e estabilização dos utentes, bem como ao nível de eficiência e eficácia da UCCI, não podendo deixar de se considerarem os aspectos sociais e económicos. Objectivo Geral: Identificar os determinantes que influenciam as altas clínicas em UCCI. Métodos e População do Estudo: Este é um estudo de caso colectivo, em que os dados observacionais, transversais, são recolhidos por meio de questionário de auto-relato (por cada área de intervenção directa) e por análise dos processos de consulta de pacientes. O objecto desta pesquisa abrange dois grupos: o grupo de amostra composto por 70 profissionais de saúde que lidam directamente com os utentes e o grupo amostra composto de utentes internados na UCCI L Nostrum, com alta clínica entre 1/1/2011 e 31/12/2012, e que foram integrados através da REDE. Foram recolhidos os dados de 293 utentes sendo objecto de estudo os casos de 83 utentes integrados através da REDE e com prolongamento de internamento por motivos sociais. Resultados: Na percepção dos profissionais de saúde, as respostas institucionais apresentam-se como a condicionante mais indicada, tanto para os utentes em geral, com 22 indicações (88%) como para os utentes da REDE, com 10 indicações (40%). Relativamente aos motivos familiares há referência de 76% para os utentes em geral e de 36% para os utentes da REDE. Os motivos económicos também apresentam, para os profissionais inquiridos, um valor expressivo (68%) nos utentes em geral, estando nos da REDE este factor condicionante a par com os motivos familiares (36%). Os motivos estruturais têm menor expressão tanto nos utentes em geral (32%) como nos utentes da REDE (16%). “Outros” para os utentes em geral, refere-se a dependência funcional (4%). Nos motivos familiares, para os utentes em geral, 23 (92%) foi mais vezes indicada a insuficiência de suporte familiar, para os utentes da REDE, 13 (52%). A ausência de suporte familiar, para os utentes em geral, representa 48% das respostas, seguindo-se o suporte inadequado (28%) e a ausência de cuidadores (24%). Para os utentes da REDE, o suporte inadequado apresenta-se como segundo motivo (7%), seguindo-se a ausência de suporte familiar (16%). Na percepção dos profissionais, os utentes da REDE estão também condicionados pela distância geográfica (8%) da sua área residencial. Em termos estruturais, os motivos mais assinalados pelos profissionais para a generalidade dos utentes foram as barreiras físicas à mobilidade (80%) e a habitação sem condições básicas de habitabilidade (78%). Os mesmos motivos foram assinalados para os utentes da REDE, barreiras físicas à mobilidade (40%) e habitação sem condições de habitabilidade (28%). No entanto, relativamente aos utentes em geral, a ausência de habitação (29%) e a distância geográfica (4%) também foram motivos assinalados. Dos motivos económicos percebidos pelos profissionais, a insuficiência de rendimentos é o factor mais assinalado pela generalidade dos utentes (84%) e pelos da REDE (68%), seguida da percepção da capacidade de reposta limitada das instituições, 64% para a generalidade dos utentes e 28% para os da REDE e por fim os tipos de respostas insuficientes para as necessidades individuais dos utentes (20% dos utentes em geral e 12% da REDE). No total dos dois anos, 2011 e 2012, verificaram-se na UCCI L Nostrum 293 prorrogações (100%) das quais 210 (71,6%) foram consideradas dentro do prazo e justificadas com motivos clínicos, enquanto 83 (28,3%) foram efectivamente protelamentos por motivos sociais, tendo em conta que nestes casos os utentes já não tinham critérios clínicos que justificassem a sua permanência na UCCI. Das 210 prorrogações consideradas dentro do prazo e justificadas com motivos clínicos, 93 (44,3%) foram-no por tempo de espera para transferência de UCCI. Em 2011, dos 146 utentes com alta protelada (100%), 50 utentes (34,2%) permaneceram na UCCI por motivos sociais, enquanto em 2012 houve registo de 33 casos de protelamento (22,4%) em 147 (100%) altas prorrogadas. Conclusões: Dos factores identificados como motivo de protelamento nos 83 utentes, estritamente por motivos sociais, destaca-se o protelamento de alta por espera de integração em equipamento/resposta adequada, nomeadamente lar ou serviços de apoio domiciliário (79,5%), seguindo-se a insuficiência de rendimentos do utente/familiares para contratação de serviços ou resposta institucional (74,7%), a inexistência de condições habitacionais para regresso ao domicílio (63,9%) e a insuficiência de suporte familiar (54,2%). Regista-se também a inadequação do suporte familiar (31,3%), a inexistência de suporte familiar (28,9%) e, em menor percentagem, a ausência de condições estruturais (13,3%). A ausência de domicílio (sem abrigo) (8,4%) e a ausência de rendimentos (4,8%) também foram factores inibidores da alta clínica. Dos 293 utentes identificados que tiveram protelamento da alta por motivos sociais verificou-se que 144 (49,1%) dos utentes permaneceram unicamente pela existência de condicionantes institucionais e familiares/estruturais. Aspectos éticos: ao longo deste estudo, foram assegurados e respeitados, todos os procedimentos de garantia da confidencialidade e rigor na recolha dos dados, e a não interferência nas dinâmicas da instituição, dos utentes e dos profissionais.

