Zaíta não será esquecida: a vida em fragmentos e as crianças em Conceição Evaristo
Publication . Paolinelli, Luísa Antunes; Marinho Antunes Paolinelli, Luisa; Fernandes, Sofia Figuermann e
Este estudo procura refletir sobre a
violência em comunidades brasileiras empo
brecidas e com uma forte presença criminal,
conforme retratado pela autora brasileira
contemporânea Conceição Evaristo, a partir da
análise do conto «Zaíta esqueceu de guardar
os brinquedos» (2014). Considerando a forma
extrema de agressão sobre as crianças, como
o uso da força física ou psicológica para impo
sição de uma vontade e controlo, esta passa
por condicionamentos que se manifestam por
processos de autoritarismo, repressão, segre
gação e exclusão social. O conto analisa as
consequências de um modo de pensar, agir e
de se colocar em relação ao outro marcado
por experiências diretas e indiretas de vio
lência que se replicam num círculo vicioso e
que resultam em vidas que são como o brin
quedo mutilado e perdido da pequena Zaíta.
O espiritismo nos autores madeirenses da primeira metade do século XX: de Reis Gomes a Vasco Mimoso, entre ciência, cristianismo e fenómenos psíquicos ocultos
Publication . Castro, Fernanda de; Paolinelli, Luísa M. Antunes; Marinho Antunes Paolinelli, Luisa
Se a Europa do fim do século xix e início do século xx, por um lado, se interessava
pela ciência psicológica e pela pesquisa científica relacionada com a elaboração de conceitos como
saúde, saúde mental, doença, terapia, normalidade psíquica, anormalidade, histeria, demência, entre
outros, por outro, sentia a atração por áreas como a parapsicologia e o espiritismo. Na realidade,
cultura científica e parapsicologia não raro conviviam, numa tentativa de explicar o homem nos seus
aspetos mais recônditos, mais dúbios. Esta aproximação entre cultura psicológica e parapsicologia
atraiu, de forma diferenciada, diversos autores, quer na conceção de tramas, ambientes e personagens,
quer, no caso de escritores europeus, como Pirandello ou Fogazzaro, e de madeirenses, como o mais
conhecido Reis Gomes e o diretor de A Regeneração, Vasco Mimoso, num interesse comum pela
ciência, pelo misticismo e pela parapsicologia que os levou a dirigir a tensão gnoseológica para a
análise e o estudo da parte menos clara e visível do humano.
User-perceived quality and functional suitability of representations of DEMO’s process and fact models: conclusions from a family of three studies
Publication . Pacheco, Dulce; Aveiro, David; Pinto, Duarte; Freitas, Vítor; Pacheco, Dulce; Aveiro, David; Pinto, Duarte
Clear and cognitively compelling diagrams representing organizational reality are crucial
for structured communication, proper information systems implementation, and ultimately, organizational
success. Design and Engineering Methodology for Organizations (DEMO), a standard from the field of
Enterprise Engineering, provides representations for Process and Fact Models. However, the complexity
of its notations can impede stakeholder understanding. New representations for these models have been
proposed, but lacked formal evaluation across diverse user groups. This paper addresses this gap by assessing
user perception of both standard and newly proposed DEMO representations. We conducted a family
of three evaluation studies using mixed research methods across distinct user groups (N = 32). Results
show a unanimous preference for the new representations in terms of perceived quality and functional
suitability, supporting most of our hypotheses. Our study does not support the claim that familiarity with
the modeling language improves perception of empirical quality. This research expands the knowledge base
on the underexplored area of user experience within DEMO models and representations.
Organizational engineering processes: integration of the cause-and-effect analysis in the detection of exception kinds
Publication . Pacheco, Dulce; Aveiro, David; Tenório, Nelson; Pacheco, Dulce; Aveiro, David
Enterprises are dynamic systems that struggle to adapt to the constant changes in their environment. The
complexity of these systems frequently originates inefficiencies that turn into the loss of resources and might
even compromise organizations’ viability. Control and G.O.D. (sub)organizations allow enterprises to specify
measures and viability norms that help to identify, acknowledge, and handle exceptions. Organizational
engineering processes are deployed to treat dysfunctions within the G.O.D. organization but often fail to
eliminate or circumvent the root cause of it. In this paper, we propose an extension in the model to allow a
thorough investigation of the root causes of dysfunctions within the organizational engineering processes.
Grounded on the seven guidelines for Information System Research in the design-science paradigm, we claim
that the organizational engineering process should be supplemented with a systematic and broader
investigation of causes, namely the Ishikawa approach of cause-and-effect analysis. The main contributions
of this paper are the improvement of the organizational engineering process for handling unexpected
exceptions in reactive change dynamics and the freely available Dysfunctions Bank with common
dysfunctions and its probable causes. This work should trigger a reduction in the number of organizational
dysfunctions and help to keep updated the organizational self and the organization’s ontological model.
MementoKey: keeping passwords in mind
Publication . Jeong, Bongkeum ; Vallat, Alexander; Csikszentmihalyi, Chris ; Park, Junwu ; Pacheco, Dulce; Pacheco, Dulce
In this paper, we introduce a novel system of password generation, MementoKey, consisting of private
words that exist only in a user’s memory and a corresponding set of public (non-secret) words that
will facilitate users’ recall of the private words, which they are associated with. We will demonstrate
how MementoKey offers a useful alternative to existing options for storing passwords in password
managers, or to using cryptographically weak, but memorable, passwords. We have conducted a
user study to evaluate the word-association technique for recalling passwords, and the effectiveness of our prototype software training and checking system to guide the user successfully through the
memorization process.
Our study involving 60 diverse participants indicates that our prototype can effectively lead users
through a visualization and memorization technique to create a strong word-association memory
between pairs of adjectives and nouns.
