- An agile business process and practice meta-modelPublication . Zacarias, Marielba; Martins, Paula Ventura; Gonçalves, António; CruzCunha, M. M.; Varajao, J. E. Q.; Rijo, R.; Martinho, R.; Peppard, J.; SanCristobal, J. R.; Monguet, J.Business Process Management (BPM) encompasses the discovery, modelling, monitoring, analysis and improvement of business processes. Limitations of traditional BPM approaches in addressing changes in business requirements have resulted in a number of agile BPM approaches that seek to accelerate the redesign of business process models. Meta-models are a key BPM feature that reduce the ambiguity of business process models. This paper describes a meta-model supporting the agile version of the Business Process and Practice Alignment Methodology (BPPAM) for business process improvement, which captures process information from actual work practices. The ability of the meta-model to achieve business process agility is discussed and compared with other agile meta-models, based on definitions of business process flexibility and agility found in the literature.

- An agile business process improvement methodologyPublication . Martins, Paula Ventura; Zacarias, Marielba; CruzCunha, MM; Varajao, JEQ; Rijo, R; Martinho, R; Peppard, J; SanCristobal, JR; Monguet, JAdoption of business process improvement strategies are now a concern of most organisations. Organisations are still facing challenges and finding transient solutions to immediate problems. The misalignment between IT solutions and organisational aspects evolves across space and time showing discrepancies. Unfortunately, existing business process approaches are not according with continuous business process improvement involving business stakeholders. Considering this limitation in well-known Business Process (BP) methodologies, this paper presents a comparative study of some approaches and introduces agility in the Business Process and Practice Alignment Methodology (BPPAM). Our intention is to present observed problems in existing approaches and introduce agility in our proposal to address features, like the alignment between daily work practices and business process descriptions, in a simple and agile way.