Anatomías contrariadas: la representación del cuerpo en la literatura sobre los Andes (Estudios)

La autora analiza tres textos latinoamericanos que muestran construcciones del imaginario andino, extendidas a ciertos estereotipos sobre la corporalidad andina: frágil, dolorida, para la cual la esperanza de liberación radica en un azar. En «Boletín y Elegía de las Mitas», César Dávila presenta una versión del cuerpo indio «exclusivamente centrada en la vejación de lo anatómico» (de su cabeza y genitales, de órganos tan profundos como el corazón y el esqueleto), con lo que el cuerpo desnudo y forzado se convierte en ajeno. En «El sueño del Pongo», de José María Arguedas, el cuerpo del indio oprimido es diminuto, y porta una «gestualidad comprimida que se pone en juego a partir de posturas humilladas». Pese al final aparentemente optimista de ambos textos, se trata de productos culturales que cumplen un rol en el ejercicio de control social. En «Barraquera», de José de la Cuadra, el cuerpo de esta mujer es fundado a partir de violaciones, muertes y migraciones forzadas: habituado a sufrir y callar, para este cuerpo el dolor se convierte en la única vía posible de acceso al placer. Se remarca que el tiempo cronológico de los tres relatos es el de la espera, el tiempo del destino. Para estos cuerpos-lugares siempre vulnerables y violentados, burlados o invisibilizados, lo fatal fundamentaría un cierre de lo histórico.

The social relations of business representation and devolved governance in the United Kingdom

The reform of regional governance in the United Kingdom has been, in part, premised on the notion that regions provide new territories of action in which cooperative networks between business communities and state-agencies can be established. Promoting business interests is seen as one mechanism for enhancing the economic competitiveness and performance of 'laggard' regions. Yet, within this context of change, business agendas and capacities are often assumed to exist 'out there, as a resource waiting to be tapped by state institutions. There is little recognition that business organisations' involvement in networks of governance owes much to historical patterns and practices of business representation, to the types of activities that exist within the business sector, and to interpretations of their own role and position within wider policymaking and implementation networks. This paper, drawing on a study of business agendas in post-devolution Scotland, demonstrates that in practice business agendas are highly complex. Their formation in any particular place depends on the actions of reflexive agents, whose perspectives and capacities are shaped by the social, economic, and political contexts within which they are operating. As such, any understanding of business agendas needs to identify the social relations of business as a whole, rather than assuming away such complexities.

Redefinition of the kilogram: a decision whose time has come

The kilogram, the base unit of mass in the International System of Units (SI), is defined as the mass m(K) of the international prototype of the kilogram. Clearly, this definition has the effect of fixing the value of m(K) to be one kilogram exactly. In this paper, we review the benefits that would accrue if the kilogram were redefined so as to fix the value of either the Planck constant h or the Avogadro constant NA instead of m(K), without waiting for the experiments to determine h or NA currently underway to reach their desired relative standard uncertainty of about 10−8. A significant reduction in the uncertainties of the SI values of many other fundamental constants would result from either of these new definitions, at the expense of making the mass m(K) of the international prototype a quantity whose value would have to be determined by experiment. However, by assigning a conventional value to m(K), the present highly precise worldwide uniformity of mass standards could still be retained. The advantages of redefining the kilogram immediately outweigh any apparent disadvantages, and we review the alternative forms that a new definition might take.

