Abstract
In this paper, we investigate a new variant of the multi-commodity network flow problem, taking into consideration multiple transport lines and time windows. This variant arises in a city logistics environment, more specifically in a long-haul passenger transport system that is also used to transport urban freight. We propose two mixed integer programming models for two objective functions: minimization of network operational costs and minimization of travel times. Since the problems under study are NP-hard, we propose three size reduction heuristics. In order to assess the performance of the proposed algorithms, we carried out computational experiments on a set of synthetic problem instances. We use the relative percentage deviation as performance criterion. For the cost objective function, a LP-and-Fix algorithm outperforms other methods in most tested instances, but for the travel time, a hybrid method (size reduction with LP-and-Fix algorithm) is, in general, better than other approaches.

Abstract
Background: The multimedia capturing of live lectures has increased within higher education institutions, even in the pre-COVID-19 period. Despite student satisfaction, the video lecture capture (VLC) influence on students' attainment and achievement of intended learning outcomes is controversial. Methods: To explore the impact of VLC, a cross-sectional study across 2016/17 (n=209 students) and 2017/18 (n=206 students) was conducted in the course of Mechanistic Toxicology in Pharmaceutical Education. Results: The results showed that 73% and 90% of the assessed students entirely viewed the videos of theoretical (550 minutes) and practical/laboratory classes (250 minutes), respectively. VLC impacted student attainment and the achievement of intended learning outcomes on the capacity to understand the subjects and apply knowledge. Conclusion: The effectiveness of VLC is to be considered under the framework of constructive alignment and the specificities of the course.

Abstract
The support and influence of industrial business associations (IBAs) for the internationalisation process of small and medium-sized enterprises (SMEs) is questioned. This qualitative case study on the textile industry in Portugal illustrates how SMEs are influenced by their IBA. Findings suggest that it has a preponderant role in supporting the international expansion of associated SMEs. Particularly, the promotion and organisation of trade fairs seem to foster first entries and continuous international expansion in the same way the IBA seems to influence their foreign market selection. However, SMEs feel that the IBA’s work could still be improved by their facilitating more matchmaking processes, promoting collaborations, improving their seizing of available internationalisation opportunities, and providing more information about agents and distributors in foreign markets. Thus, we can say that, despite the internet and global opportunities that firms can directly benefit from, the role of IBAs is still relevant for SME’s internationalisation, and there is still room for improvement.

Abstract
Digital transformation is a broad description of efforts to introduce new technologies within and across organizations with the potential to revolutionize the way they function and perform. Digital transformation may be addressed at multiple levels of analysis, and this paper focuses on the enterprise level. This includes the organization, its people, systems, tools and technologies, and suppliers and partners that combined create valued outcomes that sustain the enterprise and advance its objectives. Collectively, this is a complex sociotechnical system (STS), and digital transformation is an intervention in a STS of potentially profound scope. Classical STS theory emerged from analysis of individuals and work groups and principles have been defined for the design of work systems at that level. We explore how STS design principles may be applied to the enterprise-level challenges associated with digital transformation. We present an enterprise-level framework that describes a process and methods that are consistent with STS design principles and illustrates how existing systems analysis methods and artifacts may be used to design an enterprise level STS. We review some artifacts employed in digital transformation efforts, including enterprise reference architectures, to better understand how they might function as means to foster communication and collaboration across multiple disciplines and domains in the STS design process.

Abstract
The topic of digital transformation has become increasingly prevalent in recent decades. Its importance is justified by the fact that not only can it change the way companies operate, but also bring to light new business strategies. Indeed, companies have ramped up operational data collection opportunities and adopted digital practices to facilitate new flows of design information, allow teams to interoperate in different ways, or improve system performance. Given that a digital transformation occurs under certain sociotechnical contexts and with specific purposes, their success can critically depend on the ability to unambiguously describe this context and the intended transformation in the form of new operational scenarios. One of the challenges faced when attempting a digital transformation is that these efforts can be ad-hoc and poorly structured, which does not tie the transformation to strategic objectives and operational strengths and limitations. This paper aims at addressing this issue by leveraging an existing systems engineering analysis method called Concept of Operations to provide structure to the digital transformation process. Our work shows that this method has the potential to accelerate the sociotechnical system redesign cycle and generate actionable decisions aligned with strategic goals and operational strengths and limitations. © 2022 The authors and IOS Press.

Abstract
The requirements of a software are the characteristics of the system, being identified based on information provided by the users or by experts in the business; and the effective management of this information is essential to ensure that the system meets the needs of those who will use it. According to research, one of the problems that negatively impacts the software development process is related to the conduction of the project requirements management activity. And in order to alleviate this problem, we carried out a research to verify if taxonomies, as tools used by the area of information management, can be applied in the context of requirements management. For this, we developed a taxonomy to meet a real software project and the results were evaluated in relation to its complexity, satisfaction, resources involved and adaptability. The present research is characterized in terms of nature as an applied research, aiming at solving real-world problems; as for the objectives, as exploratory and descriptive; and as for the approach, mixed methods are used, since it combines qualitative and quantitative forms of research in the same study. As for the methodological procedures, the bibliographic research was chosen to understand the concepts related to information management, taxonomies and requirements management. The evaluation results showed that taxonomies can contribute to the activities of the requirements management process and consequently increase the chances of project success.