- Applying the business process and practice alignment meta-model: Daily practices and process modellingPublication . Martins, Paula Ventura; Zacarias, MarielbaBackground: Business Process Modelling (BPM) is one of the most important phases of information system design. Business Process (BP) meta-models allow capturing informational and behavioural aspects of business processes. Unfortunately, standard BP meta-modelling approaches focus just on process description, providing different BP models. It is not possible to compare and identify related daily practices in order to improve BP models. This lack of information implies that further research in BP meta-models is needed to reflect the evolution/change in BP. Considering this limitation, this paper introduces a new BP meta-model designed by Business Process and Practice Alignment Meta-model (BPPAMeta-model). Our intention is to present a meta-model that addresses features related to the alignment between daily work practices and BP descriptions. Objectives: This paper intends to present a meta-model which is going to integrate daily work information into coherent and sound process definitions. Methods/Approach: The methodology employed in the research follows a design-science approach. Results: The results of the case study are related to the application of the proposed meta-model to align the specification of a BP model with work practices models. Conclusions: This meta-model can be used within the BPPAM methodology to specify or improve business processes models based on work practice descriptions.
- BAM: business alignment methodologyPublication . Zacarias, Marielba; Martins, Paula VenturaInformation flows across the organization are complex and procedures employed to understand, share and control organizational knowledge and experiences should be properly supported by collaborative environments. Nevertheless, few collaborative methodologies had been proposed to describe and evolve business processes. In the future, business processes models should be the result of cross-team and cross-departmental collaboration, with involved business people sharing their personal knowledge and formalizing it. This paper focuses on a methodology for business process discovery and the importance to integrate local information into coherent and sound process definitions. Business Alignment Methodology (BAM) is a methodology that provides guidance about how organizational practices and knowledge are gathered to contribute for business process improvement against current BPM approaches.
- Collaborative method to maintain business process models updatedPublication . Castela, Nuno; Dias, Paulo; Zacarias, Marielba; Tribolet, Jose M.Business process models are often forgotten after their creation and its representation is not usually updated. This appears to be negative as processes evolve over time. This paper discusses the issue of business process models maintenance through the definition of a collaborative method that creates interaction contexts enabling business actors to discuss about business processes, sharing business knowledge. The collaboration method extends the discussion about existing process representations to all stakeholders promoting their update. This collaborative method contributes to improve business process models, allowing updates based in change proposals and discussions, using a groupware tool that was developed. Four case studies were developed in real organizational environment. We came to the conclusion that the defined method and the developed tool can help organizations to maintain a business process model updated based on the inputs and consequent discussions taken by the organizational actors who participate in the processes.
- Contribution of remote sensing products to the management of offshore aquaculture at Sagres, SW PortugalPublication . Icely, John; Moore, Gerald; Danchenko, Sergei A.; Goela, Priscila; Cristina, Sónia; Zacarias, Marielba; Newton, AliceRemote sensing can address important issues affecting offshore aquaculture such as prediction of Harmful Algal Blooms. In situ data for nutrients, chlorophyll a (Chla) and phytoplankton community from a site for long-line aquaculture for bivalves off the SW coast of Portugal has been compared during a period of upwelling with remote sensing data for Chla, sea surface temperature, salinity, direction and intensity of both currents and winds. On the 11th February the in situ nutrients levels were high and the Chla was low, but by the 12th March the converse was the situation. The evolution of this event could be followed by combining remote sensing and model data from a variety of open source web sites made available by the Earth Observation provider that demonstrated clearly the lags between the physical forcings promoting upwelling and the eventual blooms of phytoplankton.
- Desenvolvimento de uma metodologia passo-a-passo na Química OrgânicaPublication . Fonseca, Custódia; Zacarias, MarielbaA Química Orgânica é uma unidade curricular presente nos curricula de cursos superiores na área de química, biologia e farmácia, registando-se um elevado nível de insucesso em termos de aproveitamento. Embora várias podem ser as causas, certamente uma delas é a dificuldade que os alunos demonstram na aprendizagem do raciocínio logico da matéria teórica o que dificulta, impedindo mesmo, a resolução de exercícios. Neste trabalho pretende-se desenvolver uma metodologia de ensino que permita ao aluno aprender a “pensar em química orgânica” tendo como consequência a resolução de problemas. Trata-se de um método simple baseado na resolução progressiva e personalizada de quizzes implementados com recurso a ferramenta Google Forms.
- Enhancing organizational self-awareness with enterprise modelling frameworksPublication . Tribolet, José; Zacarias, Marielba; Magalhães, Rodrigo; Vaz, Teresa de NoronhaIn a time when technology has made the world smaller and important events take place at an incredibly high pace, organizations constantly need to adapt themselves in order to survive. The challenge of today’s organizations is to develop capabilities of continuous sensing, learning and adjusting to the dynamics of their environments (Magalhães, 2004). An essential requirement of these capabilities entails developing organization’s self-awareness. Human consciousness gives subjects the capacity of self-awareness. Self-aware beings know who they are, how they do things and what they (and others) are doing at any particular moment.

- MILAGE LEARN+: A mobile learning app to aid the students in the study of organic chemistryPublication . Fonseca, Custódia; Zacarias, Marielba; Figueiredo, MauroInteractive learning is one of the approaches that is very important to explore in higher education. Chemistry students own smartphones, laptops, and tablets and could use appropriate apps to complement traditional forms of learning. Here we introduce a new app, MILAGE LEARN+, which integrates several teaching strategies, such as mobile learning, autonomous learning, peer review, blended learning, and gamification. These strategies were evaluated by the student users through an electronic survey form containing 15 statements with responses graded on a Likert-type scale. Students rate the usage of novel teaching/learning strategies in the MILAGE LEARN+ app as something very positive. There is a positive correlation between the relative grades obtained using MILAGE LEARN+ and the final exam grades. Thus, in this experience, students with better results in MILAGE LEARN+ also had better results in the final exam.