A randomised controlled trial of cognitive behaviour therapy for psychosis in a routine clinical service

Objective: To evaluate CBTp delivered by non-expert therapists, using CBT relevant measures. Methods: Participants (N=74) were randomised into immediate therapy or waiting list control groups. The therapy group was offered six months of therapy and followed up three months later. The waiting list group received therapy after waiting nine months (becoming the delayed therapy group). Results: Depression improved in the combined therapy group at both the end of therapy and follow-up. Other significant effects were found in only one of the two therapy groups (positive symptoms; cognitive flexibility; uncontrollability of thoughts) or one of the two timepoints (end of therapy: PANSS general symptoms, anxiety, suicidal ideation, social functioning, resistance to voices; follow-up: power beliefs about voices, negative symptoms). There was no difference in costs between the groups. Conclusions: The only robust improvement was in depression. Nevertheless, there were further encouraging but modest improvements in both emotional and cognitive variables, in addition to psychotic symptoms.

Modeling cumulative evidence for freedom from disease with applications to BSE surveillance trials

This investigation deals with the question of when a particular population can be considered to be disease-free. The motivation is the case of BSE where specific birth cohorts may present distinct disease-free subpopulations. The specific objective is to develop a statistical approach suitable for documenting freedom of disease, in particular, freedom from BSE in birth cohorts. The approach is based upon a geometric waiting time distribution for the occurrence of positive surveillance results and formalizes the relationship between design prevalence, cumulative sample size and statistical power. The simple geometric waiting time model is further modified to account for the diagnostic sensitivity and specificity associated with the detection of disease. This is exemplified for BSE using two different models for the diagnostic sensitivity. The model is furthermore modified in such a way that a set of different values for the design prevalence in the surveillance streams can be accommodated (prevalence heterogeneity) and a general expression for the power function is developed. For illustration, numerical results for BSE suggest that currently (data status September 2004) a birth cohort of Danish cattle born after March 1999 is free from BSE with probability (power) of 0.8746 or 0.8509, depending on the choice of a model for the diagnostic sensitivity.

Evaluation of the cumulative evidence for freedom from BSE in birth cohorts

Substantial resources are used for surveillance of bovine spongiform encephalopathy (BSE) despite an extremely low detection rate, especially in healthy slaughtered cattle. We have developed a method based on the geometric waiting time distribution to establish and update the statistical evidence for BSE-freedom for defined birth cohorts using continued surveillance data. The results suggest that currently (data included till September 2004) a birth cohort of Danish cattle born after March 1999 is free from BSE with probability (power) of 0.8746 or 0.8509, depending on the choice of a model for the diagnostic sensitivity. These results apply to an assumed design prevalence of 1 in 10,000 and account for prevalence heterogeneity. The age-dependent, diagnostic sensitivity for the detection of BSE has been identified as major determinant of the power. The incorporation of heterogeneity was deemed adequate on scientific grounds and led to improved power values. We propose our model as a decision tool for possible future modification of the BSE surveillance and discuss public health and international trade implications.

Subcontract and supply enquiries in the tender process of contractors

In the tender process, contractors often rely on subcontract and supply enquiries to calculate their bid prices. However, this integral part of the bidding process is not empirically articulated in the literature. Over 30 published materials on the tendering process of contractors that talk about enquiries were reviewed and found to be based mainly on experiential knowledge rather than systematic evidence. The empirical research here helps to describe the process of enquiries precisely, improve it in practice, and have some basis to support it in theory. Using a live participant observation case study approach, the whole tender process was shadowed in the offices of two of the top 20 UK civil engineering construction firms. This helped to investigate 15 research questions on how contractors enquire and obtain prices from subcontractors and suppliers. Forty-three subcontract enquiries and 18 supply enquiries were made across two different projects with average value of 7m. An average of 15 subcontract packages and seven supply packages was involved. Thus, two or three subcontractors or suppliers were invited to bid in each package. All enquiries were formulated by the estimator, with occasional involvement of three other personnel. Most subcontract prices were received in an average of 14 working days; and supply prices took five days. The findings show 10 main activities involved in processing enquiries and their durations, as well as wasteful practices associated with enquiries. Contractors should limit their enquiry invitations to a maximum of three per package, and optimize the waiting time for quotations in order to improve cost efficiency.

Comparative performance of UK PFI and non-PFI hospitals

Since the first PFI hospital was established in 1994, many debates centred on the value for money and risk transfer in PFIs. Little concern is shown with PFI hospitals’ performance in delivering healthcare. Exploratory research was carried out to compare PFI with non‐PFI hospital performance. Five performance indicators were analysed to compare differences between PFI and non‐PFI hospitals, namely the length of waiting, the length of stay, MRSA infection rate, C difficile infection rate and patient experience. Data was collected from various government bodies. The results show that only some indexes measuring patient experience emerge statistically significant. This leads to a conclusion that PFI hospitals may not perform better than non‐PFI hospitals but they are not worse than non‐PFI hospitals in the delivery of services. However, future research needs to pay attention to reliability and validity of data sets currently available to undertake comparison.

iTrench: a study of user reactions to the use of information technology in field archaeology

This article describes work undertaken by the VERA project to investigate how archaeologists work with information technology (IT) on excavation sites. We used a diary study to research the usual patterns of behaviour of archaeologists digging the Silchester Roman town site during the summer of 2007. Although recording had previously been undertaken using pen and paper, during the 2007 season a part of the dig was dedicated to trials of IT and archaeologists used digital pens and paper and Nokia N800 handheld PDAs to record their work. The goal of the trial was to see whether it was possible to record data from the dig whilst still on site, rather than waiting until after the excavation to enter it into the Integrated Archaeological Database (IADB) and to determine whether the archaeologists found the new technology helpful. The digital pens were a success, however, the N800s were not successful given the extreme conditions on site. Our findings confirmed that it was important that technology should fit in well with the work being undertaken rather than being used for its own sake, and should respect established work flows. We also found that the quality of data being entered was a recurrent concern as was the reliability of the infrastructure and equipment.

A randomised controlled trial of cognitive behavioural treatment for obsessive compulsive disorder in children and adolescents

Cognitive behaviour therapy (CBT) for young people with obsessive compulsive disorder (OCD) has become the treatment of first choice. However, the literature is largely based on studies emphasising exposure and response prevention. In this study, we report on a randomised controlled trial of CBT for young people carried out in typical outpatient clinic conditions which focused on cognitions. A randomised controlled trial compares 10 sessions of manualised cognitive behavioural treatment with a 12-week waiting list for adolescents and children with OCD. Assessors were blind to treatment allocation. 21 consecutive patients with OCD aged between 9 and 18 years were recruited. The group who received treatment improved more than a comparison group who waited for 3 months. The second group was treated subsequently using the same protocol and made similar gains. In conclusion, CBT can be delivered effectively to young people with OCD in typical outpatient settings.

Driving saccade to pursuit using image motion

Within the context of active vision, scant attention has been paid to the execution of motion saccades—rapid re-adjustments of the direction of gaze to attend to moving objects. In this paper we first develop a methodology for, and give real-time demonstrations of, the use of motion detection and segmentation processes to initiate capture saccades towards a moving object. The saccade is driven by both position and velocity of the moving target under the assumption of constant target velocity, using prediction to overcome the delay introduced by visual processing. We next demonstrate the use of a first order approximation to the segmented motion field to compute bounds on the time-to-contact in the presence of looming motion. If the bound falls below a safe limit, a panic saccade is fired, moving the camera away from the approaching object. We then describe the use of image motion to realize smooth pursuit, tracking using velocity information alone, where the camera is moved so as to null a single constant image motion fitted within a central image region. Finally, we glue together capture saccades with smooth pursuit, thus effecting changes in both what is being attended to and how it is being attended to. To couple the different visual activities of waiting, saccading, pursuing and panicking, we use a finite state machine which provides inherent robustness outside of visual processing and provides a means of making repeated exploration. We demonstrate in repeated trials that the transition from saccadic motion to tracking is more likely to succeed using position and velocity control, than when using position alone.
